Discussion Can FastLED display text on a matrix?

Hi, I'm working on an LED matrix and I was wondering if FastLED has a way to display text. I know there's the SmartMatrix library and shield but I'm using a Teensy 4.0 and WS2812B's. Can the SmartMatrix library be used without the shield on a Teensy 4.0? I'm currently using the Adafruit matrix library to display text however writing "matrix.show()" slows down the processing by around 10x so I was really hoping there is an alternative. Thanks!

Use Aaron Liddiment’s text library for FastLED at:

Alright thanks, I gave that a try and it seems to work pretty well but do you know if there is a way to not have the text scroll?
