Some parts of the chain has lost communication with the Arduino.

Everything by contacting arduino, the chain that I receive from the arduino is buffered, but it is not completely read by LabVIEW

and change the data to trace some information is lost. Someone knows how to fix this?

Information may be useful:

Arduino mega

Baud rate: 19200

Delay in the Arduino loop: 10 ms

The string is composed of 3 integers values concatenated like this:

gh123ab123cd123ef

I m attaching the Vi.

Thx a lot!

Paulo

Is your waiting time in fact 0 milliseconds?  It is not very long wait for a message to come.

Each message ends with a line as a termination character newline character?  You have the default stop character.  If Yes, then you're better to read a large number of bytes and let the end of termination character read, rather than using "bytes to the Port.  So now that you read, not all bytes have arrived yet, then you're bytes to the port will be less that you really want and you'll have the wind reading an incomplete message.

    Your photo has been damaged due to a hardware malfunction. It could be the card of the camera, card reader/cable USB/USB port, hard drive or memory.

    You will need to run some diagnostic tests to determine the bad component. Try to import photos for different material aid. If possible, bring on a completely different computer.

  • You want to read binary files in some parts of the 500th row in the 5 000th row.

    I have files of 200 MB of 1000561 lines binary data and 32 columns when I read the file and sequentially conspire full memory of the generated message.

    Now, I want to read the file in pieces as the 500th row 5,000th row with all the columns and it draw in the graph.

    I tried to develop logic using functions file advanced set file position and the binary file reading block, but still not get the sollution.

    Please, help me to solve this problem.

    Thanks in advance...

    Hi ospl,.

    To read a specific part of the binary, I suggest to set the file position where you want to read the data and specify how many blocks you must read binary file for reading binary file.VI

    for example, if you write table 2D binary file, and then mention you data type this 2D chart and make your account (5000-500). Then together, you produce position. If you have 32 DBL data type and column then it is 256 to the second row and 256 * 500 for line 501th. Use this number as input into your position.vi file get.

    I hope you find you way through this.

  • some parts of the page is missing

    OfficeJet 7310, Windows 7 64

    Just noticed a few days ago that my printer is not printing parts of the page.  The colors are very well and very good print photos.  The missing lines or parts of a line would be black or color and are missing.  Drivers and software are up-to-date and nothing of fact to make it.  Makes no sense but what is happening.  Any ideas?

    It turns out that the problem isn't with the Chrome browser.  Have referred the matter to them.  Thank you.  I'm glad that the problem isn't my printer.  Impossible to find one that prints as well.

  • Some parts of the text color change?

    How can I take a text and select different parts of the text to change the color for the selected party?

    Thank you.

    Depends on. You could do it with a gradient, which would allow you to keep the direct text, but you will need to do a bit of hoop jump to do. Not too much, but your question made me think to your probably not yet to the level of comfort with the Illustrator requires this hoop jump.

    So instead, you'll need transform the text to outlines and then cut it into pieces and pieces of color. When you do this however, you should know that the text is no longer text, it is art and therefore cannot be changed.

    Select the text

    Put contours by typing the command-shift-O (Ctrl-shift-O on PC)

    Select the knife tool in Control Panel tool (not the slice tool, which looks like an exacto blade, but the knife tool that looks like a steak knife. It is hidden under the Eraser tool)

    Drag the tool knife through your letters, making sure to start and stop outside the letters if you cut all the way through.

    Use the direct Selection tool, select the songs you want to color and choose the appropriate color swatch.

    Ta-Da

    Hope that helps,

  • Some parts of the page is cut when it goes to the next page.

    A few notes:

    -Place the lines of code out of the cfdocument tag cfparam.

    -remove the link cfdocument tag. The link tag can only appear in the head section of the page.

    -remove the cfoutput tag. There is apparently no need;

    -remove the long comment lines . If you need break the document into sections, use the cfdocumentsection tag. A previous thread contains an example of the use of section tags and cfdocumentitem and cfdocumentsection feed page.

  • How can I change some parts of the audio?

    I want to change the volume of certain parts of my audio. lower and raise the different parts of my audio, but not completely remove audio or spitting it upward. Someone who can help me?

    Hello Zach,

    Hearing has 2 modes of editing: waveform and multitrack.  Waveform is a single file editor, generally used to modify and overwrite the original file or convert them to a new file when the installation is complete.  Multitrack is a nondestructive environment where present you several files on a timeline.

    To adjust the level of volume in wave form, you can select the region that you want to set up and use the screen volume control button to change the amplitude.

    You can also use the effect of Gain envelope for waveform of keyframe volume changes, you want to do.  Add points on the line and adjust them upward or down, get an overview and once satisfied, click on apply in the window of the effect:

    If you add an item to a multitrack Session, you can use the clip or track volume in the same envelopes to automate volume changes.  The difference is that this does NOT replace the original file.  Once satisfied, when you create a mix makes a new audio in the file with the changes made.  You can also return to the session and make changes later, a new mix of rendering as necessary.

    Hope that helps!
