Hi,
I am using the MDA300 in order to acquire sensor data with a rate of 200Hz (At this moment I have as input a sinewave). In order to achieve this I have changed the XMDA300 Crossbow program in such a way so as the mote to read 22 samples and then send them in one packet. Also I have changed the following: >From XMDA300M.nc: - TIMER_RATE = 6ms - ANALOG_SAMPLING_TIME = 12 FROM SamplerM.nc component in the sensorboard/MDA300 directory: - TIME_SCALE = 10 (for resolution of ANALOG_SAMPLING_TIME equal to 0.01) - SCHEDULER_RESPONSE_TIME = 2 These are the minimum values with which the mote can work and get samples. However I cannot get clear a signal of even 30Hz. Does anyone know the exact meaning and functioning of the above parameters? Can anyone propose a combination of these parameters that could result in higher sampling rate? In other case, did anyone achieve a sample rate of 200Hz using other way (other driver than Sample)? Any help would be appreciable.
