TFT_eSPI VS unimatrix

Bodmer's TFT_eSPI is a graphics library for drawing to various displays, like the ILI9341, which is supported. It can be used with the Arduino IDE to program a Pico to interface with an ILI9341 using SPI, 8 bit parallel or 16 bit parallel interfaces.

For example, the electropeak link you posted showed a TFT LCD with the ILI9341 chip, and if you are using the TFT_eSPI library, this file needs to be configured https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setup.h , the default configuration looks correct in this case.

My favorite Arduino compatible graphics library is https://github.com/Bodmer/TFT_eSPI

I was under the impression that since this display uses a ST7789V, I'd be able to use the TFT_eSPI library which has support for this controller with ESP32 board. Is that a correct assumption on my part?

Looks like it doesn’t run cmatrix but you could recreate the effect with circuitpython. It may not be the easiest but it will be the cheapest option. There’s a Python version of cmatrix called unimattix that you can potentially start from. https://github.com/will8211/unimatrix/blob/master/unimatrix.py

Cmatrix but 10x better: https://github.com/will8211/unimatrix

There is also Unimatrix https://github.com/will8211/unimatrix https://youtu.be/TkZAa0uoFE8

I find unimatrix to be much better than cmatrix (you can even alias cmatrix to unimatrix -n -s 96 -l o in order to have it look like cmatrix.
