3. Usage
3.1 Download and Install Thonny
- Download the Thonny installation package from: https://thonny.org
- After installing Thonny, while the power is off, press and hold the BOOTSEL button on the Raspberry Pi Pico. Use a Micro USB data cable to connect the Raspberry Pi Pico to the computer. The computer will recognize it as a RPI-RP2 storage device. Drag and drop the .uf2 file into the RPI-RP2 drive.
- Open Thonny. In the top menu bar, select Run → Configure interpreter.
- In the Interpreter field, choose MicroPython (Raspberry Pi Pico) as the interpreter.
- Set the Raspberry Pi Pico's port (COMx, where x is the port number recognized by your computer).
- Then click OK to save the settings.
3.2 Demonstration Code
Open the directory where the demo files are located and upload the example program to the Pico.
Click the "Run current script" button or press F5 to run the current script and observe the LCD screen.
When the display enters the button interaction interface, you can press the buttons on the board to observe changes on the screen.
