Hi,
I recently installed TinyOS-2.0.2 on Windows/Cygwin. I have ported the Chipcon
hardware (CC2420DBK) in TinyOS and I am checking the applications one by one to
check the correctness of my port. I was trying the TestLocalTime, it compiles
and installs correctly and blinks the LED0. It also
Since I'm working on Tmote Sky (12 bit sampling resolution) I had a look on the relative datasheet at page 23.It says that Vcc= (sampledData/4096)*Vref*(2R/R) and sampling is done in the middle of 2 equal resistors between the Vcc and ground.So, from what I could understand Vref (a stable voltage
Dear all,
I'm trying to use a MTS310 sensorboard on a mica2 running a Tinyos 2
application but it doesn't work.
I did a first test using a Tmote Sky with Oscilloscope application from
tutorial and everything woks very well. So a think I'm going by the right
way.
I need to use Mica2 + MTS310
Sir,
I think we must create a board like the smiths-medical
have the is compatible also for telosB. It can detect
and output the pulse rate and the oxygen saturation.
Also we could add the temperature sensor in there to
have temperature reading to be send to the ADC port of
telosB. But the
This is good stuff. I suggest creating a link to this on
http://docs.tinyos.net http://docs.tinyos.net/ if it hasn't been done
already.

I haven't looked at the battery monitor on the tmote. There appears to be
an InternalVoltage module which may be the battery voltage. However
I would have to spend the rest of the day tracing through schematics,
code, and the MSP manual to figure out what they think they are doing,
which could
Well, I would start by looking at the specs for my sensor
to see what kind of signal it puts out. If it's an analog
voltage and it's in the 0-3v range you can just connect
it to an ADC input and start programming. Otherwise you
may need a resistor ladder to reduce the voltage or an op
amp to
What sort of functionality are you looking for? Retry calls to start

post a task until these calls return successfully?

Uh, the point is that SplitControl.stop should only return EBUSY if
the underlying component is in the starting state. So the question is

Can anyone help me by which simulator can simulate the code for telosb.

Hello again,
I re-read the code and see now that EBUSY should only be returned by
SplitControl.stop() on PowerManagerP if a release() command is issued before
a granted() is signaled, which I believe should not occur. And the stopping
condition variable prevents the EBUSY from being returned by
As the code currently is, you're right, if start or stop ever fails,
then there is a chance for lock up. Doing a task repost after
checking return conditions shuld fix this problem. As you say though,
if FAIL is returned indefinitely, then the task will be reposted
forever, but then again you've

Agreed, but what do you propose as an alternative then? The only one
I see is potentially exporting a new interface that a user can wire to
that lets them decide what should be done in the case of a failure.
Or maybe run in the loop a fixed number of times before giving up and

our group is considering to set a small system that can set a certain

the remote node can reset its light threshold to the new one.

The existing component implements the lightweight policy decribed
here, and I made a modified version that does an endless task loop
this morning. I can either check that one in as
EndlessRetryPowerManagerP or just leave it as is for now until a use
case for something like this comes up.

I think you should be able to use DMA under tinyos-2.x. The issue
then becomes a problem of processing all the data before the next
frame of data is available. You may want to look into using the
hardware multiplier.

I'm developing an aplication with Tinyos and Micaz.
So, What's the best version to start my application, v1 or v2?
Because the Moteview/Moteworks has installed tinyos 1.x (cygwin).
