Yes I had a bit of a play with one - got it working sort of then lost interest, sort of. I think my code is probably very messy (lightly documented ?) but can send it tomorrow if you like. Was written for a 16C73B & used RS232 input from a PC . Will try & remember to look it up tonight Richard P Dear All, Is anyone used the PIC, like PIC16F84 or 16C84 to simulate the IR remote controller signal (RC-5) before (simulate the encoder)? As I plan to build a cheap, simple, just 16-key remote control, anyone has any idea and suggession for this design?
