4) Using QTouch API’s in your application to add touch functionality
5) Adding the necessary source files
The following files are to be added along with the touch library and user application
before compilation:
a. The clock, host application and other peripherals needed by the host application
b. In your application, create, initialize and configure the sensors.
c. The channel configuration parameters need to be set by calling the
d. Once the sensors are configured, qt_init_sensing() has to be called to trigger the
d. Provide timing for the QTouch libraries to operate. i,e the QTouch libraries do not
NOTE: The ATSAM example applications provided with the libraries illustrate the
usage for the evaluation kits supported by the library. Please refer to the main.c files
for reference.

provide the required timing and also call the API’s at the appropriate intervals to
perform touch sense detect operations.
