[Tinyos-help] telosb with windows 8
Has anyone used serial port communication to a telosb mote under Windows 8? I have a program that works fine under XP but I don't seem to be able to get the right FTDI driver magic under 8. We, may have, followed the instructions for loading their VCP driver. When the program starts it detects that there are devices on COM3 and COM5, but neither of those port names actually connect to the mote. To make matters worse I am debugging this over the phone with someone who knows nothing about Windows on the other end, I do not have any of the hardware to test...and its all TOS1.x thx MS ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
Re: [Tinyos-help] Z1 High speed i2c accelerometer sampling
There are some intriguingly named files containing Stream and DMA in the ...tinyos-2.x_main/tos/chips/msp430/adc12 directory. Some of them even have comments which reference TEP documents that might explain what they are trying to do. Maybe one of them will allow you to run the ADC at higher rates... In T1 with the mica's (what I know) one could free-run a single ADC at low audio rates by bypassing most of TOS.

Re: [Tinyos-help] Packet contents
I'm just starting to deal with T2's Listen and ListenRaw (under Ubuntu) and found that ListenRaw has some kind of timing and error issues. If I run it in a shell window it just hangs around and prints no message data, but if I step through it in Eclipse I get a few lines of output before (it appears) that the read() returns a -1 and the main loop exits. However the internal read thread is still running so the process just hangs at that point. I don't think I have the patience to compare its operation to Listen which seems to work OK, so I'm probably going to just drink the kool-aide and move on. I did run across a mention of an extra byte in the message header when using some kind of secure messaging protocol, probably in one of the TEPs (111, 113, 116 seem to deal with messaging). That would offset your payload start, and maybe even mess up the length calculation. In the course of putzing with this I found that the tinyos.jar contains the net/tinyos/packet/Serial.class which is used by Packetizer, but the Serial.java file is missing from my source tree. I can re-compile the source I have if I include the given tinyos.jar but can't actually reconstruct the jar itself. I found a couple of instances on this list of previous complaints about this file being missing, but no offered solutions. I got my source tree from here: git clone -v git://github.com/tp-freeforall/prod tinyos-2.x as per E.Decker's instructions at: https://github.com/tp-freeforall/prod/blob/tp-master/00b_Development_Environment MS On 02/06/2013 02:59 AM, Jan Hauer wrote: The java listen app should display all bytes. For debugging you could use the printf library (see apps/tests/TestPrintf) on the BaseStation and make a hexdump of your entire message_t. Maybe also make sure message_t payload is big enough (e.g. for cc2420 put CFLAGS += -DTOSH_DATA_LENGTH=X, where X is max payload, in Makefile), and, of course, message_t definition must be the same on sender and basestation.

Re: [Tinyos-help] PC to Mote Serial Communication
Almost...Unfortunately all my information is based
on reverse engineering Tinyos 1.x and I think there
may have been some changes in 2.x, so YMMV. I think
there is a TEP document on the docs.tinyos.net site
that might be clearer than me...
I have a package of Java code for host side reading
and writing of messages, but it is targeted at
a platform that I added (USBPIC) so {may,is} be a bit
more confusing than necessary. Here:
http://www.etantdonnes.com/DOC/USBPIC/JavaCommCode.zip
Also there is an old document that _almost_ describes
the format, but I notice that it is not quite correct
either (...it's missing the seqno field...) here:
http://web.archive.org/web/20060627154751/http://www.octavetech.com/pubs/TB5-01+Deciphering+TinyOS+Serial+Packets.pdf
Specifics that I notice right away...
First you are using the old mica2 AM.h format
which will not fly with the telosb. Look in the
telos platform directories for an AM.h file that
specs the correct header format, mostly just adding
some number of useless fields that can be set to 0.
(This may be hidden in T2, I'm not sure if the
basestation code translates telosb headers or not).
Second there are hidden message type and sequence
number fields immediately following the first 0x7E
frame byte:
Each message sent or received has this raw format:
-- added by Packetizer.java framer protocol
byte frame=0x7E;// framing byte...gets escaped in body
byte mtype=0x42;// TOS message type -- used for status
byte seqno; // incremented sequence number
-- user message with appropriate tinyos Header
byte data[MAX_LEN];// header and user payload
-- added by Packetizer.java framer protocol
byte frame=0x7E;
Then the tinyos header Length field is the _payload_
length not including hidden stuff and the other header
fields. In your case it would be 2.
And finally you need to deal with the escaping of
0x7E and 0x7D values in the message body and calculating
the CRC value correctly. It does _not_ include the frame or
escaping bytes...See the two links above for info...

