NAME

gpioget - libgpiod command-line utility

SYNOPSIS

gpioget [ OPTIONS ] <line> ...

DESCRIPTION

Read values of GPIO lines.

Lines are specified by name, or optionally by offset if the chip option is provided.

OPTIONS

-a , --as-is

leave the line direction unchanged, not forced to input

-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 ’gpioget’)

-h , --help

display this help and exit

-l , --active-low

treat the line as active low

-p , --hold-period <period>

wait between requesting the lines and reading the values

--numeric

display line values as ’0’ (inactive) or ’1’ (active)

-s , --strict

abort if requested line names are not unique

--unquoted

don’t quote line names

-v , --version

output version information and exit

Chips:

A GPIO chip may be identified by number, name, or path. e.g. ’0’, ’gpiochip0’, and ’/dev/gpiochip0’ all refer to the same chip.

Periods:

Periods are taken as milliseconds unless units are specified. e.g. 10us. Supported units are ’m’, ’s’, ’ms’, and ’us’ for minutes, seconds, milliseconds and microseconds respectively.
