MPU6050: Invensense Motion Tracking Device

Description

This sample application periodically (0.5 Hz) measures the sensor temperature, acceleration, and angular velocity, displaying the values on the console along with a timestamp since startup.

When triggered mode is enabled the measurements are displayed at the rate they are produced by the sensor.

Wiring

This sample uses an external breakout for the sensor. A devicetree overlay must be provided to identify the I2C bus and GPIO used to control the sensor.

Building and Running

After providing a devicetree overlay that specifies the sensor location, build this sample app using:

# From the root of the zephyr repository
west build -b nrf52_pca10040 samples/sensor/mpu6050
west flash
