Hi Marco, As you noticed, the minimum voltage for a good running PIC16F676 is about 2.5V to 2.8V for 90% from a PIC16F676 I/P lot. If you have a "working" PIC...
The simplest way for AD reading on 16F628 is to use the comparator and internal "reference" module. I've discovered that some example on these theme written in...
... No, it causes lockout. And since power on reset requires starting from 0V, the PIC doesn't reset on later power up. ... Activate Brown Out Reset (BOR) bit...
