A bare-bones library for interacting with the LSM6DSOX accelerometer using STM32 HAL in CubeMX.
I've tested it with my LSM6DSOX breakout board connected to my STM32F04 debug board via I2C.
I have not yet needed the SPI interface, so that is not yet implemented in this library!
Place the .h and .c files in your Core/Inc and Core/Src.
- Include the library.
/* USER CODE BEGIN Includes */
#include "lsm6dsox.h"
/* USER CODE END Includes */
- Allocate storage.
/* USER CODE BEGIN PV */
// Allocate a buffer for reading data from the sensor.
uint8_t lsm6dsox_buf[6] = { 0 };
// New instance of the lsm6dsox convenience object.
lsm6dsox_t lsm6dsox;
// lis3dh calls return this HAL status type.
HAL_StatusTypeDef status;
/* USER CODE END PV */
- Initialize the device.
Assumes you have configured your project to use I2C. This will generate I2C_HandleTypeDef hi2c1;.
The init function is not very clever. It only does things I've so far had a use for.
One important detail is that there's no way to configure the alternate I2C address. So definitely fix that if you need it.
/* USER CODE BEGIN 2 */
status = lis3dh_init(&lis3dh, &hi2c1, xyz_buf, 6);
if (status != HAL_OK) {
// Unable to communicate with device!
}
/* USER CODE END 2 */
- Etc.
