I need to enamble any type of PIC ( I have the 16F876) to use Manchester Modulation to transmit voice singls over a twisted pair cable and use another PIC to demodulate the signal. 1. How much of this proces can the pick perform? I know you can use it for ADC, but what other parts of this processs can the PIC perform? 2. Is there code already written? If so could somebody help me out? Any Help would be greatly apperciated!!
