標題: stm32F407的按鍵FIFO應(yīng)用 源程序
參考并理解安富萊的代碼，能有按下，彈起和長按，并且長按可以連發(fā)，在程序里修改就可以

單片機源程序如下:

  3. /* Includes ------------------------------------------------------------------*/

  10. #include "KeyFIFO.h"
  11. /* USER CODE END Includes */

  14. /* USER CODE BEGIN PTD */

  16. /* USER CODE END PTD */

  18. /* Private define ------------------------------------------------------------*/
  19. /* USER CODE BEGIN PD */

  21. /* USER CODE END PD */

  23. /* Private macro -------------------------------------------------------------*/
