view story

http://ubuntuforums.org – hello, im looking for a low pixel camera(something like 20-200x20-200) for my final project at school. the problem is that the lowest number of pixel i have found was 0.3 mp, and in order to recive a photo from that camera i have to build usb protocol interface with a microcontroller.. my teacher at school refered me to a program named OPENVC, he said i can install it somehow on the mc (microcontroller) and the usb protocols are inherent in that program.. some one knows that program and can help me using it?(i saw only computer uses of this program) another possible solution for that is av (Hardware)
