*New* clock configuration via CubeMX vs *old* via clock configuration tool

Hi,

I just started a new project with STM32F207 but it should use a lot of software form an older project. Now I created a clock configuration with CubeMX and everything is different than with the old clock configuration tool. Before there was a routine in system_stm32f2xx.c called SetSysClock which initilized what I entered in the excel sheet. Now it is not there any more and I can't even find where the clock system is initialized. There are so many routines includes into my new project. Also other stuff is different like there is no more NVIC_Init. Is there a documentation that explains the structure of the whole HAL and clock configuration esp. ? Thanks Martin

Hi Mr_M_from_G,

Old clock configuration tool is usable only to set the clock parameters and configure it.However, the new tool (CubeMX) is useful to initialize all the peripherals to be involved in your application and manage conflicts mainly in pins assignment.So it is not the same approach used for both of them.You have the following user manuals that may help you to understand Cube approach:-
