> BTW how many PIC-Lister does it take to sample 8 0..0.5 volt inputs? About 11 by my count: 3 to suggest code snippets 2 to come up with off the wall solutions that don't really solve the problem, but devolve into a discussion of sensing liquid levels in tanks. Scott to optimize the code snippets to half the original number of instructions. 2 more to complain that Scott should have included a few comments. James to complain that someone has already done it, is selling it at piclist.com, and we should be working on something more productive. Me to tell the orignal poster to RTFM, or complain about his email format. Roman to show how it can all be done with only $.19 in parts, and he'll have a version next week where the suppliers pay you. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com#nomail Going offline?
