GPS Tracking: A GPS module can be connected to the Raspberry Pi via RS232 serial communication.There are many real-world applications of PySerial and RS232 communication on a Raspberry Pi. Finally, the close method is used to close the serial port.įor a more in-depth look at the pySerial library, visit. If there is data, it is decoded using the decode method and printed to the console. The if statement checks if there is any data received. The while loop continuously reads data from the serial port using the readline method until a newline character ' ' is received. The following line creates an instance of the Serial class and opens the serial port '/dev/ttyAMA0' with a baud rate of 9600. In this example, the first line imports the PySerial library.

Here's an example of how to receive data using PySerial: Finally, the close method is used to close the serial port. The write method sends the data 'Hello, World! ' over the serial port. The following line creates an instance of the Serial class and opens the serial port '/dev/ttyAMA0' with a baud rate 9600. Ser = serial.Serial('/dev/ttyAMA0', baudrate=9600) Here's an example of how to send data using PySerial: Sudo apt-get install python3-pip Sending Data: If you don't have pip3 installed, use the following command to install it: To do that, open the terminal on your Raspberry Pi and type the following command: To use PySerial, we need to install it first. This tutorial will teach us to use PySerial to send and receive data over RS232 serial communication on a Raspberry Pi. You can add RS232 to the Raspberry Pi using the Serial Pi Plus or Serial Pi Zero expansion boards from AB Electronics UK.įor information on enabling the UART port on your Raspberry Pi, view our tutorial Serial Port setup in Raspberry Pi OS. Raspberry Pi, a low-cost single-board computer, is commonly used for various applications, including communicating with serial devices such as GPS, modem, etc. RS232 is a standard for serial data transmission between computers and other devices. PySerial is a Python library used for working with serial ports.
