OK then. From what I can see on the scope and the image data the PIC returned, it looks like the CCD is discharging before the PIC gets a chance to read it back. I bet this is down to reading two lines of image data, then blasting them down the RS232 link, then grabbing more. Unfortunately the entire image will take around 16k bytes, which is a fair bit more than the 1536 bytes of RAM the PIC has. It also seems the PIC doesn't have enough I/O lines to address a 16kbyte RAM, well, not with the camera connected anyway. Some days you just can't win. :-/ Later, -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem@philpem.me.uk | ViewFinder, 10BaseT Ethernet, 2-slice, http://www.philpem.me.uk/ | 48xCD, ARCINv6c IDE, SCSI ...
