X-NUCLEO-IKS01A1: MEMS inertial and environmental multi-sensor shield
#####################################################################

Overview
********
This sample enables all sensors of a X-NUCLEO-IKS01A1 shield, and then
periodically reads and displays data from the shield sensors:

- HTS221: Temperature and humidity
- LPS25HB: Atmospheric pressure
- LIS3MDL: 3-axis Magnetic field intensity
- LSM6DSL: 3-Axis Acceleration

Requirements
************

This sample communicates over I2C with the X-NUCLEO-IKS01A1 shield
stacked on a board with an Arduino connector. The board's I2C must be
configured for the I2C Arduino connector (both for pin muxing
and device tree).

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

This sample runs with X-NUCLEO-IKS01A1 stacked on any board with a matching
Arduino connector. For this example, we use a :ref:`nucleo_f429zi_board` board.
