Function serial::construct()
Description
The constructor. Create an instance of class serial and open the port
serial::construct(port, timeout = 30000, baudrate = 9600, bytesize = 8, parity = parity_none, stopbits = stopbits_one, flowcontrol = flowcontrol_none)Parameters
port(string) — The address of the serial port. For example:"/dev/ttyS0"in Linux/macOS, and"COM1"in Windowstimeout(number, optional) — Timeout for the serial port (in milliseconds). The default value is 30000baudrate(number, optional) — Baud rate value. The default value is 9600bytesize(number, optional) — Size of each byte in the serial transmission of data. The default value is 8parity(number, optional) — Method of parity. The default value isparity_nonestopbits(number, optional) — Number of stop bits used. The default value isstopbits_oneflowcontrol(number, optional) — Type of flow control used. The default value isflowcontrol_none
Return Value
serial— Returns the instance of classserialand the handle to the opened port
Usage Example
import serial
arduino = serial("/dev/ttyACM0")
if arduino.is_open()
arduino.write("Hello")
arduino.close()
