Transmission of audio signal using ER400TRS transceiver(data control executed by PIC16F876)
Posted on 2006-04-14
my task is to program a PIC16F876 using C programming (ccs) to execute a bi-directional communication link using Easy Radio Transceiver (ER400TRS).
A simple microphone pre-amp connects to analoge input of the the PIC, ADC is carried out by PIC, result is transmitted to transceiver using (port RC 6)........THIS IS TRANSMIT SUB-ROUTINE
The transceiver detects RF data, downloads it in its internal buffer, alarts the PIC by lowering 'Busy line', PIC decodes the data and puts it on one of the Port B's which connects to a low pass filter for an analogous waveform before going to audio amplifier (output)
please help because my trails have so far produce no successful result.
