    The code I posted above in this thread is for IR. If you study it you will see that the method is identical to Lester's.

    I have one 12F629 sending the 32 bit codes and another receiving the codes. Instead of IR transmitter and receiver I have the transmitter PIC connected directly to the receiver PIC. I do not have an IR receiver handy. However, I've used the same basic code in devices which did have an IR receiver.

    I quickly modified a simple test program written for other purposes to display the DEBUG output. See the attachment. You should see the same output ($50$AF$42$BD) every 15 secs) in whatever terminal program you are using.

    As for DEBUG, read the manual - it's similar to SerOut and SerOut2.

    You should be able to use my code merely by changing the GPIO.x pins to whatever RA.x pins you are using. I haven't used a 16F84A in ages so I'm not going to write the conversion for you.