Re: [Tinyos-help] Fwd: errors casting int64_t to float on MSP430
With a 32 bit float you get 24 bits of value and 8 bits of sign so converting from an integer of larger than 24 bits will entail some resolution truncation.

Re: [Tinyos-help] Fill first 8 bytes with memcpy
There's a number of strange and inexplicable things here,
but probably the problem is that you have not set pointer
to point to anything. Try something like:
uint8_t* pointer;
uint8_t buffer[8];
pointer = buffer;
call interface.function(pointer);
or even just:
uint8_t buffer[8];
call interface.function(buffer);
Also, unless you insist on using memcpy(),
you could make your fill loop like this:
for(i=0; i8; i++)
{
pointer[i] = i+1;
}

There's a long history of this one in the help archives: https://www.millennium.berkeley.edu/pipermail/tinyos-help/2010-November/048721.html This is the first time I've heard of it being Mote dependent though...I presume that you use the same MIB510 for the Iris as well?

Re: [Tinyos-help] Random.Rand16() problem
I would assume that rand16() returns a 16 bit random number so you will have to do some calculating to range it to 0-1. But I recommend avoiding floating point on the controller side whenever possible because there is no hardware support for it. I don't know why you get the same number on each call as I would expect the float cast to just give you the int16 values themselves. Maybe try making your random variable an int and see what... Also look at the Random interface, there should be some kind of seed() call which would allow starting the pseudo sequence from a different point on each of your motes. The easiest would be to use the moteID as the seed on each device.

Another way to try it is to find where apit.h is included

Re: [Tinyos-help] Turn off AVcc pin on Telosb
AVcc is, unfortunately, exactly what it says: the Vcc power supply pin. So, nope. Can't shut it off without shutting off the whole telos board. You will need to use one of the other digital I/O pins. Your problem is that a motor draws more current than can be supplied by a regular output pin. If you just want to run your DC motor in one direction you can use a common-emitter transistor driver to boost the current. E.g. look for it here: http://www.williamson-labs.com/480_xtor.htm mshrehm...@gmail.com has also given you another option, using a Hobby Servo motor, which contains a driver of it's own and is operated using variable width pulses from a digital I/O pin. Along with the ease of hardware interface you also get speed and direction control, but you have somewhat more complicated software in making the right pulses. Here's some more info: http://www.horrorseek.com/home/halloween/wolfstone/Motors/svoint_RCServos.html http://www.junun.org/MarkIII/Manual/kevin/servohack.html Where the second site actually sells some of the motors. Usually hobby servos are used for setting rudders and flaps and such where you want to go to a specific angle, but they can be modified for continuous rotation (I think there are some that are continuous, but it's been a while since I looked). I have posted code for ATMEGA timers and hobby servo control here: http://www.etantdonnes.com/Motes/AVR128timers.zip I don't know how easy it would be to port the timer code to MSP chips. Also, should you actually need speed control, I've hacked the servo back into the hacked servos by adding an encoder: http://www.etantdonnes.com/ROBOCAR/encoder/ MS Imene Boudellioua wrote: Hi, Is there a ways to set the AVcc pin in Telosb (Pin 1 in the 10-[in expansion connector U2) to low, or clear it?

Re: [Tinyos-help] Vanderbilt AcousticLocalization java.lang.ClassNotFoundException
To get to the actual TOS release for the nescc builds under T1, I think what you need is something like this in your environment (on Windows): # Set main pointers used by TOS build system to find files # TOSROOT is for external programs, TOSDIR for makefiles TV=tinyos-1.x ## I use this to select specific TOS versions export TOSROOT=C:/cygwin/opt/$TV export TOSDIR=/opt/$TV/tos I believe TOSDIR gets transliterated into a %T variable in the Makefiles, i.e.: /opt/tinyos-1.x/tos This is also required, but you probably already have it set: export MAKERULES=/opt/$TV/tools/make/Makerules Then, if there are extra bits of added TOS goodness in other directories you can include them in the Makefile with PFLAGS (this is probably what the VUTOS variable is trying to do) like this: EXTRATOS=../tos ## or some %T/../contrib... directory PFLAGS += -I$(EXTRATOS)/platform/mica2 \ -I$(EXTRATOS)/interfaces \ -I$(EXTRATOS)/system By figuring out where the files that the compiler is whining about actually are you should be able to add the right directories.

