The gpioctl
utility could be used to manage GPIO pins
from userland and list available pins.
The pin argument can either be a
pin-number or a pin-name. If
it is a number and a pin has this number as its name and you did not use
-N
or -p
, then
gpioctl
exits.
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
-n
pin pin-name
- set the name used to describe the pin
-t
pin
- toggle value of provided pin
-v
- be verbose: for each listed pin print current configuration
-p
- Force pin to be interpreted as a pin number
-N
- Force pin to be interpreted as a pin name
- List pins available on GPIO controller defined by device /dev/gpioc0
gpioctl -f /dev/gpioc0 -l
- Set the value of pin 12 to 1
gpioctl -f /dev/gpioc0 12 1
- Configure pin 12 to be input pin
gpioctl -f /dev/gpioc0 -c 12 IN
- Set the name of pin 12 to test
gpioctl -f /dev/gpioc0 -n 12 test
- Toggle the value the pin named test
gpioctl -f /dev/gpioc0 -t test
- Toggle the value of pin number 12 even if another pin has the name 12
gpioctl -f /dev/gpioc0 -pt 12
The gpioctl
utility appeared in FreeBSD
9.0.
