Description

Module for interfacing with serial ports. This module uses wjwwood/serial C++ library as its backend.

Constants

• flowcontrol_hardware — Flow control type (hardware) for the serial port
• flowcontrol_none — Flow control type (none) for the serial port
• flowcontrol_software — Flow control type (software) for the serial port
• parity_even — Parity type (even) for the serial port
• parity_mark — Parity type (mark) for the serial port
• parity_none — Parity type (none) for the serial port
• parity_odd — Parity type (odd) for the serial port
• parity_space — Parity type (space) for the serial port
• stopbits_one — Stop bits type (one) for the serial port
• stopbits_one_point_five — Stop bits type (one point five) for the serial port
• stopbits_two — Stop bits type (two) for the serial port

Functions

• list_ports() — Get the list of all available serial ports

Classes

• serial — This class provides a serial port interface
  
  

  Member Functions

  • construct() — The constructor. Create an instance of class serial and open the port
  • close() — Close the serial port
  • get_error() — Get the error string
  • is_open() — Get the open status of the serial port
  • read() — Read a given amount of bytes from the serial port and then return a string containing the data
  • readln() — Read from the serial port until eol_char is received
  • write() — Write a string to the serial port
• serial_port — This class stores serial port data from function list_ports()

Example

import serial
 
arduino = serial("/dev/ttyACM0")
 
if !arduino.is_open()
    exit(arduino.get_error())
endif
 
arduino.write("Hello")
 
data = arduino.readln()
writeln(data)
 
arduino.close()
