UART — UART communications interface

UART functionality of a BeagleBone using Python. Generally used to set up and grant access to a given UART device, which will then be accessed by other software or modules (e.g. pyserial):

sudo pip install pyserial

Example:

import Adafruit_BBIO.UART as UART
import serial

UART.setup("UART1")

ser = serial.Serial(port = "/dev/ttyO1", baudrate=9600)
ser.close()
ser.open()
if ser.isOpen():
     print "Serial is open!"
     ser.write("Hello World!")
ser.close()

Adafruit_BBIO.UART.setup_uart(channel)

Set up and start the UART channel. This function will effectively export the given UART so that it can be accessed by other software that controls its serial lines.

Parameters:channel (str) – UART channel to set up. One of “UART1”, “UART2”, “UART4” or “UART5”

Adafruit_BBIO.UART.cleanup()

Cleans up the UART.
