===== Abstract =====


Here is the guide to show  that how to use python program control GPIOs .More others way to control can refer to http://docs.cubieboard.org/tutorials/common/gpio_on_lubuntu


===== Install python and lib =====
<code>
$sudo apt-get update
$sudo apt-get install python-dev
$wget http://dl.cubieboard.org/software/libs/pySUNXI-0.1.12.tar.gz
$tar zxf pySUNXI-0.1.12.tar.gz
$sudo python setup.py install

</code>


===== Connect the GPIO =====

Using the PD0 and VCC-5V for test.

==== Write a sample program ====
<code>
#!/usr/bin/env python

import SUNXI_GPIO as GPIO
import time

RED_LED = GPIO.PD0

GPIO.init()
GPIO.setcfg(RED_LED, GPIO.OUT)
    
while True:
        GPIO.output(RED_LED, GPIO.HIGH)
        time.sleep(1)
        GPIO.output(RED_LED, GPIO.LOW)
        time.sleep(1)
</code>


===== Run  program=====

<code>
$chmod +x blink.py
$sudo ./blink.py
</code>
The red led is blinking  in cycle time.
