The 16F84 is more expensive and less capable than newer PICs that are plug in replacements electrically. It makes little sense to use it for new designs UNLESS you have a very specific reason for doing so. In the case covered by this thread one factor (regardless of what you think about its merit) was that the 84 is less likely to confuse beginners. Perhaps a better term than obsolete would be obsolescent. Russell McMahon -- http://www.piclist.com#nomail Going offline?
