You can use a delay loop: you delay for one microsecond in each iteration, and do as many iterations as microseconds you have to burn: void delay_us (unsigned long us) { while (us--) _delay_us (1); } There are, however, a few issues with this approach: it takes time to manage the iterations (decrement the counter ... Web26 dic 2015 · When you do delay (1000) your Arduino stops on that line for 1 second. delay () is a blocking function. Blocking functions prevent a program from doing anything else until that particular task has completed. If you need multiple tasks to occur at the same time, you simply cannot use delay (). If your application requires that you constantly ...

"Web5 mag 2024 · Delay relies on a timer interrupt to measure the time. Inside the ISR those are turned off so delay just sits and waits forever for an interrupt that's not coming. When you disable interrupts with cli just before the delay call, you have the same problem. Delay is trying to wait 10 seconds, but from its point of view time is standing still.
