5.6.6.2
The ordering and numbering of sensors is related to the order in which the sensors are enabled.
This is independent of the acquisition method (QMatrix or QTouch acquisition method libraries).
For example, consider this code snippet:
….
In the case above, the slider on channels 0 to 2 will be sensor 0, the rotor on channels 3-to-5 is
sensor 1 and the keys on channels 6 and 7 are sensor numbers 3 and 4 respectively.
When the touch status is reported or queried, the corresponding sensor positions and status
indicate the touch status. For example, the slider is in detect if “qt_measure_data.
qt_touch_status.sensor_states” bit position 0 is set. Similarly, the rotor on channels 3 to 5 is
sensor 1, and the keys on channels 6 and 7 are sensors 2 and 3 respectively.
However, the code could be re-arranged as follows to give a different sensor numbering.
Now, the rotor is sensor 0, the keys are sensors 1 and 2, and the slider is sensor 3.
