...where a bunch of geeks got together to make other people's ideas come to life.
Most monochrome LCDs use a 4-8 bit parallel bus for communication which uses up precious digital I/O pins on a microcontroller. This back pack has a built in Atmel processor programmed with all the LCD commands, which allows communication with the LCD using only one digital I/O. Simply solder this to the back of any HD44780 controlled LCD, and free up those precious I/O pins.
This backpack can even control back light brightness and has electronically controlled LCD contrast. For a list of serial commands, please reference the attached user manual. We have a video demo of this product as well as a short written tutorial.
