LCD Module Interface with Motorola 9S12DP256 Microcontroller

diddy · Post by **diddy** » Mon Mar 20, 2006 11:19 am

Wondering if anyone has or know where I could find any c-code relating to interfacing a 20-character 4-line LCD display with the motorola microcontroller, that'd be very helpful.

I am also using a 3x4 matrix keypad to input data to the LCD screen / microcontroller...

Please help, thanks a lot!

Sorry can't help you, as it's not one of our products therefore we can't give you information that's 100% accurate... but from the looks of it, it is a HD44780 compatible display, so take a look online for some tutorials... for something easier from us, you might want to try using the LCD2041, it uses super easy to use serial interface...

Good luck.
