Demo project CLion + Arduino Mega2560 + AVR-GCC compiler

Demo project CLion + Arduino Uno + AVR-GCC compiler

Note Debug is not supported yet

Prerequirements

Hardware

• Arduino Uno or compatible board

All platforms(MAC, Linux, Windows)

• CLion 2020.1+
• AVR8 GNU Toolchain
• avrdude

Windows only

• MinGW
• Virtual COM port driver for Arduino

HOWTO

Use the project

• Open the project with CLion
• Setup a new CLion Toolchain (i.e. set compilators and debugger location) with your AVR8 GNU installation (Settings -> Build, Execution, Deployment -> Toolchains). You may use either avr-gdb-py or avr-gdb. First one is better but requires Python to be installed.

Screenshot 1

• Use the toolchain for the project (Settings -> Build, Execution, Deployment -> CMake -> Toolchain:)

Screenshot 2

• Adjust CMakeLists.txt settings, such as avrdude location and actual COM port
• Select FLASH run configuration
• Build it. Arduino yellow LED should start blinking about 1Hz

Use simulator(simavr)

• Install the simulator
  • Linux, Mac, see https://github.com/buserror/simavr
  • Windows install (https://sourceforge.net/projects/simutron/files/), simavr comes with it
• Open the project with CLion
• Setup AVR toolchain and CMake as above
• Open SIMAVR Run Configuaration and set actual path to simavr executable

Screenshot 3

• Set a breakpoint somewhere in your main()
• Select SIMAVR Run Configuaration
• Click Debug
• Enjoj!

Diagnose problems

• Uncomment avrdude verbose switch

Use another AVR-based board

• Check if this repository contains a branch dedicated to your CPU
• Clone this project
• Make adjustments as in "Use the project"
• Open the project with CLion
• Correct CMakeLists.txt
  • Project name in add_executable() clause
  • List of source files in add_executable clause
  • add include_directories() clause(s) if needed
  • TARGET_CPU
  • FLASH custom target command line to reflect another hardware
