Resources and Going Further

For more information about the MPU-9250 Breakout, check out the links below.

Many of the advanced features of the MPU-9250 are only accessable by agreeing to a pages of licensing terms and logging in as a developer to get access to Embedded MotionDriver 6.12. This approach isn't super Arduino friendly. At power up 3062 bytes of undocumented hex needs to be loaded into the MPU-9250.

#define DMP_CODE_SIZE           (3062)

static const unsigned char dmp_memory[DMP_CODE_SIZE] = {
    /* bank # 0 */
    0x00, 0x00, 0x70, 0x00, 0x00, 0x00, 0x00, 0x24, 0x00, 0x00, 0x00, 0x02, 0x00, 0x03, 0x00,
    0x00, 0x00, 0x65, 0x00, 0x54, 0xff, 0xef, 0x00, 0x00, 0xfa, 0x80, 0x00, 0x0b, 0x12, 0x82,...

Code snippet of MPU-9250 Embedded MotionDriver firmware

That binary combined with the driver and any code that does something with the sensor data quickly maxes out smaller microcontrollers. Feel free to register and play around if you want to take this product further.

A customer of ours shared his great tutorial on Affordable 9-DoF Sensor Fusion. Check it out for more info on sensor fusion.
