[Robotgroup] PIC bootloader from Microchip

[Doug Evans]

Paul,

I use MPLAB. Are you looking for ASM advice or just how to set up and use
the IDE?

Don't forget to download the free version of HiTech PICC Lite on the HiTech
web site. It's a very good product for the price!

Any chance of getting some MPLAB pointers from either Gray or Alberto? I'd
like to try it, but need some coaching.
