How to setup timer resolution to 0.5 ms?

Question

I want to set a machine timer resolution to 0.5ms.

Sysinternal utility reports that the min clock resolution is 0.5ms so it can be done.

P.S. I know how to set it to 1ms.

P.P.S. I changed it from C# to more general question (thanks to Hans)

System timer resolution

Answer 1

Timer.Interval = 500;

Answer 2

You'll need a high resolution timer for it.. You can find some information here: http://www.codeproject.com/KB/cs/highperformancetimercshar.aspx

EDIT: More information can be found here: set to tenth of millisecond; http://msdn.microsoft.com/en-us/library/aa964692(VS.80).aspx

Answer 3

The best you can get out the Win32 API is one millisecond with timeBeginPeriod and timeSetEvent. Maybe your HAL can do better but that's academic, you cannot write device driver code in C#.
