I found the 8 zoom speeds, and a bunch of other things.. just transcribed my year old scribble notes so I won't lose them (included below). That's another project that is probably worth documenting - since it would let anyone figure out what _their_ camcorder does fairly easily. (would probably need a little more development since I used these really clever TI hex display LED modules - TIL311 I think - that have all the decoders and latches built in, but they're not easy to find, eat power and cost about $15 each... would be best to use one of the PIC with the LCD drivers built in...) I should probably go back and play a liitle more now that I'm more familiar with the various little symbols on the LCD panel. I didn't recognize some of them right off, so the notes are a little confused.... Oh well, time to give up for the day.... edc ----------------------------------------------------------------------------- This page has some LANC codes: http://home.t-online.de/home/mb.koenig/lanc.htm [jpb]