Re: [Tinyos-help] RSSI with tinyos-1.x and mica2
Here's the battery section right out of the MPR/MIB User’s Manual: -- 6.4 MICA2 Battery Voltage Monitor The MICA2 units have an accurate voltage reference that can be used to measure battery voltage (Vbatt). Since the eight-channel, ATMega128L ADC uses the battery voltage as a full scale reference, the ADC full scale voltage value changes as the battery voltage changes. In order to calibrate the battery voltage a precision external voltage reference is required. The MICA2 uses an LM4041 (Mfg: National Semiconductor) 1.223 V reference (Vref) attached to ADC channel 7. NOTE: ADC channel 7 is also used for JTAG debugging on the Atmega128 processor. MICA2s and MICA2DOTs ship with the JTAG fuse enabled. When this fuse is enabled the input impedance of channel 7 is lowered which affects the voltage reference measurement. The fuse must be disabled if ADC channel 7 is used. See below for information on setting ATMega128L fuses. To compute the battery voltage: 1. Set the BAT_MON processor pin (PA5/AD5) to HI. 2. Program the application code to measure ADC Channel 7. 3. Compute battery voltage, Vbatt, from Channel 7’s data by: Vbatt = Vref × ADC_ FS ADC_Count where: Vbatt = Battery voltage ADC_FS = 1024 Vref = External voltage reference = 1.223 V ADC_Count = Data from the ADC measurement of Channel 7 -- So it looks like you have it mostly right. And, yes, the final result is the power at the receiver. Make sure you notice that the Battery Voltage calculation is inverted from what you'd expect: Full-Scale/Count because what you are measuring is a fixed voltage using the battery as the ADC reference...It does actually work once you puzzle it out... I think you can probably ignore the NOTE about Jtag and maybe just add a fudge factor to the battery calculation. Or even just ignore the whole battery thing and use 3.0... Also, if you are just measuring the RSSI of received messages, a measurement is appended to each message in TOS_Msg.strength. However I forget if this is the raw count from ADC-0 or if it has been massaged into Vrssi or even RSSI. Searching the radio code for strength should elucidate this. Note that floating point calculations are rather costly as they are done in software so you might want to use some other methodology, or just the raw Vrssi...

You are using UartStream which is split phase. You need to be catching

The way you have UartStream.sendDone right now doesn't make a whole lot

If you don't know how this works you need to read the basic TinyOS

using UART interface. Now when I send a single command it works
fine. But when I send a series of commands it stops working. I have
tried to create delays after each command but still it does not
work. Can anyone tell me what I can possibly do?
Here is my code :
module GSMmodemC @safe()
{
uses interface Boot;
uses interface Init as UartInit;
uses interface StdControl as UartControl;
uses interface UartStream;
uses interface Leds;
uses interface TimerTMilli;
}
implementation
{
// COMMANDS TO BE SENT
char* uartsendBuf1 = AT\n;
char* uartsendBuf2 = AT+CMGF=1\n;
char* uartsendBuf3 = AT+CMGS=;
char* uartsendBuf4 = +6590140252 tel:%2B6590140252;
char* output = Hello;
char* input;
uint16_t inputlen;
uint8_t recevedByte;
event void Boot.booted() {
call UartInit.init();
call Timer.startPeriodic(3000);
call UartControl.start();
}
static void delay(uint32_t cycles)
{
while (--cycles 0)
{
//nop();
}
}
event void Timer.fired() {
call UartControl.start();
call UartStream.send(uartsendBuf1, 3);
/*call Leds.led1Toggle(); // This
part does not work
delay(5000);
call UartControl.start();
call UartStream.send(uartsendBuf2, 10);
call Leds.led1Toggle();
delay(5000);
call UartControl.start();
call UartStream.send(uartsendBuf3, 8);
call Leds.led1Toggle();
delay(5000);
call UartControl.start();
call UartStream.send(uartsendBuf4, 11);

Re: [Tinyos-help] Help Set-up
Oh Eric, Eric, Eric... Java is not that hard. At least compared to
something like the TOS build system. It even {used to be} a rather
rationalized and simple alternative to most egregious C++ shenanigans.
But anyway... There was one more question in the complaint list:
WARNING: CLASSPATH environment variable doesn't exist.
Your classpath should contain and a pointer
to the cwd (a dot)
Add '.' to your CLASSPATH... See if you can find a place where
CLASSPATH is actually set, in files like .bahsrc or .profile,
and add the dot to the list using a semi-colon ';' as a separator.
Or else do this:
export CLASSPATH=$CLASSPATH;.
I explicitly set PATH and CLASSPATH in my .bashrc so I know what
I'm getting and {think that} I have some control over my world...
And any Java above and beyond 1.4 is fine for TOS, at least until
Oracle destroys the backward compatibility feature. I forget exactly
what went in at 1.4, maybe generics, but some TOS code won't compile
with previous versions. Someone should fix tos-check-env, no?

