35 .Nd GPIO control utility
67 utility could be used to manage GPIO pins from userland and list available pins.
71 argument can either be a
75 If it is a number and a pin has this number as its name and you did not use
83 The options are as follows:
84 .Bl -tag -width ".Fl f Ar ctldev"
85 .It Fl c Ar pin Ar flag Op flag ...
86 Configure pin by setting provided flags.
87 The following flags are currently defined:
88 .Bl -tag -offset indent -width ".Cm PULSE"
109 GPIO controller device to use
110 If not specified, defaults to
114 .It Fl n Ar pin Ar pin-name
115 set the name used to describe the pin
117 toggle value of provided pin
119 be verbose: for each listed pin print current configuration
123 to be interpreted as a pin number
127 to be interpreted as a pin name
132 List pins available on GPIO controller defined by device /dev/gpioc0
134 gpioctl -f /dev/gpioc0 -l
136 Set the value of pin 12 to 1
138 gpioctl -f /dev/gpioc0 12 1
140 Configure pin 12 to be input pin
142 gpioctl -f /dev/gpioc0 -c 12 IN
144 Set the name of pin 12 to test
146 gpioctl -f /dev/gpioc0 -n 12 test
148 Toggle the value the pin named test
150 gpioctl -f /dev/gpioc0 -t test
152 Toggle the value of pin number 12 even if another pin has the name 12
154 gpioctl -f /dev/gpioc0 -pt 12
