- LIS2DW12 Triple Axis Accelerometer x1
- Jumper wires x1
-
Software
- Arduino IDE
- Download and install the LIS Series Library and Sample Code. (About how to install the library?)
- About how to use Firebeetle Board-M0?
Connection
Connect your sensor to M0 controller.
Sample code 1-Read acceleration of x, y and z(getAcceleration.ino)
- Select getAcceleration.ino
- Program Burning
/**！
* @file getAcceleration.ino
* @brief Get the acceleration in the three directions of xyz, the range can be ±2g, ±4g, ±8g or ±16g, set by the setRange() function
* @n In this example, the continuous measurement mode is selected by default -- the acceleration data will be measured continuously according to the measuring rate.
* @n You can also use the single data conversion on demand mode 1. You need to select a suitable conversion mode in the setPowerMode() function
* @n 2. Fill in the setDataRate() function with the eSetSwTrig parameter
* @n 3. Request a measurement by the demandData() function
* @n When using SPI, chip select pin can be modified by changing the value of LIS2DW12_CS
