X-NUCLEO-IKS02A1 shield - Standard (Mode 1)

Overview

This sample is provided as an example to test the X-NUCLEO-IKS02A1 shield configured in Standard mode (Mode 1). Please refer to X-NUCLEO-IKS02A1: MEMS Inertial and Environmental Multi sensor shield for more info on this configuration.

This sample enables all sensors of a X-NUCLEO-IKS02A1 shield, and then periodically reads and displays data from the shield sensors:

  • IIS2MDC 3-Axis magnetic field intensity

  • IIS2DLPC 3-Axis acceleration

  • ISM330DHCX 6-Axis acceleration and angular velocity

Requirements

This sample communicates over I2C with the X-NUCLEO-IKS02A1 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 devicetree). See for example the ST Nucleo F401RE board source code:

  • $ZEPHYR_BASE/boards/arm/nucleo_f401re/nucleo_f401re.dts

  • $ZEPHYR_BASE/boards/arm/nucleo_f401re/pinmux.c

Please note that this sample can’t be used with boards already supporting one of the sensors available on the shield (such as disco_l475_iot1) as sensors multiple instances are not supported.

Building and Running

This sample runs with X-NUCLEO-IKS02A1 stacked on any board with a matching Arduino connector. For this example, we use a ST Nucleo F401RE board.
