gpioset1

Usage

Overview

Set values of GPIO lines.

Lines are specified by name, or optionally by offset if the chip option is provided. Values may be '1' or '0', or equivalently 'active'/'inactive' or 'on'/'off'.

The line output state is maintained until the process exits, but after that is not guaranteed.

Options

--banner

display a banner on successful startup

-b, --bias <bias>

specify the line bias Possible values: 'pull-down', 'pull-up', 'disabled'. (default is to leave bias unchanged)

--by-name

treat lines as names even if they would parse as an offset

-c, --chip <chip>

restrict scope to a particular chip

-C, --consumer <name> consumer name applied to requested lines (default is 'gpioset')

-d, --drive <drive>

specify the line drive mode Possible values: 'push-pull', 'open-drain', 'open-source'. (default is 'push-pull')

-h, --help

display this help and exit

-l, --active-low

treat the line as active low

-p, --hold-period <period>

the minimum time period to hold lines at the requested values

-s, --strict

abort if requested line names are not unique

-t, --toggle <period>[,period]...

toggle the line(s) after the specified period(s) If the last period is 0 then gpioset exits else the sequence repeats.

--unquoted

don't quote line names

-v, --version

output version information and exit

-z, --daemonize

set values then detach from the controlling terminal

Note

It should not be assumed that a line will retain its state after gpioset exits. When a process exits, any GPIO lines it has requested are automatically released. Once released, the state of a line may be modified by the kernel or another process. To guarantee the requested value, by default gpioset does not exit.
