1. In the file platformio.ini use: monitorspeed instead of monitorbaud. Monitorbaud option is deprecated and will be removed in the next release! Please use monitorspeed instead. For example: monitorspeed = 115200 👍.
2. Probably just what the command is called. Platformio device monitor. And for bonus points, there’s also platformio device list, which, well, lists devices!

Arduino IDE times

此时，打开Terminal，输入platformio device monitor，就可以打开串口监视器，查看串口输出． 串口监视器的比特率默认是9600．如果你想换一下的话，比如115200，除了把代码中的Serial．begin（9600）换成Serial．begin（115200）以外，还需要在platformio．ini中加一句monitorspeed.

Recently i've started to play with Arduino and also different other micro controllers like esp8266.
Originally i've used Arduino IDE to develop and upload sketches to the MCU.
But as a java/javascript software developer i always felt myself unhappy since i could not use my favourite IntelliJ IDEA for this. There is a CLion Arduino plugin present in IntelliJ plugins repository i've tried it but still was unhappy (also i used trial version of CLion since it does not have community version).
But recently i've found such a great project - PlatformIO created by Ivan Kravets from Ukraine which is very great since i'm also from Ukraine.

PlatformIO to the rescue

In short PlatformIO is free and open-source cross-platform code builder and library manager for Arduino with Continuos and IDE integration. It has pre-configured settings for the most Arduino Boards.
The great thing is that it supports not only Arduino but other MCU's as well - you could see list of supported platforms here. Also it does not require installed Arduino IDE - it is completely independent solution: toolchain for specific platform is downloaded and managed by Platformio.
So how to use PlatformIO and how to integrate it with IntelliJ IDEA?

using PlatformIO within IntelliJ IDEA

Installing PlatformIO

after this lets install PlatformIO by itself:

Creating new project with PlatformIO

Now lets create first project with platformio. Create folder where your test project will be placed, cd to this folder. Then run:
Here i've created project for the Adruino UNO board. If you wish to use other board - you could find it's name using the following command:
And then just find in the command output name of your board (for Arduino boards see atmelavr platforms section). An example output of this command is the following:
Name from type column is what you need to specify in --board parameter.
After initialising your project structure will be the following:
.gitignore - handy if you going to store your project in git cvs.
.travis.yml - for CI integration
lib - place here your libraries
platformio.ini - main configutation file. For now its ok to use defaults here.
src - your sketch should be placed here.

Compiling and uploading sample blink sketch with PlarformIO

lets create sample blink sketch:

• create file blink.ino in src folder
• copy blink example into this file:
  

now we can compile the code by running the following command in the root folder of our sample blink project:
The sample output looks like:
Great! Compilation was sucessful!
Lets upload this sketch to the Arduino UNO board. Attach arduino board to your mac or pc and run the following command:
platformio will try to recognize usb port to which arduino is attached and will upload your sketch to the board.
Thats it!

IntelliJ IDEA (and CLion as well as other IntelliJ products) integration

So starting from now you do not need Arduino IDE - you could compile and upload your sketches directly via command line!
But wait... what about IntelliJ IDEA integration?
Well integration of PlatformIO with IDEA is far from excellent - unfortunately there is no IDEA plugin for PlatfomIO yet, so let's see what we could do.

Creating IDEA project from PlatformIO project

Now you could see our project opened:

Using Ant build file for IDEA build config support

After this we could add these ant targets to build config.
First open Ant plugin toolbar:

Or you could create new build config.
To do this click 'Edit Configurations...' in the main toolbar:

Click + sign to add new configuration and choose 'Ant Target':


Click on a ... button right below build config name - you will see all available ant targets. Choose one you want to execute, for example 'upload':
Then click 'Ok':

That's it!

Clion Platformio Serial Monitor Power Cord

Not so much integration as you would probably expect, but for me it's much more better than using native Arduino IDE.

Thanks a lot for reading this long post to the end!

Clion Platformio Serial Monitor Calibration

See you later!

The current arduino development workflow in CLion with serial monitor looks like:

1. Make code changes
2. Upload firmware
3. Connect serial monitor
4. Test stuff you wrote
5. Disconnect serial monitor.
6. Go to 1

The 3rd and 6th items are very annoying but necessary because serial monitor and firmware upload tool (avrdude) cannot use the port simultaneously (can they?). It would be good if those steps could be done automatically. However I'm not sure if it's can be done solely in serial monitor, probably it requires cooperation between serial monitor, CLion and platformio developers.
