C++ HAL_RCC_GetHCLKFreq函数代码示例

/**
  * @brief This function configures the source of the time base:
  *        The time source is configured to have 1ms time base with a dedicated
  *        Tick interrupt priority.
  * @note This function is called  automatically at the beginning of program after
  *       reset by HAL_Init() or at any time when clock is reconfigured  by HAL_RCC_ClockConfig().
  * @note In the default implementation, SysTick timer is the source of time base.
  *       It is used to generate interrupts at regular time intervals.
  *       Care must be taken if HAL_Delay() is called from a peripheral ISR process,
  *       The SysTick interrupt must have higher priority (numerically lower)
  *       than the peripheral interrupt. Otherwise the caller ISR process will be blocked.
  *       The function is declared as __weak  to be overwritten  in case of other
  *       implementation  in user file.
  * @param TickPriority: Tick interrupt priority.
  * @retval HAL status

     * There are two sentences below the clock tree picture, and it is :
     *  1 : When 'TIMPRE' bit of the RCC_DKCFGR1 register is reset, if APBx prescaler is 1, then TIMxCLK = PCLKx, 
            otherwise TIMxCLK = 2 * PCLKx.
     *  2 : When 'TIMPRE' bit of the RCC_DKCFGR1 register is set, if APBx prescaler is 1,2 or 4, then TIMxCLK = HCLK,
            otherwise TIMxCLK = 4x PCLKx.
        In this example TIM3 input clock (TIM3CLK)  is set to APB1 clock (PCLK1) x2,
        since APB1 prescaler is equal to 4 and 'TIMPRE' bit is reset
          TIM3CLK = PCLK1*2 and  PCLK1 = HCLK/4
          => TIM3CLK = HCLK/2 = SystemCoreClock/2
        To get TIM3 counter clock at 10 KHz, the Prescaler is computed as follows:
        Prescaler = (TIM3CLK / TIM3 counter clock) - 1
        Prescaler = ((SystemCoreClock/2) /10 KHz) - 1

        Note:
         SystemCoreClock variable holds HCLK frequency and is defined in system_stm32f7xx.c file.
         Each time the core clock (HCLK) changes, user had to update SystemCoreClock
         variable value. Otherwise, any configuration based on this variable will be incorrect.
         This variable is updated in three ways:
          1) by calling CMSIS function SystemCoreClockUpdate()
          2) by calling HAL API function HAL_RCC_GetSysClockFreq()
          3) each time HAL_RCC_ClockConfig() is called to configure the system clock frequency
