Access to Current CPU Load Amount?

[hecmar.arreola]

Hi!

I need to setup a quick application for some critical timing I am trying to achieve.  Windows is really quite poor at achieving this.  What I really need is a real-time system, but I have what I have and I need to do what I need to do with it today.

There needs to be critical timing between two digital IO ports (in the msecs) once a switch is thrown.  If the CPU load is below 2%, I have no problems obtaining the timing I desire.  If Windows is butting in trying to do something in the background, my timing goes to poo.

Is there anyway to monitor the CPU load (w/o actually creating too much CPU load by monitoring it) so that my digital IO timing code does not fire until the CPU load is below some threshold?

Thanks!

Hi nic

i guess there is a .NET function which can monitor what you need. i also think there is an example code for it on the ni side, but i don´t remember the location.

i found the location. I think this can help you

Here we go.  There is an example.  SimpleTaskMonitor that will work for me!  Thanks!

Worked perfectly.  I'm getting about 0.5ms of percision in Windows!  Who knew it would be possible .
