How do I control NeoPixel from FireStep?

FireStep allows you to set the level of the display using dpydl. The NeoPixel is very bright, so I use 32 as default level, but you can crank it up to blinding at 255. You can also set the display status with dpyds. I usually set it to 12 for camera lighting.
