Help with Raspberry Pi,Pixl and XL-320 servo


I have a Pi 3B+ with Pypot installed. I bought a Pixl and connected the little board on the Pi. The Pixl is powered by a 7.4v battery. I only have 1 XL-320 servo plugged in.

I tried a test example of pypot that is supposed to connect to a dynamixel servo:

ports = pypot.dynamixel.get_available_ports()
print 'available ports:', ports

if not ports:
    raise IOError('No port available.')

port = ports[0]
print 'Using the first on the list', port

dxl_io = pypot.dynamixel.DxlIO(port)
print 'Connected!'

found_ids = dxl_io.scan()

It never gets out of the scan() function, or other calls to dxl_io for that matter…

What is happening? What did I do wrong?

(traduction en français disponible sur demande) :slight_smile:

you should use instead :

dxl_io = pypot.dynamixel.Dxl320IO(port)

Hello Thot,

Unfortunately, it still hangs as soon as I call scan()…


Is there a command to at least know that the Pixl is alive and kicking?

You shall try to do the same process as this :

I require the same clarification.I want to include that if any consequences faced regarding the gps signal error,accuracy,connectivity and any other issues consult with the most reliable garmin map updates free download 2019 for the ultimate solution.