Re: [Tinyos-help] missing address-of operator?
It's legal and sleazy enough that I might have done it...
I'd almost say it's doing nothing, because message_t*
already includes the message header. But a serial_header
may be a different size (hopefully smaller...).
msg-data is an array of chars and thus already a pointer
(I'm not sure, but putting an in front of it might just
be a noop in this case anyway...). sizeof() is returning
something that is the moral equivalent of an int, and
subtracting that from a char* just backs the pointer
up that number of bytes. The whole thing is counting
on data[] being chars because pointer arithmetic is
done with an implicit sizeof(element) multiplier.
Of your other suggested options, this might be one
way to do it:
(uint8_t *)msg + offsetof(message_t, data)
That gets you to the msg-data pointer again and
enforces that you are working with bytes. But you
might as well go whole hog and subtract the
serial_header size at the same time:
(uint8_t *)msg + offsetof(message_t, data) - sizeof(serial_header_t);
Isn't C fun?

Re: [Tinyos-help] Ultrasonic Sensor with telosB
What fails? Have you made it past the hardware interfacing? Having trouble accessing GPIO? Not getting a good signal? Not able to time the signals correctly? One problem may be that the Ping-thing runs on 5v and the telsob runs on 3.3v. I think you can ignore the over-voltage on the telos pin at low currents (even though the specs say you shouldn't), but the telos may not pull high enough to trigger the Ping. You'll need an oscilloscope to see what's happening at that level. For GPIO there is some kind of GeneralIO component and there used to be a 32Khz timer (and might even be a micro-sec timer now), but I don't use T2 so I don't know what they are.

Kushal Sarkara wrote:
Michael,
Thank you for your response. In keeping with the topic of our original
conversation, I am still trying to implement the ReadStream interface to
sample the MicaZ accelerometer.
After sampling at the prescaler setting that guarantees full precision
(which is ATM128_ADC_PRESCALE_64 for the MicaZ, according to my
calculations) and reading up on the SoundLocalizer application in the
TinyOS Programming Manual, I was wondering if there was any way to alter
the prescaler and use ReadStream (necessary, in my opinion, because I
want to append samples to the log as they are obtained and ReadStream
provides this facility).
The plethora of ADC configuration interfaces makes it confusing for a
TinyOS 2.x and programming novice such as myself to figure out where the
prescaler is altered but I think that I've managed to figure out how
this can be done. What I am having a lot more trouble doing is figuring
out how the ReadStream interface configures the ADC. There must be a
point at which the ReadStream interface specifies what prescaler it
wants to use, right? This led me to search for a module for the
ReadStream interface but I have had no luck.
So,
* Is there a module for the ReadStream interface where the prescaler
etc is set?
* Is it possible to modify the prescaler for ReadStream at all or is
it perpetually set to ATM128_ADC_PRESCALE?
* Is it a good idea to try to mimic the ReadStream operation by
using something like Atm128AdcSingle.getData (like the
SoundLocalizer does) and then trying to store each sample in a
buffer, which would then be appended to the log? My opinion is
that this will result in a lot of processing overheads (and make
it really tough to program, but I don't see just that being a
problem).
I apologize for the lengthy post.

There used to be an interface for this that was actually

more obvious.

After doing some digging, I found the file

/ async command uint8_t ConfigX.getPrescaler() {/

Will it suffice to change the returned value to, for example,
/ATM128_ADC_PRESCALE_32 (/as provided in the

Re: [Tinyos-help] Sending array to the PC
This looks like a structure assignment which should copy
between two pointers:
nmsg-neighbors = tableOfNeighbors;
but I think it might not work correctly with arrays.
You probably need to do a memcpy() to get the contents
of your table into the message. I'm a little rusty on my C
pointers (too much Java lately) so you may have to fiddle
with *'s and 's to get the two sides to be pointers
to the beginning of each array...as written I think
they should both be pointers, but obviously the compiler
doesn't agree...

Re: [Tinyos-help] Tinynode reading from serial port
You might be able to use basestation as a basis for your re-Mote node, but I expect it would be easier to hack up a demo app that reads from an internal sensor like O'scope. The serial messages that basestation expects are the whole TOS Message struct and your wind sensor probably doesn't format it's data that way. You are one the right track with the architecture, but you should use the low level Uart component to read your sensor, replacing the O'scope DemoSensor components. Unfortunately there's not a lot of example code for that...but you can try searching back on this list for discussions of Uart usage. MS Victoria Pimentel wrote: Hello. I have a wind sensor with an RS232 output cable. I want to connect this cable to a tinynode 1 serial port. The wind sensor will send readings to its RS232 output cable and the tinynode 1 will read the sensor readings from the tinynode 1 serial port. Then, I want this tinynode 1 to send to the radio all the messages that it is receiving from the serial port to a tinynode 2 that is connected to a computer. Basically I need to install in the tinynode 1 a base station app that reads from the serial port and sends to the radio, and in the tinynode 2 a base station app that reads from the radio and send through the serial port. I thought I could do this by installing BaseStation on both tinynodes because BaseStation is supposed to be a bridge between the serial and radio channel in any direction. However, the tinynode 1 is not reading from the serial port the messages that the wind sensor is sending. I also thought that I could change the Oscilloscope application to read sensor readings from the serial port instead of the light, voltage or temperature sensors.

