Overview
|
|
|
|
|
********
|
|
|
|
|
This sample is provided as an example to test the X-NUCLEO-IKS02A1 shield
|
|
|
|
|
configured in Sensor Hub mode (Mode 2).
|
|
|
|
|
Please refer to :ref:`x-nucleo-iks02a1` for more info on this configuration.
|
|
|
|
|
|
|
|
|
|
This sample enables IIS2DLPC and ISM330DHCX sensors. Since all other shield
|
|
|
|
|
devices are connected to ISM330DHCX, the ISM330DHCX driver is configured in sensorhub
|
|
|
|
|
mode (CONFIG_ISM330DHCX_SENSORHUB=y) with the IIS2MDC magnetometer as external
|
|
|
|
|
slave.
|
|
|
|
|
|
|
|
|
|
Then sensor data are displayed periodically
|
|
|
|
|
|
|
|
|
|
- IIS2DLPC 3-Axis acceleration
|
|
|
|
|
- ISM330DHCX 6-Axis acceleration and angular velocity
|
|
|
|
|
- ISM330DHCX (from IIS2MDC) 3-Axis magnetic field intensity

|
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 :ref:`nucleo_f401re_board` board
|
|
|
|
|
source code:
|
|
|
|
|
|
|
|
|
|
- :zephyr_file:`boards/arm/nucleo_f401re/nucleo_f401re.dts`
|
|
|
|
|
- :zephyr_file:`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.

|
********************
|
|
|
|
|
|
|
|
|
|
This sample runs with X-NUCLEO-IKS02A1 stacked on any board with a matching
|
|
|
|
|
Arduino connector. For this example, we use a :ref:`nucleo_f401re_board` board.
