Pixel spark is a smart addressable LED (pixel) mapping software. With it, you can create a digital LED mapping, animations, and then compile your creations to arduino code.
Note
PixelSpark is a quick and dirty Python app I created a while ago. I keep it here for reference purposes, but if you need an open-source pixel mapping software, I highly recommend you check out XLights, which is pretty much what I wanted to recreate with PixelSpark
To install PixelSpark, just clone this repo and run python3 -m pip install -r requirements.txt
First, you need to create your mapping. To do so, click the "New light chain" button and click the start (input) and then the end (output) of your chain or strip. Then, tell pixelspark the starting (input) adress and the chain length.
Then, you can create an animation. For this, click on "New animation rect", create the start rectangle, and then move it to the animation end. Specify the animation duration and start timestamp.
Finally, you need to compile your animations to work on an arduino. Make sure you have the Arduino IDE and the FastLED library installed. Click on the "Generate arduino code" button, specify the max adress you have on your mapping, and press enter. The code is generated and copied to your clipboard.
You can now paste it in a new empty arduino project and upload it.
