> Has the 16F819 got any problems that would make > me think about not using it in a A customer of me has a number of 819's (IIRC some 40) in a network in a greenhouse. I selected the 819 because at that moment it was the cheapest self-writing PIC. (They can all be updated from the central PC. Even with ICSP you don't want to crawl around a greenhouse updating 40 PICs on every software change.) Plenty of problems, but all atrributable to various greenhouse effects ;) Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: www.voti.nl consultancy, development, PICmicro products -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
