This library can be used in various projects ranging from robotics, IoT, and embedded systems. Overall, python serial library provides a convenient and efficient way to establish serial communication with various devices and exchange data. We then send a message 'Hello, World!' and read the response. We are also setting the DTR and RTS pins to False to configure the device for sending data. In this example, we are configuring some of the serial communication parameters like baud rate, data bits, parity, stop bits, and timeout. Ser = serial.Serial('/dev/ttyUSB0', baudrate=115200, bytesize=8, The response is then printed on the console.Įxample 2: Configuring the serial communication parameters We are then sending a message 'Hello, World!' to the device and reading the response. In this example, we are creating a serial object with the port '/dev/ttyUSB0' and baud rate 9600. Response = ser.readline() # read response Ser.write(b'Hello, World!\n') # send data Ser = serial.Serial('/dev/ttyUSB0', 9600) # create serial object Here are some code examples using python serial library:Įxample 1: Sending and receiving data through serial communication The library provides a simple and easy-to-use interface for establishing serial communication and also provides various options for configuring the communication parameters like baud rate, parity, stop bits, etc. Python serial library is used for establishing serial communication between the computer and various external devices like microcontrollers, GPS modules, sensors, etc.
