I'm a univerisity student in China. And currently I'm doning a project on gunshot detection with wireless sensor networks. We are using MICAz and MTS300 as the devices. I met with a problem. The sampling rate we need is about 6k-8kHz. But the sampling rate of TimerM.nc is to limited and we have to deploy MicroTimer.nc. I'v already change the code of MicroTimer.nc so it's suitable for use in MICAz. I've integrated it into the application like XSensorMTS300 to replace the previous Timer. The yellow led does not act as what the codes act. And I set the maximun samples to 8000 and send the last sample. I rarely got the sample. Why?I add our codes to this mail.What should I do? I've attach our codes in this mail. Thanks!
For rates like 6-8kHz, on mica-family motes, I would suggest looking at the HighFrequencySampling application (I haven't tested it on anything but mica2's, though). On micaz's, it might be possible to sample&send rather than sample&store (but then again, the radio overhead might be too high).
