I'm using the STM32F401RE Nucleo board, I have noticed that the internal clock HSI has a quite high inaccuracy over temperature and it's not suitable for my application.

I want to use an external clock for the board but I don't know how to properly install and configure the external clock?

And in STM32Cubemx, when selecting SMT32F401RE Nucleo board, in "Clock Configuration" tab, it's not possible for choosing the HSE clock, only HSI clock available.


Any example on how to use external clock source would be great for me.
