Immediately after you will be asked if you want to make use of the Serial Port Hardware, make sure that you select Yes with your arrow keys and press Enter to proceed.ħ. You will now be prompted as to whether you want the login shell to be accessible over serial, select No with your arrow keys and press Enter to proceed.Ħ. With the next screen you will want to use the arrow keys again to select “ P6 Serial“, press Enter once highlighted to select this option.ĥ. Once this option has been selected, you can press Enter.Ĥ. Use the arrow keys to go down and select “ 5 Interfacing Options“. If you are after a more in-depth overview, you can check out our raspi-config tool guide. This tool allows us to make quite a numerous amount of different changes to the Raspberry Pi’s configuration, for now, though we are only after one particular option. This command will load up the Raspberry Pi configuration screen. This tool will allow us to easily disable the serial input/output interface that is enabled by default sudo raspi-configģ. Now that the Raspberry Pi is up to date we can make use of the raspi-config tool.

Let’s begin this tutorial by first ensuring the Raspberry Pi is up to date by running the following two commands. Setting up the Raspberry Pi for Serial Read and Writeġ. Make use of our table and guide below to connect your serial connector to your Raspberry Pi. Wiring your RS232 to TTL adapter to your Raspberry Pi is a simple process, with it requiring only 4 of the GPIO connecting to be wired to the serial connector, even better all 4 GPIO pins needed are in a row, so it is easy to follow. We mainly did this as we didn’t have any female to female breadboard wire available to us. You can connect the wires directly to the GPIO Pins or use the breadboard as a middleman as we did in this tutorial. On your RS232 to TTL adapter you should find at least four connections, some circuits do come with more connections, but the only four you need is: VCC (IC Power-supply pin), TX (Transmitted Data), RX (Received Data) and GND (Ground power-supply pin) Equipment Listīelow are all the bits and pieces that I used for this Raspberry Pi Serial Tutorial. If you’re interested, we have also go through the steps to handling Arduino’s serial reading and writing too, this in a separate tutorial.

We will also be teaching you how you would read and write data through the serial ports using the Python programming language, and this should give you a good idea how you would deal with standard serial devices and not just a loopback to the Raspberry Pi. You will be learning what GPIO pins you need to utilize to be able to wire up to your serial device to the Raspberry Pi, and we will also be showing the steps you must go through to allow the Raspberry Pi to read and write through the TX and RX GPIO pins.

We will be showing you how to do these serial writes by using an RS232 to TTL Adapter to create a loop back to the Raspberry Pi, and the same concept will work with any serial device.
