Torsten Rasmussen 1cccc8a8fe cmake: increase minimal required version to 3.20.0 Move to CMake 3.20.0. At the Toolchain WG it was decided to move to CMake 3.20.0. The main reason for increasing CMake version is better toolchain support. Better toolchain support is added in the following CMake versions: - armclang, CMake 3.15 - Intel oneAPI, CMake 3.20 - IAR, CMake 3.15 and 3.20 Signed-off-by: Torsten Rasmussen <Torsten.Rasmussen@nordicsemi.no>		2021-08-20 09:47:34 +02:00

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:

.. zephyr-app-commands::
   :zephyr-app: samples/sensor/mpu6050
   :board: nrf52dk_nrf52832
   :goals: build flash
