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.

Hi,
I'am working on acoustic sensors available with SBTv80 attached to TelosB
mote. The main objective is to process acoustic signals at very high
frequency of around 8-10 Khz for foot step detection. At present we are
using TinyOS-1.x with millisec granular timer to drive the data collection
Dear TinyOS,
I am trying to run the High Frequency Sampling program and have been
following the README. When I get to the command: java Sample 200 2
I get the following error:
-- Capture Output --
C:\Program Files\Crossbow\Crimson\IDE.bat
Did you run the whole jmakefile in the HFS directory?
It generates a bunch of app specific message classes,
but I'm not sure that is the real problem...

In general you can only expect about 100 TOS messages per second
in the best case. If you are trying to send more than that you
will loose all the overflow. You can aggregate multiple data
samples into one message but that still gives you (with a 30 byte
payload in each packet) only about 1500

You don't have to disable MOTECOM, you need one setting for SF to get
to the serial poet, and then there is a setting...probably in the
tutorial...that allows programs that use BuildSource to attach to
the enet

Title: Re: [Tinyos-help] High Frequency Sampling - Sample.class run error
Its not in the code.
Wheni compile the code, it compiles successfully. However, after i upload
to the motes and run the Sample.class program, the program runs and then after a
while(for like 2 seconds),message comes
ted by the readme file. The error is that it can't find a platform specific version of TOSMsg. Could anyone tell me how to resolve this error?
Thank you and regards.

I am currently trying to run the High Frequency Sampling program in the

The first problem is simply that you have overwritten the classpath
that contains the tools/java files so it can't find MessageListener.
This is a red herring, so stick with the second java invocation.
The real problem is in your second example where, apparently, serial-
Forwarder isn't
