GPIO.CONF(5) File Formats Manual GPIO.CONF(5)
gpio.conf -- GPIO config file
The gpio.conf file is read by the gpio rc.d script during system start-up
and shutdown, and is intended for configuring GPIO pins.
Lines starting with a hash (`#') and empty lines are ignored. All other
lines are passed to gpioctl(8).
/etc/gpio.conf The gpio.conf configuration file resides in /etc.
/etc/rc.d/gpio rc.d(8) script that parses gpio.conf.
In this example, if the /etc/gpio.conf config file is present pin 1 of
/dev/gpio0 is set as output and named "error_led".
# Program pin 1 of /dev/gpio0 as output and name it "error_led"
gpio0 1 set out error_led
