示例2: main


//.........这里部分代码省略.........
  Timer clock prescalers selection activated (TIMPRE bit from RCC_DCKCFGR register is set).   
  TIM3CLK = 4 * PCLK1  
  PCLK1 = HCLK / 4 
  => TIM3CLK = HCLK = SystemCoreClock

  For TIM3CLK equal to SystemCoreClock and prescaler equal to (5 - 1), TIM3 counter clock 
  is computed as follows:
  TIM3 counter clock = TIM3CLK / (Prescaler + 1)
                     = SystemCoreClock / (Prescaler + 1)
                     = 36MHz

  For ARR equal to (1800 - 1), the TIM3 output clock is computed as follows:
  TIM3 output clock = TIM3 counter clock / (ARR + 1)
                    = 20KHZ
                     
  The TIM3 CCR1 register value is equal to 900, so the TIM3 Channel 1 generates a 
  PWM signal with a frequency equal to 20 KHz and a duty cycle equal to 50%:

  TIM3 Channel1 duty cycle = (TIM3_CCR1/ TIM3_ARR + 1)* 100 = 50%

    Note:
     SystemCoreClock variable holds HCLK frequency and is defined in system_stm32f4xx.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
