Hi,
I don't know why you want to use string but I don think that it is a
good idea.
If you want to use it for sending commands, I recommend you to use
numeric constants, this is faster, easier and it saves resources. You
declare them with enum and dont have to worry about their representation
Hi Jan,
Did you have the time to check my configuration in my last mail?
I still haven't found a way to resolve the problem with my adc sampling..
Thanks again

Hi Jan and John,
Thank you for your responses, I finally find where the problem occured,
it seemed to be a problem of buffer copy.
I fixed this while rewriting a large part of my code so I'm not sure
about this but apparently it wasn't exactly an adc problem but when I
handle the results and co

I'm working with telosb and I'm trying to find a solution to estimate

tried the TimerMicro but as i found after in the mailing list (here

Look at the datasheet

Then use the GeneralIOC component to use these port. Use the

Hi,
I put my loop into an atomic block and as you thought there is no more
jitter and now i can have 8.8us period.
But i dont know which interrupt occurs since my overflow event is not

something.
Thanks again

Hope it will be useful.

I want to compile code that i dont want to put in the original TOSDIR

Hi,
Im trying to use gpio to output a signal on port16 (GIO2) but I always
got 0. When using the exact same code on port 26 or 62 everything works
fine. I also tried to set the io function by the selectIOFunc() method
but nothing changed. I tried on differents motes (telosb / tinyos 2.x).
Why
Was an error on port number, correct port in 23 (CA0/TA1) instead of 16

Hi,
Is there a particular reason for the multi channel sampling methods to
be unavailable in the AdcReadClient/AdcReadNowClient/AdcReadStreamClient
whereas these methods are implemented in Msp430Adc12Impl. Is is for
portability?
I also found that no constant is available to use
Msp430Adc12Cli
Hi,
Thanks for all your replies. I'll sample my channel with the multiple
channel interface and see if i can have the frequence i need, around
1000 hz without dma. If i can't i'll try to add dma to improve speed.

The problem is the reference voltage. You are, I guess, wiring to

When i use the multi channel sampling component (like in the

I'm sampling channels INPUT_CHANNEL_A0, INPUT_CHANNEL_A1 and
