PICO2 Arduino IDE Basic Project: Adafruit ST7735 TFT Display

This project provides a simple example for testing Raspberry Pi Pico 2 (RP2350) compilation and upload using the Arduino IDE, while implementing the Adafruit_ST7735 TFT display library.

Hardware Setup

To connect a TFT display to the Raspberry Pi Pico 2, use the following pin assignments:

#define TFT_CS   17   // Chip Select
#define TFT_RST  16   // Reset
#define TFT_DC   20   // Data/Command
#define TFT_MOSI 19   // Master Out Slave In (SDA)
#define TFT_SCLK 18   // Serial Clock (SCK)

Configuring the Arduino IDE

1. Install the Board Manager for Raspberry Pi Pico

• Go to File -> Preferences in the Arduino IDE.

• In the Additional Boards Manager URLs field, add the following URL:

  https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
  

2. Select the Raspberry Pi Pico Board

• Open Tools -> Board -> Board Manager.
• Search for Raspberry Pi Pico and install it from the list.

Flashing the Pico

1. Press and hold the "BOOTSEL" button on your Pico2 board.
2. While holding the button, connect the Pico to your computer's USB port.

Selecting the UF2 Board

• In the Arduino IDE, under Tools -> Board, select UF2_Board.

Compile and Upload

1. Once the code is ready, click the Verify button to compile your project.
2. Click Upload to flash the code to your Pico2.
