sensor_attribute_grow_r502a

enum sensor_attribute_grow_r502a

Enumerator
SENSOR_ATTR_R502A_CAPTURE	To capture finger and store as feature file in RAM buffers char_buf_1 and char_buf_2.
SENSOR_ATTR_R502A_TEMPLATE_CREATE	create template from feature files at RAM buffers char_buf_1 & char_buf_2 and store a template data back in both RAM buffers char_buf_1 and char_buf_2.
SENSOR_ATTR_R502A_RECORD_ADD	Add template to the sensor record storage. Parameters val->val1 record index for template to be stored in the sensor device's flash library.
SENSOR_ATTR_R502A_RECORD_FIND	To find requested data in record storage. Returns val->val1 matched record index. val->val2 matching score.
SENSOR_ATTR_R502A_RECORD_DEL	To delete mentioned data from record storage. Parameters val->val1 record start index to be deleted. val->val2 number of records to be deleted.
SENSOR_ATTR_R502A_RECORD_FREE_IDX	To get available position to store data on record storage.
SENSOR_ATTR_R502A_RECORD_EMPTY	To empty the storage record.
SENSOR_ATTR_R502A_RECORD_LOAD	To load template from storage to RAM buffer of sensor. Parameters val->val1 record start index to be loaded in device internal RAM buffer.
SENSOR_ATTR_R502A_COMPARE	To template data stored in sensor's RAM buffer. Returns val->val1 match result. [R502A_FINGER_MATCH_FOUND or R502A_FINGER_MATCH_NOT_FOUND] val->val2 matching score.
SENSOR_ATTR_R502A_SYS_PARAM	To read and write device's system parameters. sensor_attr_set Parameters val->val1 parameter number from enum r502a_sys_param_set. val->val2 content to be written for the respective parameter. sensor_attr_get Returns val->ex.data buffer holds the system parameter values.
