Hello:)
I have a new problem. I use now a script to read the data from the external
device (see my post
before:
http://beagleboard.org/Community/Forums?place=msg%2Fbeagleboard%2FpfRLpoOEv9M%2Fj4LJHPGOJgAJ
). This script is just a copy of the script in the linked tutorial. I just
changed the
Thank you very much for the input. Now it works:)
I switched the wires and i played around with the tutorial.
I use now this script:
import serial, fcntl, struct, time
ser = serial.Serial(
port='/dev/ttyO4',
baudrate=9600,
timeout=10,
parity=serial.PARITY_EVEN,
stopbits=seri
The BeagleBone's omap-serial driver doesn't support RS-485 DE/RE control
with the RTS flow control signal. Instead it has an RS-485 mode using a
GPIO pin for DE/RE control, and has a modified serial_rs485 struct from the
standard serial driver. You have to use ioctl on the corresponding
/dev/tt
