Arduino library to support the LSM6DSO32 3D accelerometer and 3D gyroscope
This sensor uses I2C or SPI to communicate. For I2C it is then required to create a TwoWire interface before accessing to the sensors:
TwoWire dev_i2c(I2C_SDA, I2C_SCL);
dev_i2c.begin();
For SPI it is then required to create a SPI interface before accessing to the sensors:
SPIClass dev_spi(SPI_MOSI, SPI_MISO, SPI_SCK);
dev_spi.begin();
An instance can be created and enabled when the I2C bus is used following the procedure below:
LSM6DSO32Sensor AccGyr(&dev_i2c);
AccGyr.begin();
AccGyr.Enable_X();
AccGyr.Enable_G();
An instance can be created and enabled when the SPI bus is used following the procedure below:
LSM6DSO32Sensor AccGyr(&dev_spi, CS_PIN);
AccGyr.begin();
AccGyr.Enable_X();
AccGyr.Enable_G();
The access to the sensor values is done as explained below:
Read accelerometer and gyroscope.
int32_t accelerometer[3];
int32_t gyroscope[3];
AccGyr.Get_X_Axes(accelerometer);
AccGyr.Get_G_Axes(gyroscope);
There are several examples with the LSM6DSO32 library.
- LSM6DSO32_HelloWorld: This application provides a simple example of usage of the LSM6DSO32 IMU 6-axis. It shows how to display on a hyperterminal the values of the sensor.
- LSM6DSO32_6DOrientation: This application shows how to use the LSM6DSO32 accelerometer to find out the 6D orientation and display data on a hyperterminal.
- LSM6DSO32_FreeFallDetection: This application shows how to detect the free fall event using the LSM6DSO32 accelerometer.
- LSM6DSO32_Pedometer: This application shows how to use the LSM6DSO32 accelerometer to count steps.
- LSM6DSO32_SingleTap: This application shows how to detect the single tap event using the LSM6DSO32 accelerometer.
- LSM6DSO32_DoubleTap: This application shows how to detect the double tap event using the LSM6DSO32 accelerometer.
- LSM6DSO32_TiltDetection: This application shows how to detect the tilt event using the LSM6DSO32 accelerometer.
- LSM6DSO32_WakeUpDetection: This application shows how to detect the wake-up event using the LSM6DSO32 accelerometer.
