STM32+FreeRTOS+CUBEMX_学习笔记（七 ）输入捕获

前言

我们可以利用输入捕获模式来测量脉冲宽度或者测量频率。

1、cube设置

2、函数详解：

/**

  * @brief  Read the captured value from Capture Compare unit 读取通道捕获值

  * @param  htim TIM handle.

  * @param  Channel TIM Channels to be enabled

  *          This parameter can be one of the following values:

  *            @arg TIM_CHANNEL_1: TIM Channel 1 selected

  *            @arg TIM_CHANNEL_2: TIM Channel 2 selected

  *            @arg TIM_CHANNEL_3: TIM Channel 3 selected

  *            @arg TIM_CHANNEL_4: TIM Channel 4 selected

  * @retval Captured value
