Hi Hank. I will chime in and say I have no idea where to learn it formally. I learned from reading the datasheet. I started out on stamps, first a BS1, then right away went to a BS2. at the time I think they were $99 for a BS2. Well I almost rightawat burned an output and couldn't bear the thought of another $100 for a $2 chip. So that lead me to PIC's. internet was plain ole telephone for me at the time, so getting the DS for a 16F676 was a chore. I printed the entire thing and off I went. I remember I made 1 phone call to uChip support (yes they answered my question over the phone)

ASM is not that hard, it is just a pain at times since there is not really any powerful instructions.

I for one am more then happy to help if you want it, maybe in the off topic section? Just like any PBP program, you need to know what you want to do and you can get there. I am certain there are others here that can and prolly will help, so start asking questions and you will get there.
