Try running at half the speed (8.7 KHz) to see if that works. Your Basestation also needs to be special, use the one we have on our website (it needs 125 kbps UART and a fastserial library). > Anyway, I wonder if the Atm128fastAdc library could be used on the > MDA300+IRIS platform knowing that IRIS has an Atmega1281 microcontroller > and the MDA300 has its own 12 bits adc chip and the actual MDA300 drivers > do not provide a ReadStream interface. The microphone is connected to the ADC of the Atmega1281. I do not know about your application though, so there you might have to use the 12 bits adc chiips.
