| X-NUCLEO-IKS01A2: MEMS inertial and environmental multi-sensor shield |
| ##################################################################### |
| |
| Overview |
| ******** |
| This sample enables all sensors of a X-NUCLEO-IKS01A2 shield, and then |
| periodically reads and displays data from the shield sensors: |
| |
| - HTS221: Ambient temperature and relative humidity |
| - LPS22HB: Atmospheric pressure and ambient temperature |
| - LSM6DSL: 3-Axis Acceleration and 3-Axis Angular Velocity |
| - LSM303AGR 3-Axis Acceleration and 3-axis Magnetic field intensity |
| |
| Requirements |
| ************ |
| |
| This sample communicates over I2C with the X-NUCLEO-IKS01A2 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 zephyr |
| does not yet support sensors multiple instances. |

| Building and Running |
| ******************** |
| |
| This sample runs with X-NUCLEO-IKS01A2 stacked on any board with a matching |
| Arduino connector. For this example, we use a :ref:`nucleo_f401re_board` board. |
