pio init
> pio init The current working directory C:\Users\andreas\switchdrive\PlatformIO will be used for the project. The next files/directories have been created in C:\Users\andreas\switchdrive\PlatformIO include - Put project header files here lib - Put here project specific (private) libraries src - Put project source files here platformio.ini - Project Configuration File Project has been successfully initialized! Useful commands: `pio run` - process/build project from the current directory `pio run --target upload` or `pio run -t upload` - upload firmware to a target `pio run --target clean` - clean project (remove compiled files) `pio run --help` - additional information
