Running a Python 3 script

[brightproject]

Hello @alduxvm, thanks for your work. This is not entirely an issue, perhaps someone has never encountered such a problem. I use WSL on Windows 10 to run Ubuntu.

py --version
Python 3.12.0

There I collect the firmware for betaflight from source code, and someone may use docker, but that’s not the point. So, I needed to get attitude angle data from the flight controller F411 NOXE V3 via the UART2. I got the code from here

https://github.com/alduxvm/pyMultiWii/blob/master/demo/show-attitude.py

But it didn’t want to work and gave an error. I had to change the code a little:

#except Exception,error:
except Exception as error:

After that, I could not determine the COM port, the command line always showed the message sendCMD... The solution to the problem was simple, because... I'm on Linux on WSL, then my ports are designated like this:

`COM1:` - `/dev/ttyS1`
`COM2:` - `/dev/ttyS2`
`COM3:` - `/dev/ttyS3`
...
`COM30:` - `/dev/ttyS30`

Information from here. As a result, the rewritten code for the COM15 port.

#!/usr/bin/env python

from pymultiwii import MultiWii

    #board = MultiWii("/dev/ttyUSB0")
    #board = MultiWii("/dev/tty.SLAB_USBtoUART")
    #board = MultiWii("COM15")
    board = MultiWii("/dev/ttyS15")
    try:
        while True:
            board.getData(MultiWii.ATTITUDE)
            #print (board.attitude) #uncomment for regular printing

            # Fancy printing (might not work on windows...)
            message = "angx = {:+.2f} \t angy = {:+.2f} \t heading = {:+.2f} \t elapsed = {:+.4f} \t".format(float(board.attitude['angx']),float(board.attitude['angy']),float(board.attitude['heading']),float(board.attitude['elapsed']))
            stdout.write("\r%s" % message )
            stdout.flush()
            # End of fancy printing
    #except Exception,error:
    except Exception as error:
        print ("Error on Main: "+str(error))

I receive orientation angle data.

python3 show-attitude.py
Waking up board on /dev/ttyS15...
1
angx = +2.90     angy = +21.70   heading = +57.00        elapsed = +0.0100

It works well!
