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
