    2. Example Code for Arduino-Read Acceleration of XYZ

    Get the acceleration in the three directions of xyz, the range can be ±6g, ±12g or ±24g. When using SPI, chip select pin can be modified by changing the value of LIS331HH_CS.

    3. Example Code for Arduino-Wakeup Function

    This example uses the wake-up function. The module enters low-power mode with a reduced sampling rate and switches to normal mode when an interrupt is triggered.

    4. Example Code for Arduino-External Interrupt Function

    This example demonstrates interrupt detection. An interrupt is triggered when acceleration on the selected axis exceeds or falls below the set threshold, and the signal can be read from INT1/INT2.

    5. Example Code for Raspberry Pi-Wakeup Function

    Use wake-up function (Only available for Breakout Version).

    6. Example Code for Raspberry Pi-Read Acceleration of XYZ

    Get the acceleration in the three directions of xyz.

    7. Example Code for Raspberry Pi-External Interrupt Function

    Interrupt detection (Only available for Breakout Version).
