If you are looking for 'busy wait' routines, then you might have a look at the McuWait (.c and .h) in https://github.com/ErichStyger/McuOnEclipseLibrary/tree/master/lib/src This is what I use, and it provides busy waiting with cycles, milliseconds and microseconds. It uses ...
Arduino Delay milliseconds You have seen the function delay() which takes one parameter representing milliseconds. Arduino Delay microseconds Another function you can use delayMicroseconds() which again takes a parameter but this time representing micro seconds. Each microsecond is a millionth of a seco...

In this case, using delay(1500) in your setup() function is perfectly fine. Basically, any delay() in the setup() function of your Arduino program won’t be a problem. As explained in the delayMicroseconds() part, you need to wait for a few microseconds (not milliseconds!) ...
register.Thus,at aCPUspeed of1MHz,delays of up to768microseconds can be achieved. 这是文件里对这个函数的解释,很明显,在uno的16MHz的晶振的加持下,该函数的最小延时为48us。 同理,另一个函数是void _delay_loop_2(uint16_t __count),注释我就不贴了,这是个用16位的counter实现的ms级别的delay函数...
When using unsigned values, if you do the math in the right place, the overflow takes care of itself. So I think your first option could look like this: Code: Select all void delay_us(uint64_t number_of_us) { uint64_t microseconds = (uint64_t)esp_timer_get_time(); if (number...
noteOn(0, 60, 100); MidiUSB.flush(); delay(200); noteOff(0, 52, 100); noteOff(0, 53, 100); noteOff(0, 57, 100); noteOff(0, 60, 100); MidiUSB.flush(); delay(200); } 25 microseconds is not quite enough: Thanks for your help....
in various applications. Designed with the NE555 chip, this module offers a wide range of timing from microseconds to long hours, making it suitable for diverse scenarios. Whether you're looking to prevent car ignition, safeguard against high current surges, or manage the timing of various ...
Now doing the math, each clock cycle lasts 0.000128 seconds or 128 microseconds. The math checks out, 7812.5 Hz(0.000128s)= 1. So we know that 7812.5 clock cycles out of the 65536 is what is needed to get a 1-second delay. As long as the count that the timer can do exceeds the ...
by microseconds properly. I think I have a timer set up wrong, but can't figure it out. For instance, If i set the rawcode to all 1uS, the output on my scope is closer to steps of something like 33us. If I have a "10" in the raw codes, I want a 460khz pulse for 10us....
