On this video, its me using STM32CubeIDE, connected directly to the board vis USB in debug mode, manipulating -directly- the register on the board that controls the green led to turn it off and on 🤯. Might not seem much from the video, but just taking in the fact that you can manipulate the CPU and its peripherals directly like that is something that amazes me.
