Hi David!
Thanks for your help!
I have one more question for you...thanks in advance!
I have read a post on tinyos-help about Ack in Broadcast massages: Should
software ACK mimic hardware ACK as much as possible and provide
acknowledgment for broadcasts as well? and your answer: SACK should
I was reading the tinyos-programming-manual. At the end of Chapter 6.0 there is
this little remark:
Parameterized interfaces arent limited to a single parameter. For example,
this is valid code:
provides interface Timer[uint8\_t x][uint8\_t y]
However, if I try this i get only a syntax-error.

Hi Romain
Sorry for my delayed response, I did copy tymo into my previous tree yes, but
have since located the files and removed them. Is there something else I
should have done?
Thanks

Hi all
im measuring the RSSI using RssiDemo(in tinyos2.0), I wanna change the
transmit power by wire the CC1000Control
so I add a line App.CC1000Control- CC1000ControlP; in SendingMoteAppC.
and add a line event void CC1000Control.setRFPower(uint8_t power) in
SendingMoteC
I know there are something

Hi Mates
I recently installed TinyOS 2.x under Ubuntu, per CVS and tried to program

I compiled the Blink Application in der tinyos-2.x/apps/Blink folder and it
compiled without problems.

It seems everything went alright - the data
Hi all,
I am using the SP03 text-to-speech synthesizer and I want to control it with
the MicaZ mote. The possible ways are UART and I2C communications. I want to
use the UART option, but the speed must be 38400 bauds, which does not appear
as a possible speed to be selected .
Is it possible

i have a question about the relation between the event and call

When did you checkout from CVS? A bug was introduced a few days ago
that made all ATMEGA based platforms unusable. Try updating from cvs
with 'cvs up -dP' and try again; the bug has been fixed.

According to my reading of the Examples of Baud Rate Setting,
Table 82 in the version of the ATMEGA manual that I have, the
UBRR value should be somewhere between 1 and 5, depending on
the crystal used and a divider setting. Not 23 as you have...
I don't have the will power to look up what crystal
looks fine to me...
Search out Phil Levis's NESC manual for mucho detail
on how to use the various TOS dialext improvements.
It might actually be on http://docs.tinyos.net/

Hi,
I found some articles about cc2420 data rate from mailing list.
Is it true that maximum reliable data rate is about 50kbps? (without any
interferences)
Actually I only achieved 30kbps, but I think it's because that I serialized
sending. (send - sendDone - send - .)
And I didn't
The raw data rate is 250 kbps. You'll never achieve this in any practical
application because of the CSMA channel sharing taking place. The biggest
impedance to throughput is clear channel assessments and the CSMA backoffs.
The acknowledgment wait period is another big delay. SPI bus speeds
I am preparing the code to make the conversion of the raw RSSI value
available in received message (indirectly a reading from ADC INPUT 0 - RSSI
MONITOR). Although, I am developing using T1 (TinyOS 1.x), I read the T2 doc
http://docs.tinyos.net/index.php/Rssi_Demo and noted the same thing I
You may get a more informed opinion, but my belief is that the
raw RSSI reading should track the battery voltage because both
the source and ADC reference are relative to the battery. This
would not be the case if the ADCref was regulated, but it's not.
So baring any non-linearities you shouldn't
A little asideyou CAN measure the REAL battery voltage on
the micas because they have a fixed voltage connected to
the battery measurement ADC input (at least the mica2 does,
I'm forgetting if the Z is the same now...). It's counter-
intuitive, but when you convert the fixed ref it's apparent
Michael,
I understood your position. It really doesn't make sense to take the battery
level reading for each RSSI related to each received packet.
That's why, in my program, I will send this battery level value only if
happened a level drop (battery) based on a threshold.
Considering your idea, I
hi all
i searched the previous list, The value of * *DCC2420_DEF_RFPOWER
corresponding to the minimum RF power is 3, and not zero. According to
the CC2420 data sheet, the chip has 8 discrete power levels: 0, -1, -3,
-5, -7, -10, -15, -25 dBm; the corresponding values of
DCC2420_DEF_RFPOWER are
Hi again all,

If someone could share a program which simply adjust the gain
(magnetometer or microphone) by I2C, on IRIS mote and MTS310, I would be
very very grateful (I'm on this problem for a week now, so I start to
depress).

No you don't understand my position. You will have to check
the radio chip specs to verify if the raw RSSI ouptut is
independent of supply voltage or not. I suspect the not part,
and thus made the assertion that you don't need to make
adjustments to the readings as the battery droops.
You could
Hi all,
Where can I find a detailed tutorial on TOSSIM for TinyOS2.x except for
this:
*http://docs.tinyos.net/index.php/TOSSIM*http://www.cs.berkeley.edu/~pal/pubs/nido.pdf
It describes how to inject packets but not how to retreive packets in the
python program.

I was finally able to solve the MsgReader issue as I was trying to build a

use the Listen tool and correctly see the Serial Frame. The problem was that my
