Fields
sensor_states[]
rotor_slider_values[]
The macro that can get the sensor state when the sensor number is provided can be something
as below:
#define
(1 << (SENSOR_NUMBER % 8))
The host application can use this macro to act accordingly, the following example shows how to
toggle a IO pin (PD2) based on the sensor0 state.( Set PD2 if sensor0 is in detect, and clear PD2
if sensor0 is not in detect)
Ex:

Data structures
qt_measure_data.qt_touch_status.sensor_states[(SENSOR_NUMBER/8)] &
/*Set pin PD2 direction as output*/
DDRD |= (1u << PORTD2);
if (GET_SENSOR_STATE(0) !=0)
{
}
else {
}

GET_SENSOR_STATE(SENSOR_NUMBER)
PORTD |= (1u << PORTD2); /* Set PORTD2 */
PORTD &= ~(1u << PORTD2); /* Clear PORTD2 */
qt_touch_status_t
Output from the Library
Holds the status ( On/ Off ) of the sensors and the linear and angular positions
of sliders and rotors respectively
For Sensor, the sensor_states. Bit “n” = state of nth sensor :
Bit Value 0 - indicates the sensor is not in detect
Bit Value 1 - indicates the sensor is in detect
values are valid when sensor states shows that the corresponding rotor or
slider is in detect
Comment
Rotors angles or slider positions if rotors and sliders are used. These
