NAME

       gpioset - manual page for gpioset v1.6.3

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

       -B, --bias=[as-is|disable|pull-down|pull-up] (defaults to 'as-is'):

              set the line bias

       -D, --drive=[push-pull|open-drain|open-source] (defaults to 'push-pull'):

              set the line drive mode

       -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

   Biases:
       as-is: leave bias unchanged

       disable:
              disable bias

       pull-up:
              enable pull-up

       pull-down:
              enable pull-down

   Drives:
       push-pull:
              drive the line both high and low

       open-drain:
              drive the line low or go high impedance

       open-source:
              drive the line high or go high impedance

   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.
