@par 例程描述 

本例演示如何使用TIM1测量外部信号的频率和占空比。

本例程系统时钟工作在24Mhz。

TIM1 使用PD4管脚进行外部信号频率和占空比的测量
TIM2 输出4路频率相同，占空比不同的PWM波供TIM1测量使用
  TIM2_CH1 PB5 10kHz  35%
  TIM2_CH2 PD6 10kHz  70%
  TIM2_CH3 PA3 10kHz  28%
  TIM2_CH4 PC4 10kHz  95% 


@par 目录内容 

  - TIM/TIM1_PWM_Input/TIM1_PWM_Input.uvprojx   MDK5工程文件
  - TIM/TIM1_PWM_Input/TIM1_PWM_Input.uvoptx    MDK5工程配置文件
  - TIM/TIM1_PWM_Input/JLinkSettings.ini        Jlink配置文件
  - TIM/TIM1_PWM_Input/main.c                   主程序


@par 硬件和软件环境

  - 硬件平台搭建
    - 芯片管脚连接如下：
      - TIM1_CH1  PD4 连接到外部波形管脚(PB5, PD6, PA3, PC4)
