Motors scan

Scan all ports to find the connected Dynamixel motors



In [2]:

    
import pypot.dynamixel

ports = pypot.dynamixel.get_available_ports()
if not ports:
    raise IOError('no port found!')
print 'ports found', ports









    



ports found ['/dev/ttyACM99']

Protocol is not the same for XL320 servomotors, set the using_XL320 flag to True if you use them. Set my_baudrate to the baudrate you are using (1000000 for motors already configured, 57600 for new ones).



In [3]:

    
using_XL320 = False
my_baudrate = 1000000

If the code below gives you an exception, try to restart all other notebooks that may be running, wait 5 seconds and try again.

for port in ports:
    print port
    try:
        if using_XL320:
            dxl_io = pypot.dynamixel.Dxl320IO(port, baudrate=my_baudrate)
        else:
            dxl_io = pypot.dynamixel.DxlIO(port, baudrate=my_baudrate)
        
        print "scanning"
        found =  dxl_io.scan(range(60))
        print found
        dxl_io.close()
    except Exception, e:
        print e

Kill whoever uses the ports (should be used only as last chance try to free the ports).
