[Tinyos-help] Micaz Mote interfacing with Beagleboard

[TJ]

Hey!!

I am using a Micaz Mote and i need to communicate over UART with a
Beagleboard-xM.
I've got the Mote communicating with a linux system.
I wanted to know what do need to install on the beagleboard to do the same,
as there are space constraints..

Thanks.

Always Yours

[Tinyos-help] Iris mote stops after a while (TinyOS2.x)

[John Yamamoto]

Hello,

I recently got some iris mote, so I was following TinyOS tutorials.  I was
following Mote-mote radio communication, and programmed BlinkToRadio.  I
built it, and installed on my iris mote.  It looked like it works for the
first couple of minutes, but it stops after awhile.
I thought I made mistakes in my program, so I used the one in tutorials
directory, but I still get the same problem.

I used printf to check where the mote stops, and found out that it stops
right after it checks the return value of Packet.getPayload, or when adding
info to the packet. (It changes every time.)

I am using Iris mote (XM2110J) with mib520 for the usb bridge.  My
TinyOS2.x is up to date with CVS.

Does anybody knows how to solve this problem?

Thanks in advance.

Re: [Tinyos-help] Iris mote stops after a while (TinyOS 2.x)

[Eric Decker]

I would say try again but use the current SVN trunk and see if it makes any
difference.

If memory serves, the CVS code is well over a year old.

We tried doing congestion signaling based on simple threshold on the number of
packets in the queue and packet forwarding delays when the bit is signaled. This
led to unstable behavior and we turned it off. It is appropriate to use this bit
for signaling but to use it properly you want mechanisms at higher layer.

This is very interesting and you should share the results.

Re: [Tinyos-help] Measuring different dynamic properties

[Michael Schippling]

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

[Tinyos-help] Measuring different dynamic properties

[swayanti das]

Hi All

I am trying to measure different properties of TinyOS applications and
TinyOS threded applications and have this applications running on iris
mote..
Can anyone help me with this.
I want to measure the dynamic properties like stack consumption, or real
time memory consumption, CPU used, etc..
I have tried measuring the power consumption of these applications, but I
need more dynamic properties.

Any help is highly appreciated.

Re: [Tinyos-help] tos-install-jni

[Michael Schippling]

Based on messages received here, that script only works
about 75% of the time... Search this list for various
pieces of advice about fixing it. I use a back rev of
the tos libs and install them by hand so I can't tell
you exactly what to do, but if you can find the getenv
and toscomm files you can just copy them to the right
places in your JRE.

Re: [Tinyos-help] Question regarding obtaining intermediate C code

[Romain Bornet]

Hi,

You can find the intermediate C code generated by the nesC compiler if
you build an application using CTP. After you compiled the application
you will find an "app.c" source file in the build/
subdirectory. This is the generated C code...

Let's say for example that you build the MultihopOscilloscope in the
apps directory for the micaz:

$ cd $TOSROOT/apps/MultihopOscilloscope
$ make micaz

The generated C code is in $TOSROOT/apps/MultihopOscilloscope/build/micaz/app.c

You will see that the generated code is rather difficult to read and
follow but you can find CTP related function rather easily.

If you are looking for other CTP implementations more easily portable
in plain C have a look at: http://sing.stanford.edu/gnawali/ctp/

Hope this helps
 Romain
