[Nano130] Control MPU9250 Sensor

[size=1.1em]

• Application: This sample code uses Nano130 to control sensor MPU9250.
• BSP Version: Nano100B Series BSP CMSIS v3.03.000
• Hardware: NuEdu-EVB-Nano130
  

This example shows how to use Nano130 to communicate with motion sensor MPU9250 to obtain the motion track and direction of the device.

First, Nano130 initializes MPU9250 through I2C interface, setting the mode as measurement mode, sampling frequency as 125Hz, frequency width as 5Hz, acceleration measurement range ± 2G, angular velocity measurement range ± 2000 DPS.

Then, we can use I2C bus to send out instructions to obtain nine values measured by MPU9250. We can use these values to do some interesting applications. For example, use acceleration and angular velocity values to record the moving track, and use magnetic value to determine the moving direction.
