Tutorial Gpio Setup/Teardown scripts

[Rich Neese]

Here is a easier way to do gpio setup/teardown

 

To setup ,

chmod +x armbian_gpio_up and gpio_down

 put the scripts armbian_gpio_up and armbian_gpio_down in /usr/sbin

put armbian_gpio.conf /etc

In the armbian_gpio.conf you just have to put the pin numbers 

as follows

 

# Space separated list of GPIO pins that point IN and have an
# Active HIGH state (3.3v = ON, 0v = OFF)
GPIO_IN_HIGH="10 12 27"

 

on the lines you need for high/low/in/out. 

Then run armbian_gpio_up to setup the gpio pins, 

and run armbian_gpio_down to teardown the gpio.

 

Then run armbian_gpio_up to setup the gpio pins, 

and run armbian_gpio_down to teardown the gpio.
