# Adalight-FastLED
|
|
|
|
|
|
|
|
## Synopsis
|
|
|
|
This project modifies the Adalight protocol to use [FastLED](https://github.com/FastLED/FastLED) ([fastled.io](http://fastled.io)). This expands Adalight to, in theory, work with *[any supported FastLED strip](https://github.com/FastLED/FastLED/wiki/Chipset-reference)* including WS2812B (aka Adafruit NeoPixels).
|
|
|
|
In addition to ambilight setups, the protocol can be used to stream *any* color data over serial from a computer to supported LED strips.
|
|
|
|
For this sketch to work, you'll need to have a copy of the FastLED library. You can download FastLED [from GitHub](https://github.com/FastLED/FastLED) or through the libraries manager of the Arduino IDE. This program was writen using FastLED 3.1.3 - note that earlier versions of FastLED are untested and may not work properly.
|
|
|
|
## Basic Setup
|
|
|
|
Open the LEDstream_FastLED file in the Arduino IDE and customize the settings at the top for your setup. You will need to change:
|
|
|
|
- Number of LEDs
|
|
- LED data pin
|
|
- LED type
|
|
|
|
Upload to your Arduino and use a corresponding PC application to stream color data. You can get the Processing files from the [main Adalight repository](https://github.com/adafruit/Adalight), though I would recommend using [Patrick Siegler's](https://github.com/psieg/) fork of Lightpacks's Prismatik, which you can find [here](https://github.com/psieg/Lightpack/releases).
|
|
|
|
## Additional Settings
|
|
|
|
There are additional settings to allow for adjusting:
|
|
|
|
- Max brightness
|
|
- LED color order
|
|
- Serial speed
|
|
- Serial timeout length
|
|
|
|
There are also optional settings to clear the LEDs on reset, configure a dedicated ground pin, and to put the Arduino into a "calibration" mode, where all LED colors match the first LED. To help with flickering, the option to flush the serial buffer after every latch is enabled by default.
|
|
|
|
## Debug Settings
|
|
|
|
The code includes two debugging options:
|
|
- DEBUG_LED
|
|
- DEBUG_FPS
|
|
|
|
`DEBUG_LED` will turn on the Arduino's built-in LED on a successful header match, and off when the LEDs latch. If your LEDs aren't working, this will help confirm that the Arduino is receiving properly formatted serial data.
|
|
|
|
`DEBUG_FPS`, similarly, will toggle a given pin when the LEDs latch. This is useful for measuring framerate with external hardware, like a logic analyzer.
|
|
|
|
To enable either of these settings, uncomment their respective '#define' lines.
|
|
|
|
## Issues and LED-types
|
|
|
|
I've only tested the code with the WS2812B strips I have on hand, but so far it performs flawlessly. If you find an issue with the code or can confirm that it works with another chipset, please let me know!

## Credits and Contributions
|
|
|
|
Thanks to Adafruit for the initial code and for developing the Adalight protocol. The base for the original FastLED modifications is [this gist](https://gist.github.com/jamesabruce/09d79a56d270ed37870c) by [James Bruce](https://github.com/jamesabruce). Thanks James!
