I got a nucleo STM32WB55 and a LPS22HB click board from Mikroe.
I generate with Cube-MX a Projekte including the lps22hb mems driver.
so what i know have in the Project:
app_x-cube-mems1.h/.c files
custom_mems_conf.h
lps22hb_reg.h/.c
lps22hb.h/.c
i search on the ST sides to find an example or an description how to use the MEMS-driver for the LPS22HB.
in the custom_mems_conf.h
i found the custom settings:
/* USER CODE BEGIN 1 */
#define USE_CUSTOM_ENV_SENSOR_LPS22HB_0 1U
/* USER CODE END 1 */
#define CUSTOM_LPS22HB_0_I2C_Init BSP_I2C1_Init
#define CUSTOM_LPS22HB_0_I2C_DeInit BSP_I2C1_DeInit
#define CUSTOM_LPS22HB_0_I2C_ReadReg BSP_I2C1_ReadReg
#define CUSTOM_LPS22HB_0_I2C_WriteReg BSP_I2C1_WriteReg
in the lps22hb driver i found the init and read funktion
int32_t LPS22HB_Init(LPS22HB_Object_t *pObj);
int32_t LPS22HB_PRESS_Enable(LPS22HB_Object_t *pObj);
int32_t LPS22HB_PRESS_Disable(LPS22HB_Object_t *pObj);
int32_t LPS22HB_PRESS_GetOutputDataRate(LPS22HB_Object_t *pObj, float *Odr);
int32_t LPS22HB_PRESS_SetOutputDataRate(LPS22HB_Object_t *pObj, float Odr);
int32_t LPS22HB_PRESS_GetPressure(LPS22HB_Object_t *pObj, float *Value);
int32_t LPS22HB_PRESS_Get_DRDY_Status(LPS22HB_Object_t *pObj, uint8_t *Status);
int32_t LPS22HB_PRESS_Get_FThStatus(LPS22HB_Object_t *pObj, uint8_t *Status);
so how to init the sensor and to get Values from it?
Should i create a new handler?
is CUSTOM_LPS22HB_0_I2C_... already set. should i set this?
what to set in the handler?

Nobodoy knows were to find documants to ST X-Cube-Mems?

Hi @JM??l , being the STM32WB55 based on STM32L4 family MCU, I suggest you to start from the FP-SNS-ALLMEMS1 function pack, which includes the libraries for LPS22HB acquisition with STM32L4. Regards
