4 Sensor fusion is a process by which data from several different sensors are fused to compute something more than could be determined by any one sensor alone. An example is computing the orientation of a device in three dimensional space. That orientation is then used to alter the perspective presented by a 3D GUI or game.
6 The NXP Sensor Fusion Library for Kinetis MCUs (also referred to as Fusion Library or development kit) provides advanced functions for computation of device orientation, linear acceleration, gyro offset and magnetic interference based on the outputs of NXP inertial and magnetic sensors.
8 Version 7.00 of the sensor fusion development kit has the following features:
10 * Full source code for the sensor fusion libraries
11 * IDE-independent software based upon the NXP Kinetis Software Development Kit (KSDK).
12 * The Fusion Library no longer requires Processor Expert for component configuration.
13 * Supports both bare-metal and RTOS-based project development. Library code is now RTOS agnostic.
14 * Optional standby mode powers down power hungry sensors when no motion is detected.
15 * 9-axis Kalman filters require significantly less MIPS to execute
16 * All option require significantly less memory than those in the Version 5.xx library.
17 * Full documentation including user manual and fusion data sheet
