Code::Blocks is a free, open-source cross-platform IDE that supports multiple compilers including GCC, Clang and Visual C++. It is developed in C++ using wxWidgets as the GUI toolkit. Using a plugin architecture, its capabilities and features are defined by the provided plugins. Currently, Code::Blocks is oriented towards C, C++, and Fortran.

CodeBlocks IDE can be downloaded from here.



Integration process consists of these steps:

  1. Open system Terminal and install PlatformIO Core (CLI)

  2. Create new folder for your project and change directory (cd) to it

  3. Generate a project using PlatformIO Core Project Generator (pio project init --ide)

  4. Import project in IDE.

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

pio project init --ide codeblocks --board <ID>

# For example, generate project for Arduino UNO
pio project 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 won’t be reflected in IDE. To fix it you need to reinitialize project using pio project init (repeat it).
