Hi all:
Now, I’m using the expansion connector of Tmote Sky to record same data of
sound. But I don’t know haw to set sampling rate of ADC.
Now, I’m using the ADCC.nc(/opt/tinyos-1.x/tos/platform/msp430) to get
data. I call ADCControl.setSamplingRate(TOS_ADCSample120us), I think it may
work. I use the timer with calling TimerJiffy.setPeriodic(4).Whenever it
fired, it will call ADC.getData(). I think the sampling rate of ADC is
8.333kHz(1/120us), but I use the function of MATLAB sound(wave,8333), I get
noise only. Using sound(wave,2000), however, I get the sound with some
noise. It must be that my sampling rate of ADC is 2kHz now. But how I set
sampling rate of ADC to 8kHz?
Thanks,
Gao Bo
