Hi bob - Yep, u r right. I guess what i meant was LANC doesn't look that much harder to do than RS232. As c/w USB ... 'nother story. :( At least that's how it looks to me. Last time I had a serious look at USB was maybe 12 month ago. MChip only offered a windowed USB pic back then and in any case USB looked like a //real// problem for a PIC. The trouble is, while reasonably hi-res (3-6Mpx) mid-range dig cams are dropping in price (to say $200 ->$400), all they appear to offer by way of interface is USB. There doesn't seem to be any simple way to operate them remotely, a-la RS232/LANC etc. On the other hand, I'm thinking it must(??) be possible to operate cams by USB - those el cheapo printer/scanners you can buy for <$100 all rely entirely on a USB interface. So what about digital cameras? Thoughts/ideas? Confused.Debbie :) --- Bob Axtell wrote: > > > LANC is the easiest to implement, but it is NOT RS232.
