Making our code run 45,000% faster - Fetch #7
We've been optimizing our embedded system for faster code so we could fix some necessary features. Most of the performance boost comes from upgrading from an Arduino Mega to a Teensy 3.6, but a lot of it is also down to doing some changes to our hardware connections in order to parallelize huge chunks of the shifting out process.
As a student-project at the University of Oslo, we have designed and built a massive ferrofluid-display with 252 electromagnetic "pixels". On Applied Procrastination we will share all the details of this project and hopefully inspire you to make something similar - or follow your own dream projects.
