Hi there again, Byron. I thought that I'd throw a little fuel on the fire, so to speak. Microchip's 10F322 is, in my opinion, one of the nicest little PICs=20 that I've ever worked with. Yeah - it has only 1- input-only and 3-=20 i/o pins but it has a LOT of really neat features in that little=20 package. I've actually written Microchip and asked them to do two=20 things: 1) Release an 8-pin (6-i/o) version; and 2) Add a comparator. I'd be even happier if they released a 10-pin version with all 8 i/o=20 pins made available . The really cool thing about this chip is that it has absolutely NO=20 RAM paging whatsoever. The first 64 locations in the RAM map are the=20 special function registers (ALL of them) and the last 64 locations=20 are user RAM. It also has some the niceties of the newer PICs -=20 including a LAT register for the port pins. I would be using these parts by the tens of thousands if only they=20 had a comparator. dwayne --=20 Dwayne Reid Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax www.trinity-electronics.com Custom Electronics Design and Manufacturing --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
