In bulk, VGA cameras of this form are around a dollar. Essentially all of these interface in one way. There have as inputs: Clock signal - 6-20MHz or so depending. As outputs - D0-7 - a data bus that outputs all of the pixels. And 2 pins as an I2C bus, to setup registers and streaming. They may also have a couple of pins of GPIO, a chip enable, and a flash output. None can output video over I2C, you have to read it from the parallel bus at 6-20MHz - enough to readout the frame in 1/60th of a second or so. In short - you need a specialised camera input, with 8 parallel bits, and an I2C bus. You cannot use this form of camera without that. _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
