[IAEP] Arduino and XO-1

[Alan Jhonn Aguiar Schwyn]

If he have the latest version, the plugin makes a list of the ttyUSB availables andtry get the first that works.
The header of the Arduino Plugin says:
        self._dev = '/dev/ttyUSB0'        self._baud = 57600        self._arduino = None
        status,output = commands.getstatusoutput("ls /dev/ | grep ttyUSB")        output = output.split('\n')        for i in output:	        status,aux=commands.getstatusoutput("udevinfo -a -p /class/tty/%s | grep ftdi_sio > /dev/null" % i)	        if (not status):		        self._dev='/dev/%s' % i		        break
I'm not sure if the "udevinfo" commands exist in the XO.In my Ubuntu 12.10 I not have it, only the "udevadm"
Which sugar version you have?
In the Terminal Activity:
check for the N of the arduino:
ls /dev/ | grep ttyUSB
After, check if exist the udevinfo:
See the n, and replace the * in this line:
udevinfo -a -p /class/ttyUSB* | grep ftdi_sio

Tony,
Thanks.  I'll check it out.

Maybe the baud rate or the device name do not match.



Somewhere in the Arduino plugin code it searches for ttyusbn where n=1,2,3 ...



Your Arduino board could be ttyusbn or ttyacmn where n increments each time you replug the Arduino. Somewhere, I think /dev , you can see what your Arduino is.



Somewhere in the Firmata listing the baud rate is set, check its the same in the plugin code.
