Anyone using CMSIS? How to get started?

Ahhh... yes.

I now realize that ASM is just assembly language. I believe the TLA (Three Letter Acronym) I meant to use was ASF... one letter makes all the difference ;).

I've found this reference for ASF which I'm hoping will be very helpful.

Thanks for the input. I'll keep you all posted.
