Test CapSense Buttons with Toggle Feature Enabled
Touch any CapSense button; the respective LED turns on. When the finger is released from the but-
ton, the LED remains in the ON state. If the same button is pressed again, the LED turns off and
remains in same state when finger is released. At the next touch, the LED turns on and remains in
same state when finger is released. This means, every time the button is pressed, the state of the
button sensor output keeps toggling between the ON and OFF states. This behavior is seen on all
CapSense buttons.
