This API initializes the touch library Autonomous touch sensor. This API has to be called
before calling any other Autonomous touch API function.
Based on the input parameters, the CAT module is initialized with Autonomous Sensor
Pin and Register configuration.
The General configuration data provided by the p_general_config pointer is common to
both QMatrix, QTouch Group A, QTouch Group B and Autonomous Touch sensors.
touch_ret_t touch_at_sensor_enable( void)
This API enables the autonomous touch sensor and initiates continuous Touch
measurement on the Autonomous QTouch sensor.
When there is a change in the autonomous QTouch sensor status, the callback function
as specified in touch_at_status_change_interrupt_callback will be called. The callback
function lets the user know whether the autonomous QTouch sensor is currently in touch
or out of touch.
Note that this callback function will be called from an interrupt service routine. Hence it is
recommended to have as minimal code as possible in the callback function.
This API should be called only after touch_at_sensor_init API is called.
touch_ret_t touch_at_sensor_disable( void)
This API disables the Touch measurement on the Autonomous QTouch sensor. The
status change callback function is not called when the Sensor is disabled.
touch_ret_t touch_at_sensor_update_config( touch_at_param_t *p_at_param )
Type
touch_at_param_t*
configuration structure must be non-NULL.
