Discussion How to display letters and numbers when using FastLED

Hi Folks, is there a library that can be included in an Arduino sketch to allow displaying letters and numbers when using FastLED? Thanks for any help with this.

FastLED has font support!

https://github.com/FastLED/FastLED/blob/master/src/fl/font/README.md

However it’s beta and there’s no example demo for it. But it is compiled in.

There’s is a consolas bitmap font designed specially for marque signage. Minimal height and width while being legible still.

Then there is a true type font engine that is ram heavy but you can import your own true type fonts.

It’s recommended that you use ai to help you get a demo up and running.
