GPIOCTL(1) BSD General Commands Manual GPIOCTL(1)NAME
gpioctl -- GPIO control utility
SYNOPSIS
gpioctl -l [-f ctldev] [-v]
gpioctl -t [-f ctldev] pin
gpioctl -c [-f ctldev] pin flag [flag ...]
gpioctl [-f ctldev] pin [0|1]
DESCRIPTION
The gpioctl utility could be used to manage GPIO pins from userland and list available pins.
The options are as follows:
-c pin flag [flag ...]
Configure pin by setting provided flags. The following flags are currently defined:
IN Input pin
OUT Output pin
OD Open drain pin
PP Push pull pin
TS Tristate pin
PU Pull-up pin
PD Pull-down pin
II Inverted input pin
IO Inverted output pin
-f ctldev GPIO controller device to use If not specified, defaults to /dev/gpioc0
-l list available pins
-t pin toggle value of provided pin number
-v be verbose: for each listed pin print current configuration
EXAMPLES
o List pins available on GPIO controller defined by device /dev/gpioc0
gpioctl -f /dev/gpioc0 -l
o Set the value of pin 12 to 1
gpioctl -f /dev/gpioc0 12 1
o Configure pin 12 to be input pin
gpioctl -f /dev/gpioc0 -c 12 IN
