Lately, I've seen several questions that seem to occur over and over again in the Piclist (the one which caught my eye had to do with an I/O problem, and the answer was that the pin comes up as analog and needs to be changed to digital, but there have been other similar subjects). There are some really excellent faqs for those who are just trying to find out what it is all about. For example, http://www.voti.nl/swp/index.html comes readily to mind, as does the Piclist site (http://piclist.com/techref/piclist/begin.htm). But for the inexperienced (as opposed to beginning) PIC programmer/designer there does not really seem to be a suitable faq. I googled it and came up with the following: ... microcontroller-faq/PIC Subject: microcontroller-faq/PIC Maintainer: Tom Kellett Last Posted: 17 Jul 1995 11:43:21 GMT Posting Last posted 1995?
