C/C++ Series

For C/C++, it is recommended to use Pico VS Code for development. This is a Microsoft Visual Studio Code extension designed to make it easier for you to create, develop, and debug projects for the Raspberry Pi Pico series development board. Whether you are a beginner or an experienced professional, this tool can help you confidently and easily develop Pico. Below we will introduce how to install and use the extension.

• Official website tutorial: https://www.raspberrypi.com/news/pico-vscode-extension/.
• This tutorial is applicable to Raspberry Pi Pico, Pico2, and our company's RP2040 and RP2350 series development boards.
• The development environment defaults to Windows as an example. For other environments, please refer to the official website tutorial for installation.

Arduino IDE Series

Install Arduino IDE

1. Download the Arduino IDE installation package from Arduino website.
   
   
2. Just click on "JUST DOWNLOAD".
   
   
3. Click to install after downloading.
   
   
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 "Additional boards manager URLs", then click OK.
   

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

   
   Note: If you already have the ESP32 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 -> Board -> 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 from #Resource, open the D1-LED.ino under arduino\PWM\D1-LED path.
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).
   
   
4. Connect the driver board to the computer with a USB cable, then click Tools -> Ports, select uf2 Board for the first connection, and after the upload is complete, connecting again will result in an additional COM port.
   
   
5. Click Tools -> Board -> Raspberry Pi Pico/RP2040 -> Raspberry Pi Pico.
   
   
6. After setting, click the right arrow to upload.
   
   
   • If you encounter problems during the period, you need to reinstall or replace the Arduino IDE version, uninstall the Arduino IDE clean, after uninstalling the software you need to manually delete all the contents of the folder C:\Users\[name]\AppData\Local\Arduino15 (you need to show the hidden files in order to see it) and then reinstall.
