# LED Mapper
Web App: [https://jasoncoon.github.io/led-mapper](https://jasoncoon.github.io/led-mapper)
An online tool to generate and visualize maps for irregular and/or gapped LED layouts, for use with [FastLED], [Pixelblaze] and other libraries.
Heavily inspired by the excellent [FastLED XY Map Generator](https://macetech.github.io/FastLED-XY-Map-Generator) by Garrett Mace of [Macetech] which in turn was inspired by Mark Kriegsman.
The difference with this tool is that instead of generating coordinates for any "gaps", coordinates are only generated for each actual LED. So if you had an irregular/gapped matrix of 128 LEDs in a 16x16 grid, this tool would only create coordinate maps for 128 LEDs instead of 256. This usually results in lower memory usage, but also generates coordinate maps for radius and angle.
Using [Google Sheets] to create a layout:

I used that to generate the mapping code for the pixel blaze by inputting the led numbers into a google sheets spreadsheet and then copying it over. It’s a really amazing tool
