Ask for a refund from ncsu.edu you have been cheated Sent from Yahoo Mail on Android On Wed, May 18, 2016 at 4:46 PM, Shaurabh Kumar Singh<[email protected]> wrote: I have been trying to communicate with a CNC machine through RS 232 to the Beaglebone Black. Following are the Serial Port settings at the MachineBaudrate=9600Databits=8Stopbits=1Parity=NoneCR only When i tried connecting it to my desktop(windows 10-using python) directly(done without using BBB) and i set the same parameters i got the response from the machine like i had expected. Although, when done using the BBB (debian), also using python, i just received the string command i sent to the machine. Following is the python code. import Adafruit_BBIO.UART as UART import serial, string UART.setup("UART1")with serial.Serial(port="/dev/ttyO0",baudrate=9600,timeout=2) as ser: #i also tried mentioning databits and stopbits and other parameters but they still did not work ser.write(b"Q100\r") c=ser.readline().decode("utf-8","ignore") print(c) ser.close() This works all fine in windows(gives the serial no. as the output) but simply gives back Q100 as output (same as input). I was wondering if it could be due to the different OS on my laptop and BBB. Should i try installing windows ce on the BBB and work with that?
