Wireless control of Led matrix using Teensy 3.0 and adafruit cc3000

This is a small project to control an led matrix using wifi, set up to go over a local router. The idea is simply to have a system whereby the led matrix will play animations from software running on a computer that is further away from the led matrix, or where using cables is not wanted. The set up currently works for an array of 8 by 30 leds and uses the freeware pixelcontroller software:


The test ws2811 led array running pixelcontroller output

The hardware components are: Teensy 3.0 microcontroller, CC3000 wifi breakout board from Adafruit, 8 x Ws2811 led strips

The software uses the OctoWS2811 led controller software to allow the Teensy3 to drive the data to the array quickly, and the CC3000 software for the breakout board, so that the Teesy can talk to the wifi module and connect to the wireless network. links to follow.

  1. Hi there, did you end up posting your code for this? I’ve got all the parts and would love play around with this :)

    • Hi, yes, you are right I didn’t post the code. I ended up going with a different approach in the end. I will dig out the ino file and send it to you. I have no idea if it will work with the new arduino IDE and the changes to the Teensyduino IDE. It required some changes to the library files in order to change to buffer sizes.
