NOTE: I haven't actually run this with anything connected to the GPIO...

debian@beaglebone:~$ cat gpio_test.py
#!/usr/bin/env python3
import Adafruit_BBIO.GPIO as GPIO
import time
PIN = "P9_30"
GPIO.setup(PIN, GPIO.OUT)
GPIO.output(PIN, GPIO.LOW)
for t in range(10):
print("on %s" % t)
GPIO.output(PIN, GPIO.HIGH)
time.sleep(t)
print("off %s" % (10 - t))
GPIO.output(PIN, GPIO.LOW)
time.sleep(10 - t)
GPIO.cleanup()
debian@beaglebone:~$

That should toggle the GPIO in a 10 second cycle, starting with a short
on, long off, and ending with a long on, short off... 100 seconds total.
debian@beaglebone:~$ python3 gpio_test.py
