Serial2Parallel Teensy Firmware – control thousands of LED modules

January 22, 2013 Respond

If you want to drive thousands of LED modules with a single Teensy at a decent framerate, you cannot use the Hardware SPI signal. Paul Stoffregen did a fantastic job with his Serial2Parallel Firmware. The idea is simple: send serial data and split it up into eight parallel outputs. This firmware was used to drive…
Kalikut NOW Stage Design

November 7, 2012 1

Some friends formed the band “Kalikut Now“. They asked me to help them creating illuminated letters for a stage show. They made eight 80cm high wooden letters with an acrylic front and did all the hard cabling work, I created the Arduino firmware and the Processing front end. I use a Teensy board, they provide…
LPD6803, SPI and long distance

March 15, 2012 2

I want to drive several units (boxes) filled with LPD6803 LED Modules (8-14 Led modules per box). Each unit is connected with a 70cm, unshielded and non twisted cable. I used those modules in the past without problems in my PixelInvaders project, however there are no long cables involved. My new project looks like this:…
PixelInvaders 3D RGB LED Panels

August 10, 2011 1

After several month of working on my PixelInvaders 3D RGB Panels I finally reached my goal: a huge and easy to assemble RGB LED Panel. Besides the hardware, the control software was a big task. I created PixelController, a modular software written in Java and released as OpenSource on GitHub. The frontend is written as…
Serial Latency: Teensy vs. Arduino

April 29, 2011 23

Paul Stoffregen was kind enough to send my a free Teensy 2.0 sample board to analyze the Arduino serial latency issue – and this board is shocking small: We wrote a very simple firmware to perform some basic benchmarks – Paul wrote a simple c tool to measure the native latency, I wrote a simple…
