PlatformIO project, use VSCode + PlatformIO + ESP32 packages + Arduino to compile

Features

Serial interface for debugging via USB
HomeKit integration thanks to HomeSpan
Connects to pre-defined WLAN
REST API for pixel control and animation control
1 implemented animation
Brightness control
Current sensing, logged to serial output

Compile and flash

Use Visual Studio Code and the PlatformIO development environment to compile this project and flash it to the trixel controller. After installing the ESP32 platform within PlatformIO, all the tools should be present to compile and flash this firmware.

Connect with USB to the trixel-controller, which will provide power and can be used for programming.

Upload the firmware and check in the serial monitor that it is running.

How to use

Set up your trixels. How to do this is described here. If its your first time setup, it might be a good idea to start with a small, simple panel. You can always get more complicated later.

Connect via web (http) to retrieve web-ui for configuration and control.

You can also connect with HomeKit (Code: 11223344) to control the panel. HomeKit treats the panel as a light, allowing control of the color of all the trixels at the same time. You can't control individual trixels via HomeKit, use the web-ui for that.

You can connect to USB and use a serial terminal app to see debug output and monitor current levels if desired.

REST API

Call URLs like http://10.0.0.55/trixels/1?r=255&g=0&b=0&brightness=100

⚠️ Substitute your controller's IP address for the one used in the examples.

GET /trixels/{n}

Set trixels or brightness

Parameters:

n - trixel number (in path)
r - red, 0-255
g - green, 0-255
b - blue, 0-255
brightness - 0-255

Example:

http://10.0.0.55/trixels/1?r=255&g=0&b=0&brightness=100

{ "r":253, "g":0, "b":0, "brightness":100 }

GET /animation

Control animation
