Using GPIO in Orange Pi
http://www.instructables.com/id/Orange-Pi-One-Python-GPIO-basic/?ALLSTEPS
Here's how to get GPIO working in Python on the Orange Pi One.
Note. The GPIO pins on the Orange Pi One are flipped 180 degrees compared to the Orange Pi PC version or a Raspberry Pi!

Step 1: Download and Install Python Library
To start you will need the python headers and library installed, if you haven't or aren't sure just type:
https://github.com/duxingkei33/orangepi_PC_gpio_pyH3
extract the folder and place in '/home/pi'
from the terminal go into that directory:
sudo apt-get install python-devThen download the pyH3 library from:
https://github.com/duxingkei33/orangepi_PC_gpio_pyH3
extract the folder and place in '/home/pi'
from the terminal go into that directory:
cd orangepi_PC_gpio_pyH3then install it using:
python setup.py installThe library is now installed.
Step 2: Test It!
The way the pins are referred to are slightly different to a Raspberry Pi, they are named "ports" & "connectors".
UPDATE 03/05/2016: The new armbian images no longer export the gpios to /gpio_sw. See the above image for the port names. Image Credit: http://forum.armbian.com/index.php/topic/759-tutor...
For example pin 29 (BCM05) is port 'PA7'
To test, connect an LED to pin 29 through a 300ohm resistor then to the ground. (see diagram below)
and created a file called 'test.py':

and created a file called 'test.py':
#import the library from pyA20.gpio import gpio from pyA20.gpio import port from time import sleep #initialize the gpio module gpio.init() #setup the port (same as raspberry pi's gpio.setup() function) gpio.setcfg(port.PA7, gpio.OUTPUT) #now we do something (light up the LED) gpio.output(port.PA7, gpio.HIGH) #turn off the LED after 2 seconds sleep(2) gpio.output(port.PA7, gpio.LOW)Dont forget to make your test file executable:
chmod +x test.pyand run as root:
sudo su ./test.py
