How are the GetxPhys and GetyPhys functions supposed to work, I'm using the TOUCH_Calibrate.c sample which makes use of the functions, but they always return 0.
GUI_PID_STATE State;
int px, py;
GUI_TOUCH_StoreState(50, 50);
GUI_TOUCH_GetState(&State);
px = GUI_TOUCH_GetxPhys();
py = GUI_TOUCH_GetyPhys();
// State.x == State.y == 50
// px == py == 0
In practise I call StoreState repeatedly from an interrupt, but I thought perhaps there was an issue with interrupts so I made the above code to test. Any ideas on what I am doing wrong?
