# Demo project CLion + Arduino Uno + AVR-GCC compiler

**Note** Debug is not supported yet

## Prerequirements

### Hardware

- [Arduino Uno or compatible board](https://store.arduino.cc/usa/arduino-uno-rev3)

### All platforms(MAC, Linux, Windows)

- [CLion 2020.1+](https://jetbrains.com/clion)

- [AVR8 GNU Toolchain](https://www.microchip.com/mplab/avr-support/avr-and-arm-toolchains-c-compilers)

- [avrdude](https://download.savannah.gnu.org/releases/avrdude/)

### Windows only

- [MinGW](https://sourceforge.net/projects/mingw-w64/)

- [Virtual COM port driver for Arduino](https://www.arduino.cc/en/Guide/DriverInstallation)

 

## 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.

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

![CLion Settings Part II](docs/settings_cmake.png "CLion Settings Part II")

 

- 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

![CLion Run Configuration](docs/run_config.png "CLion Run Configuration")

 

- 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
