Hi @VLau ,
Could you try this ? Works on my side, I based it on your code, the main difference was that I added the ft6x06_ReadID() calls, and instead of doing everything in init() and sampleTouch() I added extra steps to make sure the program had time to extract and use the right information (if that makes sense :grinning_face_with_sweat:).

and in STM32TouchController.hpp just add the two functions TS_init() and TS_getCoordinates() I added

{
public:
STM32TouchController() {}
/**

virtual void init();

Hope this helps (and also works on your side),
