PlatformIO Daily Use Practice

(1) Start a new project
             $ platformio init --board uno --board nanoatmega328

If you need to add new board to the existing project please use platformio init again with all boards included.

(2) compile
Just compile:
             $platformio run

or

             $platformio run -e nanoatmega328

(3) flash/upload
             $platformio run -e nanoatmega328 -t upload
The awesome thing about this is that, even if using a CP2102 TTL to USB, it works perfectly.
