Can somebody help me to write a C program(PIC16F877) for transmitting three 8 bit data via a 4 bit wireless transmitter module to be read by the reciever module to a pc thru rs232 connection.

Send 4 bit data twice on two variables, in your receiving program rotate left ( A = A << 4) first variable then OR with the second variable (A |= B),
A now contains the original 8 bit data.