Re: [Tinyos-help] Telosb light sensor specification
The tutorials may help in understanding this, but... There should be a config file, in TOS1 mine is Oscilloscope.nc It has these lines: components Main, , DemoSensorC as Sensor, OscilloscopeM.SensorControl - Sensor; OscilloscopeM.ADC - Sensor; Then you need to dig through the ratholes of platform directories to find _which_ DemoSensorC file is being used. Sometimes doing make tmote docs will generate some nice diagrams, but they are about as hard to decipher as the directory structure itself. The DemoSensorC I found for tmotes, again in the last T1 release, is: \tos\platform\msp430\DemoSensorC.nc and it uses InternalTemp as it's sensor... The Oscope supplied with moteiv -- the original commercial tmote -- uses a set of sensors, none of which is Light... MS Baudry Arthur wrote: Ok but I am still a beginner, how do I check that ?

Re: [Tinyos-help] Problems with Atmel128 I2C-Components (iris) with slow I2C sensors
Yes, TOS 1.x, which underlies Moteworks. Although I just noticed that the last release of T1 has a hardware impl for I2C in mica128. Here is what I used, including my small patch to I2CM.nc: http://www.etantdonnes.com/Motes/T1_I2C.zip But I imagine that it will be fairly pointless to try to use it as all the bit access methodology was changed in T2, so there'd be a bunch of porting to do. I also put the spec that I used to debug my problem here, where the section of interest is 3.7 Clock synchronization: http://www.etantdonnes.com/Motes/NXPI2Cspec_UM10204_3.pdf My symptom was that I missed the first bit of the second byte of data from the slow device and thus lost bit sync and failed to complete that byte (if memory serves correctly...). I found this by looking at the data line with a scope and counting the bits... If you really think your problem is the clock stretching issue then it might be better to see how the ATmega hardware thinks it should be dealing with it.

Re: [Tinyos-help] Problems with Atmel128 I2C-Components (iris) with slow I2C sensors
I'm not sure what you mean by slow, but here's something to check...
The T1 version of I2C for the ATmega used bit banging on the TOS
side rather than the controller's I2C hardware -- go figure
I found that it didn't recognize a wait-state-request from
external devices and would lose a bit when reading -- for the
particular device I was using, an SC18 SPI-I2C converter --
which would make it lose message sync and fail. I don't remember
the details, I think the external device can hold one of the
lines to signal that it's not ready -- I made up the name above
but that's what it's doing -- digging through the I2C spec should
turn it up. I fixed it by putting a short busy wait at the end of
each i2c_ack() which slows everything down but makes it work.
If you think this is what you have I can try to find more details.

Hello!
I have a problem with the Atmel128 i2c environment.
I want to read out the k30 co2-sensormodul from senseair.
On this sensor the i2c communication is implemented in software.
Because of that there is an advice in the datasheet
that it might come to problems during the i2c communication
caused by the long response time of the sensor.
The problem was that after an undetermined time the atmel128 i2c
components got in an incorrect state out of which the software can’t
recover.The bus lines stayed high and the return value was EBUSY.
The only way to make the software run fine again was to reset
the node with the watchdog.
However this solution is inadequately.
I analyzed the Atm128I2CMasterPacketP Component and found out that
while the node was in the incorrect state the Atm128I2CMasterPacketP
returned with EBUSY in the else-block at line 220 in the I2CPacket.read()
command.
To solve the problem I added the i2c_abort(EBUSY) call in the else-block.
(1,2)
(same for the I2C.write() command, see software snippet below (2,3))
After that it seemed to work fine.
Now the software recovers out of the incorrect state.
Had somebody else this problem or tested the atmel128 i2c components with
slow i2c sensors?
Is it possible that in this else-Block should be a call to the
i2c_abort(EBUSY)-function?
However there seems to be another bad state, which fortunately occurs more
rarely.
In this state the return value is EOFF and the bus lines also are in high
state.
I tried to add the i2c_abort-function in the else if block above,
but this seemed not to solve the problem. (see the software snippet below)
Has anyone an idea how to solve that problem?
Best regards!
Sebastian

