Fermion: I2C LIS331HH Triple Axis Accelerometer Sensor

1. Example Code for Arduino-M0-Wakeup function

This example demonstrates 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. Connect INT1/INT2 to the board’s interrupt pin. SPI CS can be modified via LIS331HH_CS.

2. Example Code for Arduino-M0-External interrupt function

This example demonstrates interrupt detection. When acceleration on a selected axis exceeds or falls below the set threshold, the interrupt signal can be detected on the INT1/INT2 pin.

3. Example Code for Arduino-M0-Read acceleration of x, y and z

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.

4. Example Code for Raspberry Pi-Wakeup function

Wakeup function (Only available for Breakout Version).

5. Example Code for Raspberry Pi-External interrupt function

External Interrupt Function.

6. Example Code for Raspberry Pi-Read acceleration of x, y and z

Read acceleration of x, y and z.
