Enumeration Type Documentation

enum el_accelerometer_output

This enum is used in el_accelerometer_get to select the output type to get.

Enumerator
EL_ACCELERATION_X	get the acceleration along x-axis
EL_ACCELERATION_Y	get the acceleration along y-axis
EL_ACCELERATION_Z	get the acceleration along z-axis
EL_ACCELERATION_ALL_3V	get the acceleration along all three axes

Function Documentation

int el_accelerometer_get	(	el_index	i,
		el_accelerometer_output	u,
		el_int16 *	out
	)

get output value(s) from a accelerometer

Parameters

i	index of the accelerometer (currently can only be 0)
u	output type
out	pointer to a variable or an array of variables to store the output value(s).

Returns

number of values stored into *out.

The refreshing rate of the accelerometer outputs is 120 Hz.
