Detailed Description

Biometrics emulator test control functions.

Function Documentation

biometrics_emul_get_led_state()

enum biometric_led_state biometrics_emul_get_led_state

(

const struct device *

dev

)

#include <zephyr/drivers/biometrics/emul.h>

Get the current LED state.

Retrieves the current LED state that was set via biometric_led_control(). Used for verifying LED control commands.

Parameters

dev	Pointer to the biometrics device

Returns

Current LED state

biometrics_emul_set_capture_timeout()

void biometrics_emul_set_capture_timeout	(	const struct device *	dev,
		bool	timeout )

#include <zephyr/drivers/biometrics/emul.h>

Set whether capture operations should timeout.

Configures the emulator to simulate capture timeouts. When enabled, enrollment capture operations will return -ETIMEDOUT.

Parameters

dev	Pointer to the biometrics device
timeout	True to simulate timeout, false for normal operation

biometrics_emul_set_image_quality()

void biometrics_emul_set_image_quality	(	const struct device *	dev,
		int	quality )

#include <zephyr/drivers/biometrics/emul.h>

Set the image quality score.

Configures the image quality score that will be returned by capture and match operations. Used for testing quality feedback.

Parameters

dev	Pointer to the biometrics device
quality	Quality score (0-100)

biometrics_emul_set_match_fail()

void biometrics_emul_set_match_fail	(	const struct device *	dev,
		bool	fail )

#include <zephyr/drivers/biometrics/emul.h>

Set whether match operations should fail.

Configures the emulator to fail match operations with -ENOENT. Used for testing match failure scenarios.

Parameters

dev	Pointer to the biometrics device
fail	True to fail match operations, false for normal operation

biometrics_emul_set_match_id()

void biometrics_emul_set_match_id	(	const struct device *	dev,
		int	id )

#include <zephyr/drivers/biometrics/emul.h>

Set the template ID for identification matches.

Configures which template ID will be returned when performing an IDENTIFY match operation. Used for testing identification scenarios.

Parameters

dev	Pointer to the biometrics device
id	Template ID to return on successful match

biometrics_emul_set_match_score()

void biometrics_emul_set_match_score	(	const struct device *	dev,
		int	score )

#include <zephyr/drivers/biometrics/emul.h>

Set the match score for the biometrics emulator.

Configures the confidence/match score that will be returned by the next match operation. Used for testing match verification and identification.

Parameters

dev	Pointer to the biometrics device
score	Match score to return (sensor-specific scale)
