Gerard Marull-Paretas 93b63df762 samples, tests: convert string-based twister lists to YAML lists Twister now supports using YAML lists for all fields that were written as space-separated lists. Used twister_to_list.py script. Some artifacts on string length are due to how ruamel dumps content. Signed-off-by: Gerard Marull-Paretas <gerard.marull@nordicsemi.no>		2023-05-10 09:52:37 +02:00

Description
***********

This sample application configures the accelerometer and gyroscope to
measure data at 100Hz. The result is written to the console.

Wiring
*******

This sample uses the BMI270 sensor controlled using the I2C interface.
Connect Supply: **VDD**, **VDDIO**, **GND** and Interface: **SDA**, **SCL**.
The supply voltage can be in the 1.8V to 3.6V range.
Depending on the baseboard used, the **SDA** and **SCL** lines require Pull-Up
resistors.

Building and Running
********************

This project outputs sensor data to the console. It requires a BMI270
sensor. It should work with any platform featuring a I2C peripheral interface.
It does not work on QEMU.
In this example below the :ref:`nrf52840dk_nrf52840` board is used.
