This is done if _font_fill is valid: https://github.com/nopnop2002/esp-idf-st7789/blob/42705cd3a0c99f917f37920db310e5d22303b0e1/main/st7789.c#L751

The reset timing may be different for each TFT.

I think there is an electrical problem around reset circuit in the breakout without the CS pin. Perhaps the reset circuit requires a lot of current. I inserted a 100...

As you can see from the source, the usage of the BxCan register is different for each model. The code I provide doesn't work properly on other models. Even if...

as far as I know F103 and others are too different. They are almost different code. Check with my code. Almost impossible to merge,
