3_STM32cubeIDE_函数跳转,快速注解,USART(通用同步异步收发机)

1_函数跳转

---

按住键盘ctrl键不放，然后用鼠标单击函数名，这样就能跳转到函数体当中。(结构体，枚举，数组等同样适用)

2_快速注解

---

快捷键ctrl+/

  /* USER CODE BEGIN Init */

  /* USER CODE END Init */

  /* Configure the system clock */

  /* USER CODE END 2 */

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
	    HAL_UART_Transmit(&huart2,data,6,10);  //第三个参数:本次要发送的字符数量;第四个参数单位是ms
		  HAL_Delay(1000);
	  }
  /* USER CODE END 3 */
