7
9 gpioset [OPTIONS] <line=value>...
10
12 Set values of GPIO lines.
13
14 Lines are specified by name, or optionally by offset if the chip option
15 is provided. Values may be '1' or '0', or equivalently 'active'/'inac‐
16 tive' or 'on'/'off'.
17
18 The line output state is maintained until the process exits, but after
19 that is not guaranteed.
20
22 --banner
23 display a banner on successful startup
24
25 -b, --bias <bias>
26 specify the line bias Possible values: 'pull-down', 'pull-up',
27 'disabled'. (default is to leave bias unchanged)
28
29 --by-name
30 treat lines as names even if they would parse as an offset
31
32 -c, --chip <chip>
33 restrict scope to a particular chip
34
35 -C, --consumer <name> consumer name applied to requested lines (default
36 is 'gpioset')
37
38 -d, --drive <drive>
39 specify the line drive mode Possible values: 'push-pull',
40 'open-drain', 'open-source'. (default is 'push-pull')
41
42 -h, --help
43 display this help and exit
44
45 -l, --active-low
46 treat the line as active low
47
48 -p, --hold-period <period>
49 the minimum time period to hold lines at the requested values
50
51 -s, --strict
52 abort if requested line names are not unique
53
54 -t, --toggle <period>[,period]...
55 toggle the line(s) after the specified period(s) If the last pe‐
56 riod is non-zero then the sequence repeats.
57
58 --unquoted
59 don't quote line names
60
61 -v, --version
62 output version information and exit
63
64 -z, --daemonize
65 set values then detach from the controlling terminal
66
67 Chips:
68 A GPIO chip may be identified by number, name, or path. e.g.
69 '0', 'gpiochip0', and '/dev/gpiochip0' all refer to the same
70 chip.
71
72 Periods:
73 Periods are taken as milliseconds unless units are specified.
74 e.g. 10us. Supported units are 's', 'ms', and 'us'.
75
77 The state of a GPIO line controlled over the character device
78 reverts to default when the last process referencing the file
79 descriptor representing the device file exits. This means that
80 it's wrong to run gpioset, have it exit and expect the line to
81 continue being driven high or low. It may happen if given pin is
82 floating but it must be interpreted as undefined behavior.
