Clock Configuration with STM32CubeIDE
I am new ti STM32CubeIDE
I am trying to use the visual clock configuration tool.
What I can't figure out is how do I select HSE in the PLL Source Mux? It seems to be disabled in the tool.

You must enable it in the "Pinout & Configuration" tab (the main tab) under "System Core -> RCC"
