X-NUCLEO-IKS01A3: shield (Mode 2) sample

|
Overview
|
|
|
|
|
********
|
|
|
|
|
This sample is provided as an example to test the X-NUCLEO-IKS01A3 shield
|
|
|
|
|
configured in Sensor Hub mode (Mode 2).
|
|
|
|
|
Please refer to :ref:`x-nucleo-iks01a3` for more info on this configuration.
|
|
|
|
|
|
|
|
|
|
This sample enables LIS2DW12 and LSM6DSO sensors. Since all other shield
|
|
|
|
|
devices are connected to LSM6DSO, the LSM6DSO driver is configured in sensorhub
|
|
|
|
|
mode (CONFIG_LSM6DSO_SENSORHUB=y) with a selection of two maximum slaves
|
|
|
|
|
among LPS22HH, HTS221 and LIS2MDL (default is LIS2MDL + LPS22HH).
|
|
|
|
|
|
|
|
|
|
Then sensor data are displayed periodically
|
|
|
|
|
|
|
|
|
|
- LIS2DW12 3-Axis acceleration
|
|
|
|
|
- LSM6DSO 6-Axis acceleration and angular velocity
|
|
|
|
|
- LSM6DSO (from LIS2MDL) 3-Axis magnetic field intensity
|
|
|
|
|
- LSM6DSO (from LPS22HH) ambient temperature and atmospheric pressure
|
|
|
|
|
|
|
|
|
|
Optionally HTS221 can substitute one between LIS2MDL and LPS22HH
|
|
|
|
|
|
|
|
|
|
- LSM6DSO (from HTS221): ambient temperature and relative humidity
|
|

This sample communicates over I2C with the X-NUCLEO-IKS01A3 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
|
2019-10-08 01:37:09 +08:00
|
|
|
and devicetree). See for example the :ref:`nucleo_f401re_board` board

|
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-IKS01A3 stacked on any board with a matching
|
|
|
|
|
Arduino connector. For this example, we use a :ref:`nucleo_f401re_board` board.
