MPU9250_Basic
Basic example sketch for MPU-9250 DMP Arduino Library
Jim Lindblom @ SparkFun Electronics
original creation date: November 23, 2016
https://github.com/sparkfun/SparkFun_MPU9250_DMP_Arduino_LibraryThis example sketch demonstrates how to initialize the
MPU-9250, and stream its sensor outputs to a serial monitor.Development environment specifics:
Arduino IDE 1.6.12
SparkFun 9DoF Razor IMU M0Supported Platforms:
- ATSAMD21 (Arduino Zero, SparkFun SAMD21 Breakouts)

// INV_XYZ_GYRO, INV_XYZ_ACCEL, INV_XYZ_COMPASS,
// INV_X_GYRO, INV_Y_GYRO, or INV_Z_GYRO
// Enable all sensors:
imu.setSensors(INV_XYZ_GYRO | INV_XYZ_ACCEL | INV_XYZ_COMPASS); // Use setGyroFSR() and setAccelFSR() to configure the
// gyroscope and accelerometer full scale ranges.
// Gyro options are +/- 250, 500, 1000, or 2000 dps
imu.setGyroFSR(2000); // Set gyro to 2000 dps
// Accel options are +/- 2, 4, 8, or 16 g

// Note: the MPU-9250's magnetometer FSR is set at
// +/- 4912 uT (micro-tesla's) // setLPF() can be used to set the digital low-pass filter
// of the accelerometer and gyroscope.
// Can be any of the following: 188, 98, 42, 20, 10, 5
// (values are in Hz).

// setSampleRate. Acceptable values range from 4Hz to 1kHz
