Is there a possibility to detect a tone with the microphone, by using a hardware interrupt?
I already tried it by using the interface MicInterrupt:
async event result_t MicInterrupt.toneDetected()
But this only fires in the beginning when the node is started...(I use MicaZ and the standard sensorboard)
I can solve the problem when I continuously sample (each timer tick) by calling MicADC.getData() and checking if there's a tone detected ( Mic.readToneDetector())...
But this is not really what I want...
I searched the mailing list already, there were some questions on this issue, but there hasn't been a solution posted ...
So, if anyone has a solution for it, it would really help me
greetings,
robin
