I am implimenting IrDA on my current project and this was the way I decided to go as well. Use the scenix chip for the IrDA stack and use a PIC chip to handle the real work. Problem is that I have tried on a couple occasions to get hold of someone at Scenix to answer some very specific questions. It's been a month and still my E-mails go unanswered. Not a good approuch to ignore customers. Think I might try getting the PIC version working again. Anyone want to work on this together?
