Python codes

Use in Windows

  • 1. Press and hold the BOOTSET button on the Pico board, connect the Pico to the USB port of the computer through the Micro USB cable, and release the button after the computer recognizes a removable hard disk (RPI-RP2).
  • 2. Copy the rp2-pico-20210418-v1.15.uf2 file in the python directory to the recognized removable disk (RPI-RP2).
  • 3. Open Thonny IDE (Note: Use the latest version of Thonny, otherwise there is no Pico support package, the latest version under Windows is v3.3.3).
  • 4. Click Tools -> Settings -> Interpreter, and select Pico and the corresponding port as shown in the figure.

  4. Note: You will be prompted to install the driver during the installation process, we can click Install.

Install Arduino-Pico Core on Arduino IDE

  1. Open Arduino IDE, click the File on the left corner and choose "Preferences".

  2. Add the following link in the additional development board manager URL, then click OK.
    https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json

    Note: If you already have the ESP8266 board URL, you can separate the URLs with commas like this:

    https://dl.espressif.com/dl/package_esp32_index.json,https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json
    
  3. Click on Tools -> Dev Board -> Dev Board Manager -> Search for pico, it shows installed since my computer has already installed it.

Upload Demo At the First Time

  1. Press and hold the BOOTSET button on the Pico board, connect the Pico to the USB port of the computer via the Micro USB cable, and release the button when the computer recognizes a removable hard drive (RPI-RP2).

  2. Download the demo, open arduino\PWM\D1-LED path under the D1-LED.ino.
  3. Click Tools -> Port, remember the existing COM, do not need to click this COM (different computers show different COM, remember the existing COM on your computer).
