Hack A Day hands on SparkFun RGB button pad controller SPI

via Hack a Day: Parts: 4×4 RGB button pad controller SPI – Hack a Day.

Since I found it, I was really interested in the modular Monome RGB clone that SparkFun is selling for a ridiculous price.

However I was really disappointed about the lack of proper documentation and examples.

But guys at Hack A Day tested it, using their development board Bus Pirate universal serial interface

Must be noted that thank to this test SparkFun published a better datasheet.
