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.
