| :name: LIS2DH Motion Sensor |
| :relevant-api: sensor_interface |
| |
| Get accelerometer data from an LIS2DH sensor (polling & trigger mode). |
| |
| Overview |
| ******** |
| |
| This sample application periodically reads accelerometer data from the |
| LIS2DH sensor (or the compatible LS2DH12, LIS3DH, and LSM303DLHC |
| sensors), and displays the sensor data on the console. |
| |
| Requirements |
| ************ |
| |
| This sample uses the LIS2DH, ST MEMS system-in-package featuring a 3D |
| digital output motion sensor. |

| Building and Running |
| ******************** |
| |
| The LIS2DH2 or compatible sensors are available on a variety of boards |
| and shields supported by Zephyr, including: |
| |
| * :zephyr:board:`actinius_icarus` |
| * :ref:`thingy52_nrf52832` |
| * :zephyr:board:`stm32f3_disco` |
| * :ref:`x-nucleo-iks01a2` |
| |
| See the board documentation for detailed instructions on how to flash |
| and get access to the console where acceleration data is displayed. |
| |
| Building on actinius_icarus |
| =========================== |
| |
| :zephyr:board:`actinius_icarus` includes an ST LIS2DH12 accelerometer which |
| supports the LIS2DH interface. |

| Building on nucleo_l476rg with IKS01A2 shield |
| ============================================= |
| |
| The :ref:`x-nucleo-iks01a2` includes an LSM303AGR accelerometer which |
| supports the LIS2DH interface. This shield may also be used on other |
| boards with Arduino headers. |
