Reading data from serial in Python is very simple, but this is only the start.. Install PySerial with pip install pyserial
# Import the library import serial # Try to connect to the port try: fabkit = serial.Serial('/dev/tty.usbmodem1421', 9600) except: print "Failed to connect" exit() # Read data and print it to terminal... until you stop the program while 1: line = fabkit.readline() print line # We should close the connection... but since there's a while 1 loop before, we never reach this fabkit.close()
