•
This function can be called any time to apply the threshold parameters of the library as
specified by modifying the global data structure qt_config_data exported by the library.
A “Rotor” sensor requires contiguous channel numbers.

Comment
This function will initialize the parameters required by the library to default values .But
the default values can be changed by the user by modifying the global threshold
values as defined in qt_touch_lib_config_data_t . See section 0 for details.
