35 .Nd GPIO control utility
58 utility could be used to manage GPIO pins from userland and list available pins.
60 The options are as follows:
61 .Bl -tag -width ".Fl f Ar ctldev"
62 .It Fl c Ar pin Ar flag Op flag ...
63 Configure pin by setting provided flags. The following flags are currently defined:
64 .Bl -tag -offset indent -width ".Cm PULSE"
85 GPIO controller device to use
86 If not specified, defaults to
91 toggle value of provided pin number
93 be verbose: for each listed pin print current configuration
98 List pins available on GPIO controller defined by device /dev/gpioc0
100 gpioctl -f /dev/gpioc0 -l
102 Set the value of pin 12 to 1
104 gpioctl -f /dev/gpioc0 12 1
106 Configure pin 12 to be input pin
108 gpioctl -f /dev/gpioc0 -c 12 IN
