although there are some distrubances in the measurement, one can

Hello
I'm working with a micaz and a micasb and I want to record sound and
voice with the microphone of the micasb.
I'm taking measures of the microphone in a high frecuency, but I don't
know how to convert them in a audio file.
If nobody knows how to do I will be very pleased.
Thank you and
First of all, if it's a digital picture you mean by image, a TinyOS network
is far from suitable for transferring large amounts of data. If you mean a
program image, there are tools that do such things. I got an impression that
you haven't read the TinyOS tutorials and documentation before
Tanks for your help Roman.
I will try this week again, set pState in MCUSleepC.nc, and then measured the
current.
Tanks again

Is there a schedule for the next 2.x release? There seem to be an aweful
lot of fixes in CVS.

I have managed to implement I2C communications between my ultrasound sensor and
Thanks David! Totally missed the blank. Works like a charm now.
BTW, I had another mistake in using the COM-port numbering, while
serial port should be specified as in the serial forwarder.

Assuming you have received and collated the data on a PC of some sort,
look into the java media lib/jars for ways to create standard audio
file formats, like .WAV or .AIF. Also some editing programs, like
Adobe Audition, allow you to import raw text files -- but I've not
tried it myself.

That's a hard one. The sampling rate gets you low frequency audio only.
Audio is not really a MSP430 function, and needs external A2D, or digital mics,
and data reduction at the mote before it will be practical.
I was trying to be polite...heh...
With the micas at least, you can sample at an early-telephone audio
rate if you can work out the timer issues (which the original poster
indicated was a fact). But you can only store a short sample period,
and then it takes _forever_ to transmit -- although a
That's a hard one. The sampling rate gets you low frequency audio only.
On the ATMega128, you can safely sample with setting the ADC prescaler to
5, which gives a sampling rate of 17723Hz (assuming the ADC clock freq is
7372800). Of course, you will need to make sure that interrupts are not

What I was thinking is that one could sample at around 6K and

quite adequate for voice...But I don't know if you could send

The script is looking for this file: toscomm-32.dll.
I renamed the /usr/lib/tinyos/toscomm.dll to

with which tos-install-jni).
Which rpm is responsible for the toscomm.dll file in /usr/lib/tinyos ?
