.Dd November 7, 2013 .Dt GPIOCTL 1 .Os .Sh NAME .Nm gpioctl .Nd GPIO control utility .Sh SYNOPSIS .Nm .Cm -l .Op Fl f Ar ctldev .Op Fl v .Nm .Cm -t .Op Fl f Ar ctldev .Ar pin .Nm .Cm -c .Op Fl f Ar ctldev .Ar pin .Ar flag .Op flag ... .Nm .Op Cm -f Ar ctldev .Ar pin .Ar [0|1] .Sh DESCRIPTION The .Nm utility could be used to manage GPIO pins from userland and list available pins.
p The options are as follows: l -tag -width ".Fl f Ar ctldev" t Fl c Ar pin Ar flag Op flag ... Configure pin by setting provided flags. The following flags are currently defined: l -tag -offset indent -width ".Cm PULSE" t Cm IN Input pin t Cm OUT Output pin t Cm OD Open drain pin t Cm PP Push pull pin t Cm TS Tristate pin t Cm PU Pull-up pin t Cm PD Pull-down pin t Cm II Inverted input pin t Cm IO Inverted output pin .El t Fl f Ar ctldev GPIO controller device to use If not specified, defaults to
a /dev/gpioc0 t Fl l list available pins t Fl t Ar pin toggle value of provided pin number t Fl v be verbose: for each listed pin print current configuration .El .Sh EXAMPLES l -bullet t List pins available on GPIO controller defined by device /dev/gpioc0
p gpioctl -f /dev/gpioc0 -l t Set the value of pin 12 to 1
p gpioctl -f /dev/gpioc0 12 1 t Configure pin 12 to be input pin
