Hi I have problems with STM32CubeIDE and the initialization of the Sensor vl53L0x, the api I import it to the middleswares folder. The error 'undefined reference to DataInit...'.

Hello @ VDein.1

I would start by asking about your project structure :

Where is this reference to "VL53L0X_DataInit()" located?
Is it linked correctly?
Are the linked files inside the project or somewhere else?
If somewhere else, is those resources linked correctly to the project?

Waiting your feedback !

1. VL53L0X_DataInit() this function is in the API, exactly in VL53L0X_api.h.

2. Well, I think it is well linked. To use the API import the API library in the Middleswares folder. Then I went to the Project properties and there I added the paths, in C/c++ Build/Settings/MCU GCC Compiler/Include paths.

I don't know if this is the correct way to link the API_VL53L0X files.

Thanks for your time.
