[질문/해결완료] configUSE_IDLE_HOOK를 1로 설정시 기존 task printf 문 동작 불가능

idle hook 함수에서 출력량을 줄여주었더니 아래와 같이 정상 동작합니다.

반영한 source:

void vApplicationIdleHook (void)
{
#if (defined (cms_enable_print_at_idel_hook) && ( cms_enable_print_at_idel_hook == 1))
	printf("T1 %d, T2 %d, T3 %d, Idle %d\n", task1timer, task2timer, task3timer, idletimer);
#else
    if(idletimer % 100000 == 0)
    {
        printf("."); fflush(stdout);
    }
    idletimer++;
#endif
}

안녕하세요. chucky2님!

모두 화면에 출력되었지만, 압도적인? printf(".") 출력량 때문에 다른 내용들은 가려서 보이지 않았을 겁니다. 아래 코드를 참고하여 테스트 해보시고 결과를 알려주세요.

void vApplicationIdleHook (void)
{
	idletimer++;
	if(idletimer % 1000 == 0)
	{
		printf("."); fflush(stdout);
	}
}

혹시 필요하실지 몰라 전체 소스(task.c)를 올려드립니다.
