Ball and Beam Conrtol Help

[adamkse]

Thanks you very much, I will start modifying it and see how get on 🙂

I cant seem to run that VI.

Error -200077 occurred at Property Node DAQmx Timing (arg 3) in DAQmx Timing (Sample Clock).vi:2->PWM-Counter Output.vi

Possible reason(s):

Measurements: Requested value is not a supported value for this property.

Property: SampQuant.SampMode

You Have Requested: Hardware Timed Single Point

You Can Select: Finite Samples, Continuous Samples

Task Name: _unnamedTask<17>

I guess that my card cannot do some of the clock tasks? 

Edit: When i change the Hardware Timed Single Point option i get this error:

Error -200778 occurred at DAQmx Start Task.vi:2 

Possible reason(s):

Measurements: Sample Mode is set to a value other than Hardware Timed Single Point. This is the only value supported for counter generations when Sample Timing Type is set to Sample Clock.

Change the Sample Mode or the Sample Timing Type.

Property: SampQuant.SampMode

Corresponding Value: Continuous Samples

Property: SampTimingType

Corresponding Value: Sample Clock

Task Name: _unnamedTask<1A>

The code is just an example for a specific device.  You have to make modification as you seet fit for your device.  As a last resort, you can always generate the PWM in a loop (software based).

Thank you, I think I was getting close to what I need. Your help is much appreciated 🙂

No problem.  Let me know what the program look like at the end.

I will do.

Thanks again.

This works but still needs some tuning
