Crash course on PlatformIO

PlatformIO is a Python based command line interface to compile and upload code to an Arduino microcontroller.

Install platformio

pip install platformio

Initialize a Platformio project and specify compilation for Arduino Uno

# initialize platformio in the current directory
platformio init --board uno # arduino uno

#additional boards can be added
platformio init --board teensy31 # arduino teensy31

Put a C++ .cpp file into platformio /src/ folder

Put .cpp Arduino source code into the /src/ directory

Tweek platformio.ini

platform = atmelavr
framework = arduino
board = uno
build_flags = -D _expose_interrupts_ #creates compiler directive

platform = teensy
framework = arduino
board = teensy31

Compile and upload code

platformio run #compile arduino code
platformio run --target upload #compile and upload
platformio run --target clean #clean project

Open a serial port with platformio

#this assumes the Arduino code is listening to serial at baud 115200
platformio serialports monitor -p /dev/ttyACM0 -b 115200 #a serial port monitor

Find the correct serial port by listing /dev/tty*

ls /dev/tty*

Specify the correct serial port

/dev/ttyACM0 #uno
/dev/ttyACM0 #teensy on raspberry
/dev/tty.usbmodem618661 #teensy on osx
/dev/ttyUSB0 #hand soldered arduino micro (home debian)
/dev/tty.usbserial-A50285BI # hand soldered arduino micro on osx