Re: [Tinyos-help] Problems with Atmel128 I2C-Components (iris) with slow I2C sensors
I don't know if what you are working with uses hardware
or software (since I've only used T1) -- if you have started
with Moteworks you probably have T1...
Look at the low level driver and see. If it uses ATmega
hardware I would hope that it supports the so called clock
synchronization mechanism.
Otherwise I put this in I2CM.nc to stretch the period
between bytes received a bit:
void i2c_ack()
{
MAKE_DATA_OUTPUT();
CLEAR_DATA();
pulse_clock();
SET_DATA(); // schip 8/12/09
TOSH_uwait(10); // -- to fix SC18 wait-state non-detect
}

Thank you for your quick reply!
Yes I see my workaround isn’t such a good idea.
With other I2C-Sensors (tsl2561 light sensor) I also hadn’t any problems
and all worked fine. But with the k30 co2 sensor in particular something
doesn’t work.
I also tried to slow down the i2c clock but it didn’t help.
The co2 sensor uses the so called clock synchronization mechanism.
Is it what you mean Michael?
This is described as follows in the I2C- Specification:
“On the bit level, a device such as a microcontroller with or
without limited hardware for the I2C-bus, can slow down
the bus clock by extending each clock LOW period. The
speed of any master is thereby adapted to the internal
operating rate of this device.”
Equally it is described in the atmel datasheet:
“The slave can extend the SCL low period by
pulling the SCL line low. This is useful if the clock
speed set up by the master is too fast for the
slave, or the slave needs extra time for processing
between the data transmissions”
Because of that I concluded that the Atml128-I2C components support this
mechanism
but now I’m not sure if it works fine.
Have anybody successfully communicated with an i2c sensor
that slows down the master clock with this mechanism?
@michael
Yes I think it is a related problem.
If I don’t get it to work with the standard tinyos components I think
bit banging will be the next step.
Are there any sources? Can you give a hint?
Best regards
Sebastian

Packet.getHeader() or some such method -- I don't use that

a cast and structure copy like this:

be a pointer passed in to your function from the message

One of the features of the Mote-PC communication is that the RSSI value is not included... On one hand it makes sense because that channel doesn't have a radio strength, but on the other, it causes lots of grief because folks want to see the strength of the signal received at the base-station, which is I presume what you are trying to do.

Sorry, but I can't help much further. My assumption is that Listen should be able to connect to external network ports, because it can do that with SerialForwarder. I know that SF has a quirky message format that needs a preamble character of some kind -- I think more like Telnet. First I would make sure that the leds are blinking on both your motes.

On one hand it makes sense because that channel doesn't have a radio strength, but on the other, it causes lots of grief because folks want to see the strength of the signal received at the base-station, which is I presume what you are trying to do.

Re: [Tinyos-help] Error while running net.tinyos.tools.Listen -- URGENT
It's a little unclear, but I'm going to assume that your point 2 means that you have installed Basestation on the mica2 that is plugged into the host computer. And further that you are seeing leds blink as one would hope... Then, the error you are getting indicates that Listen is expecting to connect to a network port, usually the SerialForwarder. This is the default behavior, but I always recommend just forgetting about SF and going direct, as it were. To connect Listen to the actual input port you need to set use something like -comm serial@COM1:mica2 where COM1 is the I/O port your mica2 is plugged into. You can also set the same string in a MOTECOM environment variable and not have to bother with it on the command line. Probably searching for MOTECOM will turn up some better advice.

Re: [Tinyos-help] Question regarding interrupt in Tinyos
Just for reference
Moteworks uses TOS1 which has different functions than TOS2
for doing everything useful.
That's one reason I stayed out of the fray...
but it is interesting that the interrupt number seems to be
mixed up between major versions. I wonder if it has to do with
the mica boards using a different numbering scheme than the
actual atmega manual for their hardware interrupts?

Hi Micheal,
Thanks for your reply. Actually, I am working on the tone

The following is my original code for this part, and I can see
that the interrupt is coming continuously. But when I probe the

fine. I suspect the interrupt part is not working fine.
By the way, I am using the environment of Moteworks downloaded

Re: [Tinyos-help] Custom modules.
The doc/tutorial describes how to do this with the config file. For a simple example, I think the Blink demo app has a config file that links in a couple of external modules. Or look for an app that has multiple .nc files (in T1 SimpleCmd has more than one source file) and see how it works. MS Jude Allister wrote: I have created a module that provides 3 interfaces.

