Luckily Google is not looking into our HDs (yet?), so people do not find these at first: C:\Users\XXXX\STM32Cube\Repository\STM32Cube_FW_F7_V1.8.0\Projects\STM32746G-Discovery. And so on
So if you put all examples as sticky posts in this forum, it would be much easier to tell users how to get ADC interrupts working. And I am sure there are many harder cases like USB and ETHERNET.
