어제 만들었던 00_BASIC 파일을 복사하고 01_LED라는 이름으로 바꾼 후 붙여넣기를 한다.

먼저 stm32 보드에 있는 led가 작동되는지 확인하기 위해 속도를 달리하여 테스트를 2번 해본다.
이번에는 400 delay의 속도로 테스트해본다.

{
HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_5);
HAL_Delay(1000);
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}
이번에는 1000 delay의 속도로 테스트해본다.
다음으로, led bar를 사용하여 led를 2개 제어해보자.
STM32cubeide 진행 과정은 위의 LED와 똑같고, Output을 하나 더 추가로 설정한다.
