OrangePi Zero Pinout

Using GPIO w/ Orange PI

GPIO can be modified from the command line using WiringOP:

git clone https://github.com/zhaolei/WiringOP.git -b h3 
cd WiringOP
chmod +x ./build
sudo ./build

Documentation can be found in the man pages or here: http://wiringpi.com/the-gpio-utility/. Test the tool using:

Use the table to determine the correct pin. The wPi column is the ID for the pin. For output, use the following command to change the corresponding pin's mode gpio mode <pin> in/out/pwm/clock/up/down/tri:

gpio mode 2 out

Once the mode is set correctly, use:

gpio write 0 1

To turn the flag off, and then:

gpio write 0 0 

Python

Follow the instructions at https://opi-gpio.readthedocs.io/en/latest/

Install PIP

sudo apt-get install python-pip

Install the GPIO library:

 sudo pip install --upgrade OPi.GPIO

A simple python script to turn the flag off or on:

import OPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BOARD)
GPIO.setup(11, GPIO.OUT)

# turn it off
GPIO.output(11,GPIO.HIGH)

# turn pin 11 on and wait 5 seconds
GPIO.output(11,GPIO.LOW)
time.sleep(5)

#turn it back off
GPIO.output(11,GPIO.HIGH)
GPIO.cleanup()
