原子哥你好：

我最近在调试STM32F1的内部时钟，但是我如何知道我当前的时钟是不是我想要的吗？

{
            RCC_ClocksTypeDef o;

            RCC_GetClocksFreq(&o);

                     printf("ADCCLK_Frequency = %d\r\n", o.ADCCLK_Frequency);
                     printf("HCLK_Frequency = %d\r\n", o.HCLK_Frequency  );
                     printf("PCLK1_Frequency  = %d\r\n", o.PCLK1_Frequency );
                     printf("PCLK2_Frequency  = %d\r\n", o.PCLK2_Frequency );
                     printf("SYSCLK_Frequency = %d\r\n", o.SYSCLK_Frequency);
      }
