the signal comes from depends upon what type of feedback is needed. The most
basic type of feedback is called "momentary feedback". Momentary feedback causes
the button to display in its feedback state only when the button itself is pressed. This
type of feedback makes sense for functions that occur only while the button is
pressed. For example, volume up and down buttons typically receive momentary
feedback because the volume level only changes (goes up or down) while the
corresponding button is pressed. Momentary feedback can be achieved simply, by
connecting the button press signal name to the feedback signal for the same button
Programming Momentary Feedback
Certain buttons may call for more complex feedback. For example, a volume mute
button may alternately turn the mute on and off. To indicate this with feedback, the
button should display in the feedback state when the mute function is on, and turn off
when mute turns off. Clearly, momentary feedback will not do the trick here, so we
must use logic symbols to generate the desired behavior. This example shows how to
do this using the TOGGLE symbol.
