This project has started to explore exactly this. I connected a Teensy 4.0 to a Waveshare 2" LCD Module with the Arduino_GFX library to drive the ST7789. As Button I use a Mini Pushbutton Switch.
| LCD | Teensy |
|---|---|
| VCC | 3V |
| GRD | G |
| DIN | 11 |
| CLK | 13 |
| CS | 9 |
| DC | 8 |
| RST | 7 |
| BL | 6 |
