gpioset - manual page for gpioset (libgpiod) v1.3


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


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


display this message and exit
display the version and exit
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
specify the number of seconds to wait (only valid for --mode=time)
specify the number of microseconds to wait (only valid for --mode=time)
after setting values: detach from the controlling terminal


set values and exit immediately
set values and wait for user to press ENTER
set values and sleep for a specified amount of time
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.