Re: [Tinyos-help] TelosB Digital Output
Once again, here's my cheatsheet for the TELOSB I/O: http://www.etantdonnes.com/Motes/TMOTEpins.txt You can use any of the I/O pins for digital output, but avoid the I2C ones as they are shared with the radio. If you need to drive more than 10 or 20mA you should use a common emitter transistor follower, or if you've got a few outputs, chips like the ULN2803, google will be your friend there... They complicated the methodology of accessing the I/O in T2 and I only use T1. I think there is a component called MSP430GeneralIO or something like that for such uses. MS Eric Decker wrote: You need to find the telosb schematic and see what pins are brought out to a header. then find the msp430f1611 manual and bone up on how to use the digital i/o pins.

Re: [Tinyos-help] Sensing humans?
What you probably want is a PIR sensor (Passive InfraRed) like those used in motion sensitive porch light fixtures. Here's one example: http://www.sparkfun.com/products/8630 Note that they detect low-freq IR (around 10nm) which is what mammal bodies radiate, and they need a differential signal from motion so if you stand still (or wear a heavy parka) they may not fire.

Re: [Tinyos-help] Porting c code with nc one
I don't know of any micro-controller that has floating point hardware support. Are there such? The telosb MSP chip doesn't even have int multiply or divide instructions. The mica Atmega has an 8-bit multiply but no divide. With you, I always recommend fixed-point math. MS Sergio Valcarcel wrote: Hi Malissa, Depending on the platform you are using, your CPU may accept float or even double numbers. Also, depending on the architecture float computations might be accelerated with dedicated hardware or not. So the main points you have to verify is whether the extensively use of float operations will decrease the overall performance of your system. Of course, it is not the same to compute a numerical integration than to average two numbers... Another main point is the memory footprint. Float numbers typically could use 4 bytes. So you must take care of how much available RAM you have for your application. A final concern is that you can not use network data types (i.e. nx_struct) for communications since there is not defined a nx_float type. The other option, instead of using floats, could be to convert to integer, scaling as many decimals you want. For instance, 165.32 could be converted to 16532 (remembering that it is multiplied by 1e2). I hope it helps!

But it does do 16 bit integer Add and Sub so that's something... Therefore you need to be very careful with your math, and possibly hand-asm-code the inner loops. Also access to the external EEPROM may be rather slow, you should look into comparing the speed with the internal Flash memory for your image storage. Probably transferring larger blocks of data from ROM to RAM will help a bit too.

Re: [Tinyos-help] Pinouts of a TelosB SPI bus
hmmm...I haven't used SPI, on anything actually, but it looks like they did not bring all the signals you need to the I/O headers. According the the MSP430 Users Guide, I think you need SOMI0 which is named RADIO_SO on the schematic. You do get access to SOMO0 and UCLK0 as RADIO_SI and RADIO_SCLK, and I think you can use them for I2C, but there's not enough wires for SPI. I believe, from a quick glance at the spec sheet, that an internal UART is used to do the actual comm but the I/O pins are those of the RADIO_* variety. The CC2420 radio chip interfaces via SPI so you would need to do arbitration in any case. MS Marcelo Coelho wrote: Thanks for the quick replies! From what I understood, the SPI functionality is provided by the UART0 tx/rx ports and the I2Cclk (for clock source) and I2Cdata (for the slave select) in the 10pin expansion header.

Re: [Tinyos-help] L operator in timers
You forgot to mention that big-endian numbers are
MUCH easier to read in hex, and even octal, dumps...
I rue the day intel decided to one-up motorola and
go little-ended. Computers will never be connected
to one-another after all... Between that and the
incredibly stupid p.match over CR/LF I'll bet the
world GDP has been dinged by at least 10%.
Given that the hardware message headers are NOT
nx_ types and that there is (in all cases?) some
kind of translator between TOS and e'net, IMHO
it is just-one-more-confusion to add big-end
numbers into the mix.
But back to TOS... One possibility is that the Timer
does not really use a full 32 bit value. Both atmega
and msp have 16 bit counters -- maybe there is some
software foo to extend that by counting the counts --
so a mis-aligned number _might_ wrap around and end
up setting a crazy count value.
Your experimental protocol seems to be the best approach.

It made sense because big endian network order and big endian puters

Re: [Tinyos-help] Loading / saving a array of uint8_t at micaz/iris nodes
From my reading of the referenced page it looks like the xml file is used to define storage areas -- like files -- in the external EEPROM, but it doesn't address initializing the contents prior to running your program. You could implement a message to send and store your key. I don't know if there is any erase of external EEPROM done when a device is programmed, so the contents _might_ persist across new downloads and thus you would only have to do the message thing once. Another possibility is that there is a small internal EEPROM area on each controller. In T1 one accessed this using the InternalFlashC component -- which has probably changed names in T2. This memory _is_ erased but can be initialized at download time. I don't think TOS has implemented any method to do this so you would have to dig through the controller and download utilities to figure out how to do it. MS Markus Niedermann wrote: Hey!

