标题: STM32 cubemx配置工程-LED代码
自己刚比赛完发现了很多不会的东西
现在好多东西都需要重新学习一下

因此上传写基础的代码代表自己学习的进度



单片机源程序如下:
  1. /* Includes ------------------------------------------------------------------*/
  2. #include "stm32f4xx_hal.h"
  3. #include "gpio.h"

  5. /* USER CODE BEGIN Includes */

  7. /* USER CODE END Includes */

  9. /* Private variables ---------------------------------------------------------*/

  11. /* USER CODE BEGIN PV */
  12. /* Private variables ---------------------------------------------------------*/

  14. /* USER CODE END PV */

  16. /* Private function prototypes -----------------------------------------------*/
  17. void SystemClock_Config(void);

  19. /* USER CODE BEGIN PFP */
  20. /* Private function prototypes -----------------------------------------------*/

  22. /* USER CODE END PFP */

  24. /* USER CODE BEGIN 0 */

  28. int main(void)

  43.   /* Initialize all configured peripherals */
  44.   MX_GPIO_Init();

  46.   /* USER CODE BEGIN 2 */
