Atmel QTouch Library User Guide

• This API updates the configuration of a QTouch sensor with values different from theones initialized by the touch_qt_sensor_config API. If the sensor was not configuredalready, the API will return error.• The user must populate the structure pointed by p_touch_sensor_param with requiredsettings before calling this API.touch_qt_sensor_get_configtouch_ret_t touch_qt_sensor_get_config(touch_qt_grp_t touch_qt_grp,sensor_id_t sensor_id,touch_qt_param_t *p_touch_sensor_param)Arguments Type Commenttouch_qt_grp touch_qt_grp_t Specify if the operation is to beperformed on Group A Sensors orGroup B Sensors.sensor_id sensor_id_t Sensor ID for which the configurationneeds to be updated.p_touch_sensor_param touch_qt_param_t* Pointer to the user sensor configurationstructure.• This API copies the current configuration of a QTouch sensor into the user configurationstructure.touch_qt_update_global_paramtouch_ret_t touch_qt_update_global_param(touch_qt_grp_t touch_qt_grp,touch_global_param_t *p_global_param )Arguments Type Commenttouch_qt_grp touch_qt_grp_t Specify if the operation is to be performed on Group ASensors or Group B Sensors.p_global_param touch_global_param_t Pointer to user global parameters structure forQTouch Group A/B.• This API can be used to update the QTouch A or QTouch B global parameters, withvalues different from the ones initialized using touch_qt_sensors_init API.touch_qt_get_global_paramtouch_ret_t touch_qt_get_global_param(touch_qt_grp_t touch_qt_grp,touch_global_param_t *p_global_param )Arguments Type Commenttouch_qt_grp touch_qt_grp_t Specify if the operation is to be performed on Group ASensors or Group B Sensors.p_global_param touch_global_param_t Pointer to user global parameters structure forQTouch Group A/B.• This API can be called to retrieve the QTouch Group A or Group B global parameters.161
