Edge counting with digitial pause trigger

[Rajaram]

Hi Again,

It was not a big issue. I removed the error handler from the program and it is working fine. Error 0 stands for " Operation completed successfully" in VB.

Thanks

Hello there

Now I will explain abt the problem

1) Buffer operation

I would like to do single buffer operation (finite)

function in traditional DAQ is

  i6602Status = GPCTR_Change_Parameter(i6602DeviceNum, lCounter, ND_BUFFER_MODE, ND_SINGLE)

Is there any function in DAQmx to set up single buffer operation?

2) I would like to configure the buffer

function in traditional DAQ is

i6602Status = GPCTR_Config_Buffer(i6602DeviceNum, lCounter, 0, Int(MCS_ChannelsPerSweep.Text), pulBuffer(1)

Shd I configure the buffer when i do buffer operation or will be done automatically when calling the buffer operation? If not is there any function in DAQmx to configure buffer operation?

3) Setting up hardware trigger and software trigger

traditional DAQ function:

            Hardware trigger:

            i6602Status = GPCTR_Change_Parameter(i6602DeviceNum, lCounter, ND_START_TRIGGER, ND_ENABLED)

           Software Trigger:

           i6602Status = GPCTR_Change_Parameter(i6602DeviceNum, lCounter, ND_START_TRIGGER, ND_AUTOMATIC)

Is there any function in DAQmx to set up different trigger?

Thanks

Hey there,

Sorry I haven't got back to you in a while.  I resolved this issue and I stopped receiving the notifications.  Only just checked it "just in case" and see that you are still posting new questions.  I'll look into the questiuons and get back to you as soon as I can.

Thanx

Hello Adam,

Thanks for your response. I have been totally lost in this MCS acquisition, it will be great if i get assistance as this is the last part of the project.

Thanks

Hey,

You might want to have a look at the help file that details all of the counter commands etc.

If you go to >>Start >> Programs>>National Instruments>>NI-DAQ>> NI-DAQmx C API Visual Basic 6.0 Help

There is a load of information in there that will help you look into the problem.  Its going to take me quite a while to look into this as I am not really all that familiar with traditional Daq Counters.

It might even be worth starting a new thread.  More people will look at new threads than 3 week old ones.

Thanx

AdamB

p.s What is MCS?

Hi

I had a look at the help and it does not having any information about

1) buffer event counting (synchronous)

2) hardware trigger and software trigger

3) configuring buffer event counting

But these are the functions i have listed out before

Thanks

In that help file there is a DAQmc C Reference help guide.

Did you look in there?

Try posting in a new forum.  It really might help you get other people that have used these before.
