A very simple example of using a generic CountdownTimer that is not related to the user interface. Just a few lines of code. import 'dart:async'; import 'dart:io'; import 'package:multitasking/misc/...

I will give you an example calculation. I will use hex values as it is easier to see where the overflow/underflow happens and we don't have to care about exact numbers. Simple example: Now: ...

Signed overflow is undefined behaviour, unsigned arithmetic is defined (C++ standard) as performed modulo 2^bits_of_your_type, so it technically speaking doesn't overflow. However, this doesn't seem ...

You can wrap Task.Delay() with a Jint promise, e.g. using Jint; internal class Program { private static async Task Main(string[] args) { TaskCompletionSource<object?> tcs = new ...

It's simple to extend the timer using another 32-bit register: if (!++ticks) ++overflow; In ARM assembly, that's just one extra instruction. The overhead in testing is slightly more, but still in ...

Could you please elaborate? Do you mean that unsigned long is simply the wrong data type for the problem or that you don't see the logic bug described in the question? Or something else?

Thanks Andrey, your suggestions are much appreciated. Yes, 490 thousand years will certainly suffice. The application controls truncation of an AC waveform so is very sensitive to timing. I'll just ...

you are using unsigned long so overflow is well defined and I do not see a pro0blom.

and 2) are the same thing. 32-bit time counter + overflow counter is exactly the same as single 64-bit counter; except in single 64-bit case the compiler would do the job for you. It also does ...

If you would like more modern solution (iOS 17+), without the publishing hassle and outdated Combine framework, yet maintaining start/stop functionality, you can use something like this: import ...

why the System.Threading.Timer is loosing so much time approx. 3sec. in 5 min. the reason is race condition - to solve this problem you should marshal the call back to the UI thread either using a ...
