TFT Display ST7735 MicroPython
I got a cheap SPI TFT ST7735 Display module with SD Card reader off ebay, it had an unusual number of pins on the back.
It took a while searching about on the internet and some head scratching to find a library and work out what connected to what on the Pico.
This is what I found, and worked out.
| TFT Board | Raspberry Pi Pin |
|---|---|
| LED | 3v3(Out) |
| SCK | GP10 |
| SDA | GP11 |
| AO/DC | GP16 |
| Reset | GP17 |
| CS | GP18 |
| GND | GND |
| VCC | VBUS 5V |
Using that information I was able to put together this library based on a few others I found and a few test programs.

Based on the work from;
I have yet to try the SD Card functionality on the board, something to play with later.
