Function Documentation

void calc_joystick_state	(	struct joystick_t *	js,
		float	x,
		float	y
	)

Calculate the angle and magnitude of a joystick.

Parameters:

	js	[out] Pointer to a joystick_t structure.
	x	The raw x-axis value.
	y	The raw y-axis value.

void calculate_gforce	(	struct accel_t *	ac,
		struct vec3b_t *	accel,
		struct gforce_t *	gforce
	)

Calculate the gravity forces on each axis.

Parameters:

	ac	An accelerometer (accel_t) structure.
	accel	[in] Pointer to a vec3b_t structure that holds the raw acceleration data.
	gforce	[out] Pointer to a gforce_t structure that will hold the gravity force data.

void calculate_orientation	(	struct accel_t *	ac,
		struct vec3b_t *	accel,
		struct orient_t *	orient,
		int	smooth
	)

Calculate the roll, pitch, yaw.

Parameters:

	ac	An accelerometer (accel_t) structure.
	accel	[in] Pointer to a vec3b_t structure that holds the raw acceleration data.
	orient	[out] Pointer to a orient_t structure that will hold the orientation data.
	rorient	[out] Pointer to a orient_t structure that will hold the non-smoothed orientation data.
	smooth	If smoothing should be performed on the angles calculated. 1 to enable, 0 to disable.

Given the raw acceleration data from the accelerometer struct, calculate the orientation of the device and set it in the orient parameter.
