LSM303DLHC STM32F411E

Hello everyone,  I am working with the STM32F411E and i am trying to make the LSM303DLHC working on my board. At this moment i am using this lib: https://github.com/STMicroelectronics/STM32CubeL4/blob/master/Drivers/BSP/Components/lsm303dlhc/lsm303dlhc.c

The problem i am having is that it cant find accelero.c to understand the GetXYZ function code in the code AccelerometerDrv->GetXYZ(pDataXYZ);

Hello @ThienNguyen0301 , 

In the accelero.h header file, we define a structure ACCELERO_DrvTypeDef. This structure includes a function pointer GetXYZ that is meant to point to a function which retrieves the x, y, and z acceleration data from the accelerometer.

In the Lsm303dhlc.c source file, we have the implementation of the function LSM303DLHC_AccReadXYZ . This function is specifically written to interact with the hardware to retrieve the accelerometer data.

The GetXYZ function pointer in the ACCELERO_DrvTypeDef structure is set to point to LSM303DLHC_AccReadXYZ. This means that when we call AccelerometerDrv->GetXYZ(pDataXYZ) in the code, it's actually calling the LSM303DLHC_AccReadXYZ function, which will execute and provide us with the accelerometer data.
