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 using ADC.getData and ADC.dataReady combination.
I have come across earlier posting on this topic in 2005 ( http://mail.millennium.berkeley.edu/pipermail/tinyos-users/2005-January/000878.html) wherein getContinuousADCData has been suggested, and it was mentioned that with 8KHz sampling the mote should be dedicated for acoustic processing only. In view of the above, what is the recommended practice to achieve high sampling rates so that other activities such as communication, signal processing are not disrupted ? Thank you Regards Kuldeep
