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

Part 3
한국어 전문 번역
설명
이 sample application은 sensor temperature, acceleration과 angular velocity를 0.5 Hz로 주기적으로 측정하고, system 시작 후 경과한 timestamp와 함께 값을 console에 표시합니다.
Triggered mode를 활성화하면 sensor가 measurement를 생성하는 rate에 맞춰 값을 표시합니다.
배선
이 sample은 외부 sensor breakout을 사용합니다. Sensor가 연결된 I2C bus와 sensor 제어에 쓰는 GPIO를 식별하는 Devicetree overlay를 제공해야 합니다.
빌드 및 실행
Sensor 위치를 지정하는 Devicetree overlay를 준비한 뒤 다음 명령으로 sample application을 build하고 flash합니다.
