uint8_t comms_match

(

void

)

Compares last sent values again current values of pertinent registersdetermine match based on key status registers, general status and slider position.

Returns

returns a NO_MATCH if registers don't match, MATCH if they do

void config_sensors ( void  )

static

Configure the sensors, assign the channel number, aks_group, hysteresis.

static void init_timer_isr ( void  )

static

configure timer ISR to fire regularly

static void qt_avr477_filter_cb ( void  )

static

This function is called every time the qt measuremement is done.

This is the pointer to callback function called before processing the signal

References tag_qt_touch_lib_measure_data_t::channel_signals, filter, qt_measure_data, and QT_NUM_CHANNELS.

static void qt_set_parameters ( void  )

static

This will fill the default threshold values in the configuration data structure.But User can change the values of these parameters .

This is used to initialize the configuration data for processing.
