Pretty sure something is wrong in your setup, tested an AliExpress 240x240 st7789 LCD few weeks ago, worked perfect.

Better start with the existing demos, you have one for the 411 black pill.

Okay, I've managed to get it working. I still have some issues, but those are caused by my f***ed up cables.

But I did find one problem that you could fix.
The problem with me regarding the incorrect use of this library came from the missing LCD_Test function in the Library/LCD/lcd.c on this github.
The function is missing there, which is the place that I originally imported the lib from. Today I noticed, that it was present in the demo files. Thanks to this, I was able to figure out the correct usage and commands.
Thanks a lot for the advice. Sorry if I was bothering you.

The mistake is actually in LCD.h, LCD_test is just for the demos, an example to learn how to use the library, not part of it, so it will be removed.
Anyways this library is not in active development, I just played a bit with it during the pandemic.
