NAME

       gpioset - manual page for gpioset (libgpiod) v1.4.1

SYNOPSIS

       gpioset [OPTIONS] <chip name/number> <offset1>=<value1> <offset2>=<value2> ...

DESCRIPTION

       Set GPIO line values of a GPIO chip and maintain the state until the process exits

OPTIONS

       -h, --help:
              display this message and exit

       -v, --version:
              display the version and exit

       -l, --active-low:
              set the line active state to low

       -m, --mode=[exit|wait|time|signal] (defaults to 'exit'):

              tell the program what to do after setting values

       -s, --sec=SEC:
              specify the number of seconds to wait (only valid for --mode=time)

       -u, --usec=USEC:
              specify the number of microseconds to wait (only valid for --mode=time)

       -b, --background:
              after setting values: detach from the controlling terminal

   Modes:
       exit:  set values and exit immediately

       wait:  set values and wait for user to press ENTER

       time:  set values and sleep for a specified amount of time

       signal:
              set values and wait for SIGINT or SIGTERM

       Note:  the  state  of  a GPIO line controlled over the character device reverts to default
       when the last process referencing the file descriptor representing the device file  exits.
       This  means  that  it's wrong to run gpioset, have it exit and expect the line to continue
       being driven high or low. It  may  happen  if  given  pin  is  floating  but  it  must  be
       interpreted as undefined behavior.
