Arduino Support

A JetBrains CLion plugin to integrate Arduino CMake into the IDE.

JetBrains Plugin Page

Install and create Arduino CMake projects in one click with new project wizard types and view communications with the integrated serial monitor tool window.

• Arduino Sketch and Arduino Library project types to new project wizard, with Options to select board type, cpu, programmer and port.

• Arduino Sketch new file action.

• Serial port monitor tool window with options to disconnect on build start and reconnect on build complete.

• Change current build parameters Tools > Arduino Support > Change build settings.

• Customize template files used for creating new projects.

• Use bundled boards.txt and programmers.txt or your own versions.

:warning: Serial Port Monitor plugin may conflict with Arduino Support

This plugin uses Simple Serial Connector Service plugin, which uses jscc - Java Simple Serial Connector serial library, as does Serial Port Monitor plugin. Only one plugin can load the native libraries. If you encounter conflicts please uninstall or disable Serial Port Monitor plugin, or this plugin.

Uploading a sketch

Select the upload configuration from the dropdown. The type (debug/release) does not matter.

Use the build action to upload your sketch. Do not use the run action.

Settings (Preferences on Mac)

Some settings can also be changed in settings under Languages & Frameworks > Arduino, for convenience.

Additionally, you can point the plugin to your own versions of boards.txt and programmers.txt.

The Show Difference button is only displayed when a valid file is selected to let you quickly see if there are differences from the bundled version.

The Create From Bundled button is only displayed when a non-existent directory is given and it can be created. Pressing it will create the directory and populate it with the bundled templates. For layout and caveats of this directory please refer to the README.md file in that directory.

On Disconnect Delay, 50ms default. Introduces a short (0-100ms) delay before a build when disconnecting a port to allow the port to become available. On some projects with very short build times, disconnecting a port does not allow enough time for the port to become available, causing the upload to fail with "Resource busy" error. Adding a short delay after disconnect solves the problem. On some project it is not needed on others 20ms was sufficient.

Status

Updated to work with CLion 2020.3 to 2023.1, with fixes in the ArduinoToolchain.cmake.

Added an option not to use bundled toolchain file. This opens the possibility of using another toolchain.

Updated all native serial port code to jscc - Java Simple Serial Connector and moved code to Simple Serial Connector Service plugin to allow multiple plugins to provide serial port monitoring without conflicts on native libraries.

Wish List

• [x] Serial Terminal tool window
  • [ ] Add Hex pane in addition to text view. Either one or both could be displayed. With coordinated highlighting carets between the two. That way text view is not mangled into a block but naturally flows as you would expect, while hex view can be either a block or flow to match the text.
  • [ ] Display of ascii codes without resorting to hex display in text mode console.
• [ ] Refactoring support which CLion does not handle:
  • [ ] Add file to sources or headers (CLion cannot make sense of the Arduino project file)
  • [ ] Add updating of keywords.txt when identifiers in source or headers are renamed.
  • [ ] Add reload of CMakeLists.txt when library includes are added.
• [ ] Add Import Arduino IDE config, sketches and libraries
• [ ] Load Additional Libraries from URLs
• [ ] Add: Generate keywords.txt action to generate keywords.txt based on contained project classes and functions.
