HI folks,

I recently bought one of these in yellow and wanted to get it running with Parallax's P8X32A microcontroller (https://www.parallax.com/downloads/p8x32a-propeller-datasheet). I wrote a driver/object for interfacing with the display over I2C (tested ~1kHz-400kHz), but plan to try an SPI version as well. It includes demo code, as well (for the uninitiated, everything is written in SPIN - a language of Parallax's design).

I've put the code up on github for anyone that may be interested (MIT license) at: https://github.com/avsa242/nhd-0420 as well as a video of the demo code, for those that may not have a Prop:

Cheers, and thanks Newhaven for these nice display modules!
