I started writing some programs to control the DRV8825 using a few small embedded boards I had lying around - the Metro by Adafruit and Arduino Uno both of which are based on the ATMEGA328P processor.  I went with these because I wanted something simple, low cost, and low power.

Getting started on the Arduino IDE was effortless. I also found an awesome tutorial showing how to map an existing stepper motor Arduino library to the DRV8825. Within minutes I've got a working example driving the LED (instead of the DRV8825 STEP pin) on my demo board. Pretty neat!
