Hi, I am trying to get rs232 communication to work with Microchip C18 using a PIC18F452. I have connected a character LCD module to my 452 and manage to putput anything I wish on the screen. I have looked at the little documentation / information I could find on doing rs232 to a computer with the 452 and although I have managed to do it previously with assembly language I am yet to get success with C18. Can any of you bright people drop me an example of an interrupt driven piece of code that received a character at 9600bps and bounced it back to the computer? It will really be of great assistance to me if you have the time.
