A problem with writing code then moving on is that bugs never get fixed. In a production environment, we update code as production test and customers find problems. I think an ap note tends to be written, published, then never looked at again. The code pages at http://www.piclist.org are great since users can add comments. It might be kinda interesting to have a pic code wiki or CVS where users can contribute code, other users can comment on it, remove bugs, make improvements, etc. Harold -- FCC Rules Updated Daily at http://www.hallikainen.com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
