Function Documentation

calc_yaw()

float calc_yaw

(

struct ir_t *

ir

)

Calculate yaw given the IR data.

Parameters

ir	IR data structure.

calculate_basic_ir()

void calculate_basic_ir	(	struct wiimote_t *	wm,
		byte *	data
	)

Calculate the data from the IR spots.

Basic IR mode.

Parameters

wm	Pointer to a wiimote_t structure.
data	Data returned by the wiimote for the IR spots.

calculate_extended_ir()

void calculate_extended_ir	(	struct wiimote_t *	wm,
		byte *	data
	)

Calculate the data from the IR spots.

Extended IR mode.

Parameters

wm	Pointer to a wiimote_t structure.
data	Data returned by the wiimote for the IR spots.

wiiuse_set_aspect_ratio()

void wiiuse_set_aspect_ratio	(	struct wiimote_t *	wm,
		enum aspect_t	aspect
	)

Set the aspect ratio of the TV/monitor.

Parameters

wm	Pointer to a wiimote_t structure.
aspect	Either WIIUSE_ASPECT_16_9 or WIIUSE_ASPECT_4_3

wiiuse_set_ir()

void wiiuse_set_ir	(	struct wiimote_t *	wm,
		int	status
	)

Set if the wiimote should track IR targets.

Parameters

wm	Pointer to a wiimote_t structure.
status	1 to enable, 0 to disable.

wiiuse_set_ir_position()

void wiiuse_set_ir_position	(	struct wiimote_t *	wm,
		enum ir_position_t	pos
	)

Set the XY position for the IR cursor.

Parameters

wm	Pointer to a wiimote_t structure.

wiiuse_set_ir_sensitivity()

void wiiuse_set_ir_sensitivity	(	struct wiimote_t *	wm,
		int	level
	)

Set the IR sensitivity.

Parameters

wm	Pointer to a wiimote_t structure.
level	1-5, same as Wii system sensitivity setting.

If the level is < 1, then level will be set to 1. If the level is > 5, then level will be set to 5.

wiiuse_set_ir_vres()

void wiiuse_set_ir_vres	(	struct wiimote_t *	wm,
		unsigned int	x,
		unsigned int	y
	)

Set the virtual screen resolution for IR tracking.

Parameters

wm	Pointer to a wiimote_t structure.
status	1 to enable, 0 to disable.
