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:
gpio readall

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

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()