What I meant by reset(10) was to send a literal value
as an arg, rather than getting it out of your message.

I bet you are right saying that the app_period is not reconverted to the
right byte order. it would explain why the timer fires in few millisec cos I
usually set the app_period between 1 and 30
btw, what's reset(10) ? is not a Timer command, isn't it?

Thanks a million Michael
there still is something that doesn't work:
if I do:
call MyTimer.startPeriodic(1024L * (uint16_t) (sync_msg.app_period));
where 'period' is a 'nx_uint16_t' inside the struct 'sync_msg'
everything works fine
on the other hand, if I use a function like:
reset((uint16_t) (sync_msg.app_period))
...
reset (uint16_t period){
call MyTimer.startPeriodic(1024L * (uint16_t) period);
}
the timer goes crazy
any idea why? am I doing something wrong casting the value?

Hi,
An easy question:
What the 'L' stands for when assigning the period to a timer? for example
call MyTimer.startPeriodic(1024 * 10L);
it starts a periodic timer that fires every 10 seconds but what's the
meaning of 'L'
I couldn't find it in google...

Re: [Tinyos-help] What is the maximum speed LED can toggle?
The usual thing would be to have a Timer post a send() task, and use a busy semaphore that is reset in sendDone(). Then you only need one global message buffer. If it was the receive side that hung up I would look at how you free the internal receive msg buffers. But it might be best to post your code...

Re: [Tinyos-help] Measuring different dynamic properties
There {is,was} a stack trace module, maybe you can find
it by searching on this list. Since there usually isn't
any dynamic memory allocation, memory usage is probably
no more complicated than looking at the compile output.
Dynamic power consumption would be interesting but you
need to put a current monitor in-line with the battery,
which requires a bit of hardware-foo. Probably just a
few resistors going to an ADC input but I'm not sure
about the range you would be able to resolve. I have
such a thing on my robo-cars, but use an op-amp and
a completely different power scheme.
I've sometimes puzzled over making some kind of
CPU monitor. I think one could put a counter in the
task scheduler to measure how long the controller
sleeps on it's daily rounds. But that's about as
far as I've gotten with it

I was also thinking of maybe using the system time of the nodes to time how long a signal took to travel between them but I figured that with the time to send and the turnaround time of the message in the other node this would be a pretty inaccurate way to do it. Is that even worth trying?

Re: [Tinyos-help] Adding precision to sensor data obtained
Pretty much all sensors readings on TOS devices are integer values directly from the ADC -- some few, like Voltage, may be may be mangled for range and level but are probably also ints. IIRC the telosb has a 12 bit converter so you should have 0-4095 as your values, which is a resolution of about .00025 per bit. You may convert that to floating point to about 4 decimal places if you like.

Re: [Tinyos-help] Adding precision to sensor data obtained
Assuming that the readings you are getting are, as I suggested, the raw ADC values from 0-4095 you can convert them to a voltage by multiplying by the ADC's reference voltage -- nominally 3.3v. So a 0 value is equal to 0 volts and a full scale 4095 value is equal to 3.3v. The reading you get is some fraction in between those: (value / full-scale) * refVolts example, if your value happens to be 2000: (2000 / 4095) * 3.3 == 1.6117 volts I would take the last couple digits with a grain of salt because the system is usually pretty noisy, and I'm not really bright enough to figure out if the theoretical precision is 3 or 4 decimal points anyway. Now your sensor may need some calibration and scaling so the conversion you use will probably have a form like (Mx + B), where M is a scale factor and B is an offset, both of which you might derive from spec sheets or brute force measurements. What are you sensing anyway? MS Mayank Gupta wrote: Thanks for the help Michael. But again I am not really sure how to do that. Can you refer me to some tutorial or reading where I can see how to actually code it.. Sorry but not really getting it.

Re: [Tinyos-help] Using UART and Radio in MicaZ on MoteWorks
The MultihopMsg struct contains: uint16_t sourceaddr; uint16_t originaddr; which you may be able to use to determine where the message came from. But you may be using the raw uart code to communicate between a micaz and some other device. Then you won't be using AM or MultiHop messages, so the interfaces will be different anyway. MS TJ wrote: I am using MicaZ with MoteWorks on Windows XP. I am trying to implement a network bridge where the mote has to communicate over UART to a attached device (a micro controller running some algorithms) and also communicate with other similar mote-device setups. By my understanding, there are two send interfaces which i can use for the wireless and UART channels respectively. But there is only one receive interface that has to handle both. My doubt is this - how do i differentiate where the packet is coming from if this is the case?? As MoteWorks seems very restricted in terms of the library files it contains.
