PIc 16F639 AFE

The AFE front-end on this device really awesome. Download the docs & source code from
Microchip for their PKE system. Full schematics with source code to get you started.

I can't share what I'm doing with this at present since it's for someone else, but I can
tell you it's very simple with PBP, and pretty awesome stuff once you get the hang of it.

If you need transponder coils, check with coilcraft.com. They sell directly to the user, and
normally have plenty in stock. Get some fresh calculator batteries, and be prepared for a
lot of math..;o}
