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 nrf52dk_nrf52832 samples/sensor/mpu6050
west flash
