Re: [PIC] Seeking advice fpr 14-pin PIC

Hi there, Joel.

Many thanks for suggesting the 16f182x family.  It turns out that I 
have several ICD headers for both 12f1840 and 16f1829.  Although I 
have to rewrite the initialization stuff, I can debug using a PICkit 
3 and not have to re-assign pins for RA0 & RA1.

I will give this a try.

I can then either switch back to the 16f676 or drop in the 14-pin 
variant of the 16f182x family.

Everyone else: I am still seeking suggestions!

Thanks again!
