The configuration window will ask if you’d like the login shell to be accessible over serial. In Raspberry Pi, open the Terminal window (Bash shell) and execute this command:Ģ. In this tutorial, we’ll learn how to use the Python Serial library to setup bidirectional communication with a computer.Īs discussed in the serial communication on Raspberry Pi tutorial, the default serial Linux console on Raspberry Pi OS must be disabled to use RPi’s serial TTL port for UART communication.įollow these steps to disable RPi’s serial Linux console:ġ. We also learned how to find a serial port name on Linux, Windows, macOS, and Raspberry Pi (RPi). In the previous tutorial, we discussed the universal asynchronous receiver-transmitter (UART) protocol and voltage levels, covering USB-serial boards and other serial adaptors.
