The Eclipse CDT (C/C++ Development Tooling) Project provides a fully functional C and C++ Integrated Development Environment based on the Eclipse platform. Features include: support for project creation and managed build for various toolchains, standard make build, source navigation, various source knowledge tools, such as type hierarchy, call graph, include browser, macro definition browser, code editor with syntax highlighting, folding and hyperlink navigation, source code refactoring and code generation, visual debugging tools, including memory, registers, and disassembly viewers.
Refer to the CDT Documentation page for more detailed information.
Integration process consists of these steps:
- Open system Terminal and install PlatformIO Core (CLI)
- Create new folder for your project and change directory (
cd) to it
- Generate a project using PIO Core Project Generator (
platformio project init --ide)
- Import project in IDE.
platformio project init --ide eclipse --board <ID> # For example, generate project for Arduino UNO platformio project init --ide eclipse --board uno
- Import this project via
Menu: File > Import... > General > Existing Projects into Workspace > Nextand specify root directory where is located “platformio.ini” (Project Configuration File)
- Open source file from
*.c, *.cpp, *.ino, etc.)
- Build project using
Menu: Project > Build Projector pre-configured Make Targets (see screenshot below):
PlatformIO: Build- Build project without auto-uploading
PlatformIO: Clean- Clean compiled objects.
PlatformIO: Test- PIO Unit Testing
PlatformIO: Upload- Build and upload (if no errors)
PlatformIO: Upload using Programmersee Upload using Programmer
PlatformIO: Upload SPIFFS imagesee Uploading files to file system SPIFFS
PlatformIO: Update platforms and libraries- Update installed platforms and libraries via platformio update
PlatformIO: Rebuild C/C++ Project Index- Rebuild C/C++ Index for the Project. Allows one to fix code completion and code linting issues.
If you have some problems with unresolved includes, defines, etc., then
- Rebuild PlatformIO Project Index:
PlatformIO: Rebuild C/C++ Project Indextarget
- Rebuild Eclipse Project Index:
Menu: Project > C/C++ Index > Rebuild
- Refresh Project, right click on the project
Project > Refresh(F5) or restart Eclipse IDE.
The libraries which are added, installed or used in the project
after generating process won’t be reflected in IDE. To fix it please run
PlatformIO: Rebuild C/C++ Project Index target and right click on the
Project > Refresh (F5).
C/C++ GCC Cross Compiler Support package must be installed
in Eclipse, otherwise the
CDT Cross GCC Built-in Compiler Settings
provider will not be available (check the
Providers tab in
Project > Properties > C/C++ General > Preprocessor Include Paths, Macros etc.
for a marked entry named
CDT Cross GCC Built-in Compiler Settings).
If this provider is not available, toolchain related includes cannot be resolved.
Eclipse Virtual IoT Meetup: PlatformIO: a cross-platform IoT solution to build them all!
A debugging feature is provided by PIO Unified Debugger and new debug configuration named “PlatformIO Debugger” is created. No need to do extra configuration steps!
- Build a project first time or after “Clean” operation using
- Launch debugger via “Menu: Debug” or “Bug Icon” button on Tool Bar.
- Wait for a while, PlatformIO will prepare project for debugging and session will be started soon.
