16F627A to 16F88 conversion problem

[Archangel]

16F648A uses the same data sheet (as the 627A) and has twice the code space.

Thanks for the responses. Ill figure out how to adjust my I/O pins (never done it) and im sure it would work fine.

I purchased 16F628A PIC's to replace the 16F627A that I was using. They seemed to have double the memory if I recall correctly (3.5kb as opposed to 1.75kb) and the 648's had 7kb of memory.

Did I miss something?

Then let's make the first one easy...

ANSEL = 0

Whenever you start using a new chip, the first thing you should do is look at the Comparator and Analog-to-Digital sections of the datasheet for the device you are using.

The different varieties of PIC's have many different ways of disabling the Analog functions, so you have to look in the datasheet to know which way to do it on that particular chip.

For the 16F88, the comparators are disabled at Power-Up.
For many other chips, that's not the case.
