Yes IrDA can run on a Pic, however it takes refinements for timing. Let me know what you interests are. Kevin E.

I am thinking about using IrDA and/or USB to communicate with some peripherials possibly runing off PIC. Before I start designing the hardware I would like to play with IrDA and USB alone. I have a PC mainboard equipped with IrDA and USB connectors (pin headers). The problem is that I could not find any info about accessing those peripherials (BIOS support, I/O addresses, etc). What sort of hardware is necessary to make an IR link. Would just TX,RX diodes and couple of resistors do the job? Thanks for any help janusz
