I'm looking for code, pinouts etc for LCD matrix displays. Also, I'm looking for some good sources for the displays. What I have in mind, is for using a pic 16c57 for taking the 2of 8 binarie from a cd22202e dtmfdecode chip, and outputing to a serial e-prom and to output to the display. It then must be able to access the eeprom to get readback buffers. Also, I'd like to find out how to use a pic to output to rs-232c and parrellel. any help would be appreciated. John P.
