Adafruit GPIO input shows large negative number

Hi Folks,

I have a BBB with Ubuntu 14.04. I’m using the Adafruit python GPIO library. When I read a GPIO input, instead of getting a 1 or 0, I’m getting a large negative value like -1227579032.

My code is simple. At the Python prompt.

import Adafruit_BBIO.GPIO as GPIO
GPIO.setup_“P9_13”, GPIO.IN)
GPIO.input(“P9_13”)
-1227579032

The number is the same no matter which IO is use as input.
The result is independent of having the IO float or grounded.

Ideas?

Thanks,
Paul
