BeagleBone Black with LCD HD44780 in 4 bit mode

It works well. Good news the code is freely available on Github. But first a photo:

The LCD I use is LinkSprite 16 X 2 LCD Keypad Shield for Arduino. It's available at SparkFun (here).

The 4 bit mode used less GPIO on the BeagleBone Black than the 8 bit mode.

The BoneScript code on Github: only the LCD and the LCD and the buttons. Make good use of it!

I am currently working with an OLED screen. I'll keep you in touch.
