Jan 2014 - Dec 2022
An Implementation of Adafruit's NeoPixel Library for Particle devices: Core, Photon, P1, Electron, Argon, Boron, Xenon and RedBear Duo.
Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:2 reviews, 64 commits, 24 PRs in 9 years
Contributions summary:Brett primarily contributed to the implementation and modification of a library for controlling NeoPixel LED strips on Particle devices. Their work involved adding support for various LED types (WS2811, WS2812, WS2813, TM1803, TM1829, SK6812RGBW, and WS2812B2) and optimizing the timing for different bitstreams. These changes enabled compatibility with various Particle devices, and different LED strip products. They also corrected a memory allocation issue and improved the code for a more stable operation.
