Maybe there's a clue there. > >Dale The xmitter circuit is on http://www.rentron.com/Infrared_Communication.htm figure 6. I do not think this is the problem. The rx circuit is an lcd hooked to a F84, I have used this plenty of times It works fine connected to my serial port on the PC. The only change I made was to disconnect the TX line and connect the IR unit (GP1U26X). Pin1 to the RX pin on the F84, pin2 to Vcc and pin3 to GND. When I make this change, the bottom line of the LCD starts flashing garbage, whether I am sending the IR ddata or not. My code only writes to the bottom line. When I disconnect the IR module and put the TX line from the PC the LCD display clears and displays any character I send properly. Any thoughts ?
