I wanted to know if I can hook up a optrix c-51505 2x20 display to a BS2SX. If so could someone help me in the process? No other components will be used so I know most all I/O pins will be consumed.

    From Optrix's website, the spec sheet indicates that this is the bare display without a controller. As such, it would need more I/O pins than would be available from a Stamp. If you buy a display with a controller like the HD44780 that they suggest, that combination should work with any of the Stamps and probably most of the example programs on the Parallax website for a parallel LCD display should work.

    Hello,

    If you connect the display in 4-bit mode it will take 7 I/O pins on the BASIC Stamp. You can find connection details at the following link. I hope this helps. Take care.
