Please let me know I programmed a two PIC16F877A one is Tx and other is Rx but not doing good transferring of data to receiver. I checked both PIC16F877A with sample LED blinking code they both are working. PIC16F877A does not have internal oscillator I used 8Mhz Crystal with 15pF Capacitors. I am using Mikro C Pro for PIC compiler and using UART module. I check both Tx and Rx RF module both working good on Arduino but I want to make them work with PIC16F877A.
