 In the PC tool section of the downloads, there should be an application called PCScope. If we now open our PCScope tool by double clicking on stm32scope.exe, we will see a nice scope trace that has automatically connected to the COM port that you have just initialised in the stm32f7 board. At the moment you're just picking up random noise that is available on the board which is fairly small in comparison. We now need to attach something to our analog input. The analog input we are using is PA0 which is the top pin of the bottom left header on the underside of the board as shown in the diagram. Once we connect an item to this pin the noise level on the screen will change slightly and as soon as we touch the end of our connected wire to provide additional noise onto the analog input that we are measuring a significant change should be visible in our scope trace as shown on the screen.
