Topic: I2C LCD/KEYPAD from Modtronix (Read 574 times) previous topic - next topic


Has anyone managed to get the Modtronix LCD2S (LCD/keypad module) to work using I2C?

I can write text to the display OK, however reading a key press is a different story.  I would appreciate any sample code that maybe out there, that may provide a hint on how to read key presses.  The pdf datasheet for the device is not that helpful.


Hi - Can you post your code and tell me about your wiring?   I can even get my display to work at this point....

See here on the forum for my issues:



Hi BlackJack

I will post my Modtronix wiring in a couple of days.
