It is relatively straightforward to make my own software work with the AN589 hardware. In fact, PICLIST contributor Mal Goris told me he had done just that. He may be persuaded to supply his source - are you listening Mal? Hiroaki Kobayashi has taken the C fragment presented in Application Note 589 and filled it out into a full program. You can find the source here: http://u2.alan.co.jp/~koba/pic/pgm84.c I've only had a quick look at this but one quirk is that it only loads the old INHX16 style hex files. Anyway, the source is there so you can fix that or not as you please. David -- http://www.man.ac.uk/~mbhstdj
