I'm trying to implement a simple 433MHz data link between two 16=20 series PICs. I need to send 4 bytes (before encoding) across this link. I've used the KeeLoq example receiver code (TB045) with a bit time of=20 800us and 8x sampling. On the transmitter side it's a simple bit bang arrangement, using the=20 data structure shown in TB045. The receiver sets the RxFull flag when subjected to enough data from=20 another remote control that uses your typical 145027 type encoding. I can't seem to figure out what's wrong and have been going around in=20 circles somewhat. Has anyone been down this road before?
