I thought that there was some consensus on disappearing the programming function. This then means that there is a programmer on the board which can never be touched by the user, so bootstrapping up from nothing is never a problem. I envisaged a surface mount 16F876 for this function, a bit like the ICD. Wether it would work as an ICD for an 18Fxxx series chip I do not know, maybe the answer is to see what is required for that and check if it is backward compatible to the 16F87x series. -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
