Re: NEW: PIC for controller?

Hi Larry,

Well, sounds like more reason to go the Mathis route!

16F627 or 16F628's have some interesting features too. I wish I had
more time for the PIC stuff. I have some 'C' code I'd like to stuff
into the 877's. With FP. That might be a chore! But if it works...

Looks like I need another update to the CCS 'C' compiler too.
