Choose board ID using platformio boards or Embedded Boards Explorer command and generate project via platformio init --ide command:

platformio init --ide codeblocks --board <ID>

# For example, generate project for Arduino UNO
platformio init --ide codeblocks --board uno


  1. Open this project via Menu: File > Open...
  2. Add new files to src directory (*.c, *.cpp, *.ino, etc.) via Menu: File > New > File...
  3. Build project using Menu: Build > Build
  4. Upload firmware using Menu: Build > Run


The libraries which are added, installed or used in the project after generating process wont be reflected in IDE. To fix it you need to reinitialize project using platformio init (repeat it).
