Has anyone made use of the NEC UPD791 4096 element CCD sensor I have seen advertised in CCI and other periodicals? Are interface information and/or application notes available from besides the company? I myself am thinking about building a scanner to digitize all the articles and newspaper clippings I've accumulated over the years to reduce the fire hazard from all the paper. I'm also looking for examples on OCR, but that's outside the scope of this newsgroup.

Do you mean besides NEC ? NEC publishes info on the chip WITH circuit examples. Basically all clocks to the chip are 0 to 12.0 volt control signals - two phase. [You can use DH0026 level converters to convert from TTL to the correct clock levels.] Supply voltage for the device is 12.0V. As far as theory goes I would suggest getting a TI, Fairchild or Thompson CCD data book - they have good overviews of CCD operation... # Mike Gore, Technical Support, Institute for Computer Research # Phone: 1-519-885-1211, x6205 # Fax: 1-519-885-1208 # Internet: magore@watserv1.waterloo.edu or magore@watserv1.uwaterloo.ca # UUCP: uunet!watmath!watserv1!magore
