How to set the IRQ/PIO/DMA transfer mode?

Greetings,

For my thesis I need to compare the real impact on data acquired using different transfer modes in CVI (IRQ, DMA, PIO).

Documentation says I need to use the function DAQmxSetAIDataXferMech (TaskHandle taskHandle, const char [], int32 mode channel), but work as it is just not in my CVI (using CVI 2010, version 10.0.1 (419))

How am I supposed to switch between modes?

Thanks for the reply in advance!

Yours,

Adrian

Hi Adrien,.

You can find this property by using DAQmxSetChanAttribute.

Please find attached the viewed two who will guide you to find the property.

Frome the attributes list select entry Analog-> General Properties-> advanced-> transfer of data and memory-> data transfer mechanism

If you have any questions, feel free to ask here.

Be sure to mark the solutions.

Kind regards

    How to set the printer wireless ad Hoc mode to CP1025nw with automatic stop is off? IE never automatic.

    Thank you very much for your help, if necessary.

    Quite a few questions, send, but I will do what I can to answer them.

    I recommend first to buy a router, even if it's one you won't connect to internet and it network with others your PC and printer. This will give you the best features and the results of what you're trying to do.

    In addition, the automatic stop of the printer function can be disabled and is not affected by the type of connection. Usually, you can go through the configuration Menu and select tools to change the options there on the energy saving features.

    Finally, the auto off function on your computer is a Windows question, but one easy answer. If you're on a laptop, you can right click on the battery in the tray (lower right corner) and change the settings for energy conservation.

    You might be better off installing the printer via the USB cord and alternately inspiring when you use it, but which is not optimal if you are printing only a few documents on an irregular basis. A network connection is the easiest to manage across multiple computers, honesty, but you have certain requirements for this connection and limits as well.

    I hope this information is useful!

    File > VI properties > window running Position (in category list) > custom (in position of menu drop-down).

    then just accept the current position and size (leave the boxes checked) or set values you want directly (uncheck the boxes and fill in the numbers), or physically position and size the façade and use, the "set to current location" button and press "set size" current All that is easier for you.

    I found this link, but still he somehow does not give the right output I desired because it has not started to 0.7778.

    Could someone help me with this issue?

    Farid Ali

    Ridwan,

    Since you have a SISO system, you can try using the screw "Design Control" to convert the transfer function after normalization of State-Space model, you can use a function 'hidden' in the design of control that are used to calculate the original terms of your system. This function will calculate the necessary value to States in order to obtain the desired result, based on the model. If your initial release is zero, the Conversion.vi cd_IC will give you an empty model and to avoid an error, then change its value to zero.

    As an attachment, you have an example and a screw that you allow to use it in 2009 LV.

  • How to set the path of the report in a plugin for model

    I'm trying to figure out how to set the path of the report in a plugin process model. I can't find a way to have access to it. It seems this would be a reasonable thing to do since the plug-ins are for the treatment of the results. Does anyone know how to do this? We generally use the sequential process model, but I try to keep my plug-in as independent as possible.

    Thank you.

    If I understand correctly, you want your plug-in, when enabled, change the settings of all other instances of the report OR plugin as their reports share the same directory that your plug-in is configured to use.

    If so, your plug-in can access and change the settings of all other instances of plugin. All instances are passed to all the points of plugin entries in the subproperty of the plugins of the ModelConfiguration parameter table. You can browse this table. Any element of the array with an equal to "NI_ReportGenerator.seq" Base.SequenceFilename is an instance of the report OR plugin. Its report options are stored in the element under PluginSpecific.Options.

    You can change the report options to what you want. Note that the recall of the ReportOptions model is called from template-plugin Initialize entry point, then you might want to ensure that your changes are applied after that, so they are not replaced. To do this, you could make your changes in the Initialize entry point of your plugin and make sure your plugin runs last. To rotate the last, you can set the FileGlobals.ModelPluginComponentDescription.Default.Base.RunOrder in your file of plug-in with a value greater than 0, for example 1.0 (see Help for TestStand > Fundamentals > process template Architecture > plug-in for the model process Architecture > Structure of the plugin sequence files > plugin model of entry Points > Order Execution of Point of entry at run time).

  • How to set the value of a variable in a cluster in LabVIEW to c#?

    Hi guys, I'm working on a small c# program, which by using the interface provided by LabVIEW.  And I know that, with the help of lv. SetControlValue (name, value) can set a variable just on the front panel. But in my case, there are several groups on the front panel. Then it confused me how to set the variables in these groups. For example, there is a cluster named clusterA and a variable named a., I tried something like this:

    lv.SetControlValue("clusterA.valueA",1);
    

    but it totally inoperable. Everyone has some experience with this sort of thing? Thank you very much!!

    Hey guys, thanks a lot for all your response. I just found a simple way to solve this problem. For example, there is a cluster named "ClusterA", and there are only two witnesses, who are: an int value named "IntA" (default = 10 IntA value) and a string value named "StringA" (by default the StringA = 'abc'). In c#, if you call the method:

    var clusterA is vi (Array). GetControlValue ("ClusterA");

    you will get a table looks like: clusterA = {10, 'abc'}; So if you want to change IntA 123, you simply do:

    clusterA.SetValue (123, 0); 123 the value, 0 is the index of IntA in clusterA, after this clusterA table = {123, 'abc'}

    After that, simply to make the table in LabVIEW using:

    VI. SetControlValue ("ClusterA", clusterA);

    and now you see the LabVIEW, IntA is changed.

  • How to set the voltage on a 3.3 volt NI 9237 module?

    Hello

    How to set the voltage on a 3.3 volt NI 9237 module?

    The voltage is now at 2.5 volts.

    This is my first time with this camera.

    This set of MAX or are there jumpers?

    I want the value of the excitation voltage at 3.3 Volts and do not change.

    The NI 9237 is a NEITHER cDAQ-9172.

    Thank you

    Bill

    Hi POBA,.

    This can be set to your programming environment.  For example, LabVIEW Signal Express, a task of MAX, or a DLL call in a text-based environment.  You want to create a strain, tension Custom with excitement, or any bridge based task in any environment.

    "" "In MAX, right-click on your device and choose create a task" acquire signals "analog input"...

    "" "In LabVIEW, place a DAQ Assistant" acquire signals "analog input"...

    "" "In Signal Express, add a step for Acquire" DAQmx Acquire"analog input"...

    In any C language based, you will want to call a function such as: DAQmxCreateAIVoltageChanWithExcit, DAQmxCreateAIStrainGageChan, DAQmxCreateAIBridgeChan

    You can then specify the Source of Exictation to be internal to 3.3V.

    Best,
