[질문]펄스 만들기.....

음.. 이게 맞는지 몰겟군요.... 험험..
예전에 LCD 컨트롤 하믄서 섰던건데.. 물론 open source 졍 ㅋㅋ
uPause (int delayCalls)
{
#if defined DELAY_GETTIMEOFDAY
struct timeval current_time,delay_time,wait_time;

// Get current time first thing
gettimeofday(&current_time,NULL);

// Calculate when delay is over
delay_time.tv_sec = 0;
delay_time.tv_usec = delayCalls;
timeradd(&current_time,&delay_time,&wait_time);

do {
gettimeofday(&current_time,NULL);
} while (timercmp(&current_time,&wait_time,<));

#elif defined DELAY_NANOSLEEP
struct timespec delay,remaining;

delay.tv_sec = 0;
delay.tv_nsec = delayCalls * 2100; //org 1000
while ( nanosleep(&delay,&remaining) == -1 )
{
delay.tv_sec = remaining.tv_sec;
delay.tv_nsec = remaining.tv_nsec;
}
#else
int i;
for (i = 0; i < delayCalls; ++i)
port_in (port);
//TODO: put in option for nanosleep rather than dummy I/O call
#endif
}

이게 아니믄 할수 업구용.. 이게 맞았으면 좋겟네용...
그럼 수고하세용
아참 코드 올릴때 bbcode 쓰라고했는데 그거 어케 쓰는건지.. 쩝.
