If you want to make your Arduino sleep for 1 minute, or for multiple minutes, then it’s quite easy. Take the number of minutes, multiply it by 60 to get the number of seconds, and then multiply it by 1000 to get the number of milliseconds. will make the program sleep for 3 minutes.

Web2 giorni fa · To prototype I am using Arduino's MKR1400 amd MKR1500 with T-mobile GSM IoT SIM cards. In lab condition everything works perfectly for days but in real life condition I have many issues. The arduino's are installed in electric tour boats under deck and in a steel box so the connection is really bad and I am wondering if this might be the … 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.
Web18 lug 2024 · Typical drift is of the order of 1,000 ppm, and is affected by temperature and aging. You can, however, get a delay which is pretty close to the CPU's idea of one second. In other words, you can get something that is really close to a perfect period of 16,000,000 CPU cycles. If that is what you want, your best bet is to use a timer. Web11 feb 2024 · 1 Answer. Sorted by: 2. 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 ...
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.
