5.6.5.4
In case of QMatrix acquisition method library, the from_channel and to_channel can be
between 3 to 8 channel numbers apart (i.e. it can support 3 to 8 channel rotors).
In case of QTouch acquisition method library, the from_channel and to_channel can be 3
channels apart (i.e. can support only 3 channel rotors).
qt_enable_slider
This function is used to configure a set of channels as a rotor.

5.6.5.5
A “Slider” sensor requires a contiguous numbers of channels.
The rotor / slider number depends on the order in which the rotor or sliders are enabled.
The first rotor or slider enabled will use “rotor_slider_values[0]”, the second will use.
“rotor_slider_values[1]”, and so on. The reported rotor value is valid when the slider is
reported as being in detect.
In case of QMatrix acquisition method library, the from_channel and to_channel can be
between 3 to 8 channels apart (i.e. it can support 3 to 8 channel sliders).
In case of QTouch acquisition method library, the from_channel and to_channel can be 3
channels apart (i.e. can support only 3 channel sliders).
qt_init_sensing
This function is used to initialize the touch sensing for all enabled channels. All required sensors
should be configured before calling this function.
