Can anyone recommend a PIC that is really compatible with the 16F628A that has 2 or more analog to digital converters? 10 bit is good. I am familiar with the 16F628A from Nigel's tutorials and have the main board, LCD, subroutines, etc. I need to monitor 2 analog inputs. It would be real nice if I could use existing circuits and just modify my programs a little. If there isn't a pin for pin replacement, what chip would be close?
