Here is the newbie again! I am learning how to use the BB UARTs. I am working on the example at https://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/uart
The minicom commands are not working for me.
- #first terminal window:
- minicom -b 9600 -D /dev/ttyO1
- #second terminal window:
- minicom -b 9600 -D /dev/ttyO2
I modified the program slighty thinking I could setup UART1 and UART2, cross the RX/TX of UART 1 and UART 2 as per the directions.
Since I can’t get the minicom to work for me is there another way I test everything is working?
Here is my program in Python:
import Adafruit_BBIO.UART as UART
#tty1 RX = P9_26 TX = P9_24
ser = serial.Serial(port = “/dev/tty1”, baudrate=9600)
#tty2 RX = P9_22 TX = P9_21
ser = serial.Serial(port = “/dev/tty2”, baudrate=9600)
print “Serial is open!”
print “Great Job”
Eventually, you’ll want to clean up, but leave this commented for now,
as it doesn’t work yet
I am expecting to be able to transmit and receive: “Hello Word!” right?
Thanks in advance,
