CLion and Arduino via Platform.IO

Hi guys !

Here's my quick guide to set up CLion to work with the Arduino (and others) platforms. Once you get the gist (pun) of it, you should be fine !

Get Platform.IO

Follow the instructions here

Create a new project

# Create new folder YourProject
mkdir YourProject
platformio init -b uno -d YourProject

This will populate the folder YourProject with a src and lib folder.

Get the arduino libs

You should have somewhere on your drive the Arduino core library, on Windows I've found it in C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino. Copy its contents to the lib folder of your project along with the CMakeLists.txt file

Write your sourcecode

If you start having more than one file in your src folder, you'll need to add them to the src CMake file.

Read the Manual

CMake is a bit tricky to get at first, but it's a really powerful tool, and cross platform. With this setup you'll be able to develop on Windows and as well on Linux and OSX.

CLion

Open CLion and select "Import Project from Sources" and pick your newly created project. Once in the IDE, create a new Run configuration:

You will need to find the platformio executable and set it.

Enjoy !

}

Hey @adrien-f, thanks for sharing this! It's working pretty good for me except that CLion can't find the Arduino.h even though it's in the lib directory. I've also tried marking that directory as "library root" but that doesn't fix it either. Do you have any ideas?

This sample is not worked for me. I create my own, just clone this repo for check it out
https://github.com/whalemare/blink-clion

So, I was having problems with CLion not finding the Arduino.h and failing to build anything. What I needed to do was to launch CLion from the command line (to get the right PATH), and then go to settings->build, execution, deployment->cmake and make a new profile for the board name that I had. This let the exported cmakelists from pio find everything.
