Delay COM port, but it can read back data from MAX

What short RX and RX directly, COM port can data from feedback on the test panel MAX, but still error display "time out What is the reason? Thank you.

Hi Colin,

When you read back the data, there is a parameter called "Bytes read" you need key, the default value is 1024, in this case, it will keep waiting for 1024 bytes until the timeout occur.

I found a good article talk to this topic and you can change the bytes to be read in the test environment LabVIEW or MAX.

Let me know once try you it, thank you.

  • How can I get data from each associated XMLnode in movieclips separated when you click a line in the combobox

    How can I get data from each associated XMLnode in movieclips separated when you click a line in the combobox?

    A sample of XML is like this:

    <>planter

    < Lauvtre >

    < Botanisk_navn > Acer campestre < / Botanisk_navn >

    < Norsk_navn > Naverlonn < / Norsk_navn >

    Gronn < Farge > < / fan >

    H4 < Herdighet > < / Herdighet >

    < Hoyde > 10-15 m < / Hoyde >

    < / Lauvtre >

    I have a combobox where it shows the botanical name and the Norwegian name. But the rest of the info in movieclips seem separate.

    Someone has an idea how to do this? Can I use the trace function maybe? Here is my AS3 code so far:

    var loader: URLLoader = new URLLoader();

    loader.addEventListener (Event.COMPLETE, onLoaded);

    list.addEventListener (Event.CHANGE, itemChange);

    function itemChange(e:Event):void

    {

    your. Text = list.selectedItem.data;

    TB. Text = list.selectedItem.label;

    }

    var xml;

    function onLoaded(e:Event):void

    {

    XML = new XML (e.target.data);

    var it: XMLList = xml. Planter.Lauvtre;

    for (var i: uint = 0; i < il.length (); i ++)

    {

    list.addItem ({data: it.}) Farge.Text ([i]) + "\n"+ it.» Herdighet.Text ([i]) + "\n" + it. Hoyde.text ([i]),

    label: it. Botanisk_navn. Text() [i] + "\n"+ it.» Norsk_navn. Text() [i]});

    }

    }

    Loader.Load (new URLRequest ("lauvtre.xml"));

    Thank you!

    Rheus.

    I don't know what you're trying to do.  but, if you want to fill one combobox with the botanical names and when one is chosen, the other use of logins:

    var loader: URLLoader = new URLLoader();

    loader.addEventListener (Event.COMPLETE, onLoaded);

    list.addEventListener (Event.CHANGE, itemChange);

    function itemChange(e:Event):void {}

    var selectedObj:Object = a [list.selectedIndex]

    trace (selectedObj ['fan'], selectedObj ['Botanisk'], etc);

    }

    var xml;

    var a: Array = [];

    function onLoaded(e:Event):void {}

    XML = new XML (e.target.data);

    var it: XMLList = xml. Lauvtre;

    for (var i: uint = 0; i

    list.addItem({label:il[i].child('Botanisk_navn').toString()});)

    a [i] = {'Fan': it [i].child('Farge').toString (), 'Herdighet': it [i].child('Herdighet').toString (), "Hoyde": he [i].child('Hoyde').toString (), 'Botanisk':il[i].child('Botanisk_navn').toString(),'Norsk_navn':il[i].child('Norsk_navn').toString()};}

    }

  • PC can not read audio data from any media player

    computer laptop windows 7 my mother began to just expose some strange problems. She is unable to play any of his music on his pc using WMP12. the same files will also not play using iTunes, but I can cancel the iTunes issue for now because the problems are related. I was able to get the files to play on my PC in WMP12 across the network, so the files themselves are not at fault. work the system sounds in Windows, but when I say WMP to play a wav file, it errors out as well. I tried to reinstall the audio drivers, and run the troubleshooter of wmp and the resolution of the problems of audio playback, but nothing wrong was found. SFC has found no problem either. before resorting to more drastic measures (restore, reinstall, etc.). I well I ask here to see if I could get assistance.

    Seems rather strange, that my first thought is to check the volume, in windows 7, you can set the volume for different applications, like Chrome. I don't see anything else I'm afraid. You hear the music when played from YouTube? If so, it may be a problem in the settings for music apps, in general. Another idea would be to try to install K-Lite, to ensure that there are no problems with codecs.

    Except that I can not think what you could make, but restore to a time where you could play music.

  • problems after upgrading firefox. reset this is ugly. created the new profile, but can not recover data from old profile.

    I use firefox on a MacBook pro. Mac OS X version 10.7.5. There was an update of firefox on a day or 2 ago. Since this was done, I was getting 'syntax error' 5 times, each time that a page has been loaded. Some research has suggested that an application or a plug-in called "social fixer" might be the problem but I could not understand how to get rid of it so decided to try to reset Firefox. Minutes passed and a message was on the screen saying the old files of firefox have been been "cleaned" or something, but it seems to be 'stuck' because the progress bar was little jerky. Doesn't it usually doesn't. So I clicked on "Cancel". After that, I couldn't even firefox to start. Looks like my profile is unavailable or inaccessible. Following the instructions found on the support site, I created a new profile and I thought I copied the files from the previous firefox on the new profile, but when I run firefox, it's a blank slate. None of my bookmarks or passwords are there. It must be here somewhere, but I can't seem to understand.

    Looks like there was a problem with updating the profiles.ini file.

    You can try to remove the current profiles.ini file to force Firefox to create a new default profile where Firefox has not done that.
    You can check if there is a profile folder with a number of attached time stamp and in this case, you can set the location of a profile created in this folder.

    If you need to recover data from an older profile, always in the default location, or as a folder of old data of Firefox on the desktop then see:

  • Reading GPS data from a cRIO

    Hello world

    I use a module in series or with cRIO 9870 9014. I have need to acquire analog data with the GPS data and lang + long for each data point.

    I am able to get to the host vi gps data, but I am confused about the acquisition rate. I was curious and place a control on front panel to watch the gps in my RT vi data and I see a lot of spaces. (photos attached). I watched a lot of good examples on gps with the readers of visa, but since I'm on a cRIO with a TCP connection, I don't know how to process the data of succession on the controller.

    Can anyone help me please with ideas to use the module straight series.

    Thank you

    Tamanna

    Since it is a serial connection, you need to be constantly read the 9870 on the FPGA.  Even if your gps only updates once a second, that "update" has strings of unsigned 8 bit integers representing all of your characters - each read one of these U8s, seize only if you read at 1 Hz, will NOT correct data.

    So... Read on the FPGA continuous, faster better and passing in a FIFO to pass off to the host so that you can decipher your data. You may need to adjust timeouts on i/o reads.  Definitely take a look at the examples in the example for communication finder series with this module.

    And... as a diagnosis... you should be able to do this easily plug into the port series to your controller and use the controls VISA ON THE HOST RT - ethernet connection has nothing to do with it.

    For diagnosis, the indicators more the better. Let me know if you more specific issues.
