I Know. Ihave to write code for a Chipcon RF chip with an 8051 core. I called Melabs about it, and they said PICs are their "core" business. Try Bascom for the "other guys". The big problem is finding a USB or serial programmer that isn't $600.-!!. Anyone else have ideas for the 8051? Yes...I know this is a PIC forum, but until Microchip comes up with a transceiver that is as good as the CC1110 or CC2430 with built in processor, I have to stray :<(
