◆ calculate_gforce()

void calculate_gforce ( struct accel_t ac,
struct vec3w_t accel,
struct gforce_t gforce 
)

Calculate the gravity forces on each axis.

Parameters
acAn accelerometer (accel_t) structure.
accel[in] Pointer to a vec3w_t structure that holds the raw acceleration data.
gforce[out] Pointer to a gforce_t structure that will hold the gravity force data.

◆ calculate_orientation()

void calculate_orientation ( struct accel_t ac,
struct vec3w_t accel,
struct orient_t orient,
int  smooth 
)

Calculate the roll, pitch, yaw.

Parameters
acAn accelerometer (accel_t) structure.
accel[in] Pointer to a vec3w_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.
smoothIf 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.
