STM32F407 Mcu clock setup

‎2024-04-19 12:45 AM

Hello sir, I have developed MCU clock setup using two functions Mcu_init and mcu_initclock in stm32f407 board. 

Now I want to develop Distribute PLL and get PLL status. Can you help me out. 

I have attached my mcu.c here for your convinience.

If so, please mark the solution in that thread.

This seems to be the same as your previous post:

https://community.st.com/t5/stm32-mcus-boards-and-hardware/stm32f407-clock-setup-using-registers/td-p/663048 

So, again, why not create a working setup using CubeMX - then take the required settings from that?

Then debug your code against the Cube code.
