Hello.... I was using keil 5 that I installed it last year.This year, after refreshing my windows, I had to install keil 5 again, but this time, I have a problem with new version of system_stm32f4xx.c (19-June-2014), and I don't know how to change system clock, I want to use PLL and like to have 168 MHz(I know that my clock is equal to HSI,16MHz)! Could you please help me?
Thanks in advance
In principal you can work that way. However this will be hard.
I suggest that you use an existing example project [such as the CMSIS-RTOS Blinky (STM32F4-Discovery)] and run to main. Then you can see the register values that are written by the SystemClock_Config function and copy these values.
Thank you!
