Demonstration code for using a Raspberry Pi Pico with common TFT SPI boards.
Before building, you must fetch the git submodules.
git submodule init
git submodule update
I have it set up with the pin-out of the version that comes on a cheap Pico Breadboard Kit.
| Pin | SPI |
|---|---|
| 6 | SCK/CLK |
| 7 | MOSI/SDI/TX |
| 4 | MISO/SDO |
| 13 | CS |
| 14 | RST |
| 15 | DC |
I used Vlad Tomoiagă's library. It requires LCD_setPins(15, 13, 14, 6, 7).
For LCD_setRotation assuming the top of the screen is the top of the board,
| Value | Result |
|---|---|
| 0 | Top is right side of board |
| 1 | Upside down |
| 2 | Top is left side of board |
| 3 | Rightside up |
