标题: STM32利用STM32CUBEMX调用HAL库实现LED翻转
学习单片机的第一项都是点灯，而STM公司提供了一套软件可以直接生成代码模板，利用代码模板添加自己的代码调库即可完成项目。故学习之。只做学习分享用途。
作用：利用HAL函数实现LED状态翻转

单片机源程序如下:
  1. #include "main.h"
  2. #include "gpio.h"


  5. void SystemClock_Config(void);
  6. /* USER CODE BEGIN PFP */

  8. /* USER CODE END PFP */

  10. /* Private user code ---------------------------------------------------------*/
  11. /* USER CODE BEGIN 0 */

  13. /* USER CODE END 0 */

  15. /**
  16.   * @brief  The application entry point.
  17.   * @retval int
  18.   */
  19. int main(void)

  21.   /* USER CODE BEGIN 1 */

  23.   /* USER CODE END 1 */

  25.   /* MCU Configuration--------------------------------------------------------*/

  27.   /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  28.   HAL_Init();

  30.   /* USER CODE BEGIN Init */

  35.   SystemClock_Config();

  39.   /* USER CODE END SysInit */

  42.   MX_GPIO_Init();
  43.   /* USER CODE BEGIN 2 */

  45.   /* USER CODE END 2 */

  47.   /* Infinite loop */
  48.   /* USER CODE BEGIN WHILE */

都行，最小系统也可以
