Re: How can I change the username properly?

Can you not just use:
Code: Select all

s = GPIO.input(BUTTON1)

if s == False and m == False:
print 'Both pushed.'
sleep(1)

ls -al /dev/tty*
Plug the device in and run the command again, your device should be the one that's just appeared.

I've been using the new Rpi 7 inch touch screen as a control screen for a project. It's been really good so far.
