HexLight GUI - RGB LED controller, supporting advanced colour models.

Primary LanguageC#MIT LicenseMIT

HexLight GUI

Language: C# WPF (Windows Presentation Foundation)

An RGB LED controller, supporting advanced colour models. Compatible with Arduino-based RGB controllers (simple 4-byte serial packet format) and my custom HexLight hardware project (see jorticus/hexlight-firmware)

The application sits in your Windows system tray, allowing you to rapidly change the LED colour to suit your mood, whenever you want to:

It also has a control panel for more advanced control:

THIS PROJECT IS A WORK IN PROGRESS

But feel free to use it in your own projects!

It probably won't work out-of-the-box for you. So read the source code to figure out how to interface it to your hardware of choice. I've made the hardware control fairly abstract, so it should be simple to add your own controllers

Also experimenting with advanced colour models such as CIE XYZ, CIE xyY, Blackbody Temperature, etc. Do NOT assume my advanced colour model code works correctly! It doesn't, and I'm working on it.

If you spot any math errors, let me know!

Features

  • Easy to interface to arduinos through serial or a TCP socket (eg. TCP to serial bridge on a server).
  • Support for a custom 4-channel RGB controller based on a PIC32, through serial or USB-HID.
  • Modular controller architecture, making it easy to add your own controllers/protocols
  • Automatic device connect/disconnect
  • CIE1931 luminance correction! Maps raw RGB values to logarithmic human vision, so they appear linear. This is more accurate than gamma correction.
  • CIE XYZ/xyY models for device-independent colour control. Work in progress!
  • Custom C# WPF colour-picker controls (HSV colour picker, arc-slider, XYZ/xyY colour picker)
  • Custom Colour math classes

TODO

  • Implement XYZ/xyY colour picker
  • RGB+White colour driving model, for more accurate whites
  • Send device-independant XYZ values to the controller instead of RGB (RGB doesn't give any guarantees on what colour it will actually produce!)
  • Implement XYZ calibration on the controller
  • Colour presets
  • Blackbody temperature colour (hot/warm/cool)
  • Animation (Fade, cycle, strobe)
  • Sound reactive lights (as in my project here: http://jared.geek.nz/2013/jan/sound-reactive-led-lights)
  • Animations

Future ideas

  • Interface with f.lux
  • Automatically set mood lighting when watching a movie or playing a fullscreen game
