Type Constant Return Value Integer Description The name of a keypad property that causes the buzzer to sound when a key is pressed. The KEYPAD_BEEP property for all keypads is set to GUI_TRUE by Initialize_GUI. Usage Set_Property(GUI_KEYPAD0, KEYPAD_BEEP, GUI_TRUE);
Library library.c
KEYPAD_BEEP_DURATION
Type Constant Return Value Integer Description The name of a keypad property that sets the length of the beep when a key is pressed. The units for the KEYPAD_BEEP_DURATION property is in timeslice counts or 5 millisecond intervals. The KEYPAD_BEEP_DURATION property is different from the BEEP_TIME property of the GUI_BUZZER object. This allows you to set different beep times for each keypad and use the GUI_BUZZER for alarms or notifications.
