Implements all features of STMicroelectronics LIS331HH accelerometer and most of the features of LIS3DH according to their data sheet. Scales:
- LIS331HH: ±6g/±12g/±24g
- LIS3DH: ±2g/±4g/±8g/±16g
The code uses the I²C protocol to communicate with the sensor. If you attach the sensor to a 5V Arduino board, please consider using a bi-directional level shifter.
| LIS331 pin | Arduino Nano pin | Description |
|---|---|---|
| GND | GND | |
| INT2 | D3 | Optional, pin should be interrupt-capable |
| INT1 | D2 | Optional, pin should be interrupt-capable |
| SDA | A4 | Serial data |
| SCL | A5 | Serial clock |
| SA0 | 3V3 or GND | Least significant bit of the device address |
| CS | 3V3 | Selects I²C protocol over SPI |
| VCC | 3V3 |
Install I2C Master Library. It's faster, more robust, and customisable than the built-in Wire.h library.
