code show as below:
RCC_ClocksTypeDef get_rcc_clock; //Get system clock status
RCC_GetClocksFreq(&get_rcc_clock); //When simulating, you can see the clocks of various peripherals in the structure get_rcc_clock
Notice:
The prototype of the structure RCC_ClocksTypeDef in the above code can be found in the library file stm32f10x_rcc.h as follows:
typedef struct
{
uint32_t SYSCLK_Frequency; /*!< returns SYSCLK clock frequency expressed in Hz */
uint32_t HCLK_Frequency; /*!< returns HCLK clock frequency expressed in Hz */
uint32_t PCLK1_Frequency; /*!< returns PCLK1 clock frequency expressed in Hz */
uint32_t PCLK2_Frequency; /*!< returns PCLK2 clock frequency expressed in Hz */
uint32_t ADCCLK_Frequency; /*!< returns ADCCLK clock frequency expressed in Hz */
}RCC_ClocksTypeDef;
