How to setup PlatformIO & CH32 on Ubuntu 24.04.1

1. Setup

• Don't use sudo apt install platformio but if you did, try sudo apt remove platformio before proceeding further.

• Install python-venv :

  sudo apt-get install python3-venv
  

• Install PlatformIO :

  curl -fsSL -o get-platformio.py https://raw.githubusercontent.com/platformio/platformio-core-installer/master/get-platformio.py && python3 get-platformio.py
  

• It will be installed in /home/YOUR_USERNAME/.platformio/penv/bin/platformio, so you need to include it into your PATH or SYMLINK it like below to use pio CLI command from Terminal.

• Symlink into your ~/.local/bin :

  ln -s /home/YOUR_USERNAME/.platformio/penv/bin/platformio ~/.local/bin/pio
  

• Now try updating a library :

  pio pkg update -g -p "ch32v"    
  

** You now also may install PlatformIO plugin into your vscode.

• Install ch32v platform package :

  pio pkg install -g -p https://github.com/Community-PIO-CH32V/platform-ch32v.git
  

• Create udev-rule for ch32v usb access :

  sudo touch /etc/udev/rules.d/99-platformio-udev.rules
  

• Paste below lines into the rules :

  SUBSYSTEM=="usb", ATTR{idVendor}="1a86", ATTR{idProduct}=="8010", GROUP="plugdev"
  SUBSYSTEM=="usb", ATTR{idVendor}="4348", ATTR{idProduct}=="55e0", GROUP="plugdev"
  SUBSYSTEM=="usb", ATTR{idVendor}="1a86", ATTR{idProduct}=="8012", GROUP="plugdev"
  

That's it. Enjoy !
