I did a serial IR App with the internal RC, and I ran into problems. I would get it working, and then come back the next morning and it would be off (like interpreting a 1000 as 0100). When I switched to an external resonator, everything worked fine.=20 That may have just been my crappy code, though. I am currently doing an IrDA app with the internal RC, and it is completely solid. My code is much better this time. Alex -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
