Hardware Hookup

Here are the pin connections between LED panel connector and the Teensy 3.1:

Panel connector pin numbering convention: Pin 1 is top left (R0), pin 2 is to the right of pin 1, pin 3 is below pin 1, pin 4 is to the right of pin 3, etc. Pin 16 is the bottom right.

And for handy reference, here's a pinout chart for the Teensy 3.1:

When connecting into the ribbon cable connector, pay attention to the notch that signifies polarity. When looking at the cable with the notch facing up and on the left side, R0 (pin 1) should be at the top left.

Red, green, and blue wires inserted into cable

Both red and blue wires should be on the notch side, the greens should be on the other.

Your hardware hookup should look something like this when you're done.
