Arduino-CMake has the ability to connect the board through a serial terminal, just as you would with Arduino IDE.

To do that, you should pass the SERIAL parameter to the generate_arduino_firmware function.

The example below attempts to connect the board through the picocom serial interface:

generate_arduino_firmware(${CMAKE_PROJECT_NAME}
      SRCS  main.cpp
      PORT  /dev/ttyUSB0
      SERIAL picocom [SERIAL_PORT] -b 9600 -l
      BOARD uno)

Where [SERIAL_PORT] is the port used for serial connection.

The example above will create a target named ${CMAKE_PROJECT_NAME}-serial used specifically for connecting the program on the board through a serial terminal.

Each OS has its' own set of serial terminals, named differently. Below is the list of known serial terminals on each supported OS:

Linux has a variety of popular terminals that can be used. Below is a list of the most popular:

• minicom
• picocom
• gtkterm
• screen

In order to use one of them in Arduino-CMake, you should include the following line in your CMakeLists.txt:

set(${FIRMWARE_NAME}_SERIAL [TERMINAL] [SERIAL_PORT])

Where:

• [TERMINAL] is the name of the serial terminal used
• [SERIAL_PORT] is the terminal device (Such as /dev/tty.usbmodemXXX)

The easiest way to use a serial terminal in Mac is using the screen terminal emulator.

In order to use screen in Arduino-CMake, you should include the following line in your CMakeLists.txt:

set(${FIRMWARE_NAME}_SERIAL screen [SERIAL_PORT])

Where [SERIAL_PORT] is the terminal device (Such as /dev/tty.usbmodemXXX).

The most popular serial terminal for Windows systems which has multiple purposes and supports a handful of protocols is Putty.

In order to use putty in Arduino-CMake, you should add its' binary path to the System Path, then include the following line in your CMakeLists.txt:

set(${FIRMWARE_NAME}_SERIAL putty -serial [SERIAL_PORT])

Where [SERIAL_PORT] is the terminal device.
