32×32 RGB LED matrix panel Minecraft

Minecraft1

Over the holidays, Adafruit community member “jillesdotcom” worked to tune Arduino code for the running RGB color on our 32×32 RGB LED matrix panels, and produced these fun Minecraft visuals. Shared here on the Adafruit Forums:

Had some fun coding the 32×32 RGB matrix on the arduino this Christmas

I rewrote the RGB (de)coding functions and created some constants to color a bit easier.

rgbcolor() uses seperate codes for red, green & blue e.g. 0..255 or 0×00..0xff
htmlcolor() uses a single (HTML) colorcode, e.g. 0xFF00FF

32×32 RGB LED matrix panel: Bring a little bit of Times Square into your home with this totally adorable 5 inch square 32 x 32 RGB LED matrix panel. These panels are normally used to make video walls, here in New York we see them on the sides of busses and bus stops, to display animations or short video clips. We thought they looked really cool so we picked up a few boxes of them from a factory. They have 1024 bright RGB LEDs arranged in a 32×32 grid on the front. On the back there is a PCB with two sets of dual IDC connectors (two input, two output: in theory you can chain these together) and 12 16-bit latches that allow you to drive the display with a 1:16 scan rate.
