Figure 30 User LEDs, push button and potentiometer in TRAVEO™ T2G Cluster 4M Lite kit
3.8.1 User LEDs
Since the LEDs used on the board are active high, the corresponding GPIO can be used to control the LED (high -
LED on and low - LED off) from the CYT3DL device.
3.8.2 User push button
The user push button used on the board is tied to a pull-up resistor and works as an active low input to the CYT3DL
device; therefore, pushing the button down triggers a falling edge on that particular GPIO port pin.
3.8.3 Potentiometer
The potentiometer works as a variable resistor connected on the analog pin of the CYT3DL device. Since the VDDA
power reference is given to the potentiometer, any change in its position has a relative effect on the ADC
conversion result.
