I'm a newbe to basic stamps and I have a 2p24 basic stamp. I·would like to run a graphic LCD·with a DS1302 and using a 74Hc595. I have a VK512ELYG 32x120 graphich LCD and the pin out on it. Can I hook it up like a 2x24 LCD or is there something special I need to do and which pin to hook it to. Thanks in advance . Skoogie

    You need to find out what controller your display uses. The Hitachi HD44780 is popular, yours could be different. The controller on the LCD will determine how to wire and communicate with the LCD.

    +The controller is SED1520F and there are 2 of them on the LCD.

    You should be able to use google to get information on interfacing with it, the SED chip is the second most popular (behind the Hitachi).

    What is it specifically that is confusing you? The text file of the pinout should closely match the pins on the SED controller, this should explain most if not all of how to connect to the LCD. Look for BS2 code on how to connect a character based LCD to the stamp (such as the one you can connect to the BS2p40 board). This will give you a basic understanding of how to interface with it, then analyze the documents for the SED to see what differences there are. I have no time to help you develop code, the end of the fiscal year is quickly approaching and I will dissapear from the forums until after October 1st starting within the next day or two.
