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. WebI'm trying to determine if the AVR delay functions _delay_us() and _delay_ms() use timers in such a way that I can't use those timers for other functionality in my code. If so, what timer does it use? For reference I'm using an Arduino Uno with ATmega328, but I imagine if it's an AVR function it must work similarly on other devices.
