Listen to events on GPIO lines, 0->1 1->0
-n <name> Listen on GPIOs on a named device (must be stated)
-o <n> Offset of line to monitor (may be repeated)
-d Set line as open drain
-s Set line as open source
-r Listen for rising edges
-f Listen for falling edges
-w Report the wall-clock time for events
-t Report the hardware timestamp for events
-b <n> Debounce the line with period n microseconds
[-c <n>] Do <n> loops (optional, infinite loop if not stated)
-? This helptext
Example:
gpio-event-mon -n gpiochip0 -o 4 -r -f -b 10000
