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.

In this example, I use the ATMega328PU that comes on the classic Arduino Uno board. This MCU has three timers, and the delay(), millis(), and micros() functions use timer0. Therefore, your sketch should use timer1 (16-bit) or timer2 (8-bit).

Web5 mag 2024 · So is timer 2 responsible for the delay() and delaymicroseconds() on mega? No, Timer0 is used on the mega for millis() and micros(). delay() uses the millis counts based on Timer0. delaymicroseconds() does not use a timer. It works on processor cycles.

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 ... WebThis timer provides a way to use time delays without blocking the processor, so it can do other things while the timer ends up. This is called a non-blocking delay timer. The timer provides basic functionality to implement different ways of timing in a sketch. There are two main ways to use the timer, first as a Start-Stop-Reset timer.
