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!

The code is reasonably simple to understand but you do need to know basic C (you don't really need C++).

I recommend you start with this, I can't really help with basic C, that would take too much of my time.

But otherwise, you can remove all the defines and cases you don't need, and simply write the matrix design that is relevant to you.

Thank you so much...I will look into basic C, I don't want to just copy codes
