LED On/Off #6

이제 부터 응용이다.

사실 코딩을 오래한 사람들은 그냥 넘어 가기 바란다.

사실 코딩만 30년 한사람의 입장에서는 별로 그다지, 큰 의미가 있는것은 아니다.

그래도 초보라면 여러가지 응용을 하기 바란다.

led가 왔다 갔다 하던지 led가 움지이게 하던지 

창의적인 발생은 무궁 무진하다.

여기서 하는것은 그냥 단지 예시일 뿐이다.

추가한 소스코드는 아래와 같다.

 

  HAL_GPIO_WritePin(LED7_GPIO_Port, LED7_Pin|LED6_Pin|LED5_Pin|LED4_Pin, GPIO_PIN_RESET);
  HAL_GPIO_WritePin(LED3_GPIO_Port, LED3_Pin|LED2_Pin|LED1_Pin|LED0_Pin, GPIO_PIN_RESET);
  
  
  void StartDefaultTask(void *argument)
{
  /* USER CODE BEGIN 5 */
  /* Infinite loop */
	  for(;;)
	  {
	    // 메인 로직이 들어갈 곳 (비워두거나 시스템 모니터링 등 수행)

		  for (int i=0; i<=6; i++)
		  {
			  for (int j=0; j<=7; j++)
			  {
				  HAL_GPIO_WritePin(led_port[j], led_pin[j], i==j);
			  }
			  HAL_Delay(100);
		  }

		  for (int i=7; i>=1; i--)
		  {
			  for (int j=0; j<=7; j++)
			  {
				  HAL_GPIO_WritePin(led_port[j], led_pin[j], i==j);
			  }
			  HAL_Delay(100);
		  }
	  }
  /* USER CODE END 5 */
}

 

 

전체코드도 다시 기술 한다.
