characters of VISA not in ascii

I use ARM Cortex microcontroller. I send you the numbers in the display of the laboratory via usb port.

In this case, the strings from VISA Read are not ascii, but I can convert them to unsigned int with the help of the uint premitive string.

The numbers must be sent are continuous and they consist of u8, u16 and also float values.

The problem here is the conversion. only these value that are defined as u8 appear correctly.

How to convert the appropriate values.

For example if the value is greater than 255 but whole, I should be able to read and view.

If the value is float I should be able to view the number of good float.

I also tried with scan chain premitive, also the number premitive string. They can only read ascii and convert, but the characters I'm conversion are not ascii.

Like the characters I get boxes and a value of 0, they are empty.

To convert a number in ASCII in my microcontroller might also be possible, but the requirement here is with a view to laboratory. Microcontroller currently has the huge load of programs.

I'd be happy if someone help me forge in this.

Thanks in advance.

Hi fhs.

'300' is stored in two bytes with LSB First: 44 + 1 * 256 = 300. As mentioned previously, you can use "join the numbers' to achieve the desired result.

-'1' is perhaps stored in just one byte, but that is not clear in your photo.

'1.23' is probably stored in 4 bytes (or 8?), but is not also clear your photo...

To show more data. And switch the output string for 'view hex', before taking the 'grass '!

  • convert integers in equivalent characters in string - character of ASCII code

    I got out of my data and information of the associated string to an array of strings, and then to a spreadsheet file.

    I want to do this by converting an identical string of characters (integers and other numbers).

    I tried Type font with a constant string as the input of type but it DOES NOT WORK.  Instead, I get the ASCII character whose numeric designation corresponds to the integer, for example integer '50' become 'P' capital.

    I want all over '50' string '50 '.

    Please advise, and no, I don't want to make the berries of the clusters.

    I found my answer, but only after the search for 'Number' rather than 'Integer' conversion conversions.

    In the range of programming - number of string - string/number of Conversion - decimal string functions:

    'Converts number to a string of decimal digits less than width characters wide or more if necessary. If the number is floating point, it is rounded up to a 64-bit integer before the conversion. »

    Is this a known problem with NI-VISA on Red Hat Linux?  Or that this indicates that there is a problem in our NI VISA on Red Hat Linux installation?

    Gordon,

    I found a customer who had the same problem, it was his solution:

    I traced the problem of how our system administrator has installed VISA 4.3.
    Due to security requirements, the default umask for root is set to
    disable users ' access to the files installed by the root. Therefore, when the VISA
    has been installed by the system administrator, the part of directories have been
    unreadable by users, and when the VISA (viStatusDesc) tried to gain access to the
    error text files, it's been blocked. Once the repertoires of action have been made
    accessible to users, the error text returned correctly by
    viStatusDesc.

    Check again so that your account has the appropriate access to all VISA files.

  • Possible GPIB communication through interactive control of Visa, not with Labview

    Hello

    I have a communication problem with Labview with GPIB instruments (with functions of visa).

    I get:

    "Error 1073807298 occurred at the VISA opening

    Possible reasons:

    "VISA: (Hex 0xBFFF003E) failed to perform operation due to i/o error."

    However, it works with an interactive control visa and this is where I am confused!

    Here is my setup:

    -Labview 2011 assessment

    -VISA 5.1.2

    KUSB - 488B with the associated drivers (adapter USB to GPIB of Keithley)

    Because I can speak with my instruments in visaic, I guess the installation of drivers for the Keithley interface is ok.

    Trace IO NOR I see beeing of commands passed through Labview to VISA so that they "see" between them.

    I found a thread where someone had the same problem and its solution was downgrade to Labview 8.5.1, which is not possible for me.

    http://forums.NI.com/T5/instrument-control-GPIB-serial/Keithley-2700-driver-problems/TD-p/1474212/PA...

    You have an idea to solve this problem?

    Kind regards

    Baptist

    Here's a follow-up on this issue.

    I tried with Labview 32-bit on main machine: it works.

    The pleasure is that I have to use Labview 64-bit.

    So the ultimate solution is now to run a client and a server of visa on the machine: Labview 32 bit can directly access my resources GPIB, Labview 64-bit must go through the closure of the network.

  • Resource of TCP/IP of VISA not presented to the MAX

  • When I type some characters often do not appear but if I wait for awhile and tap them again once they appear.

    This happens in all programs that I can type, (e-mail, WP). Sometimes I can type the characters if I come back, space or both using the arrow key and then forward and try again.

    Laura V:

    Thanks for your help. It was a very frustrating experience, not being is not in a position to have all the I type characters appear. I did a full scan and who was clean. I was not able to boot mode safe then I deleted all the programs that I installed for several months, but the problem of many characters not appearing not when I typed persistent. I was about to bite the bullet and to restore an image of my C drive from a hard drive external when I decided, just for completeness, to test the keyboard. I unplugged my wireless Logitech keyboard and plugged an old keyboard. Eureka! Typing all appeared OK. What a relief. I think that the rf in my wireless keyboard transmitter was at fault and that it was not send all the characters I typed. I should have checked the keyboard first, but it was only 3.5 years old and I couldn't believe that it went wrong so little time. All's well that ends well. Thanks again.

    Key.KEY_END should be used, I suppose... I agree with BBDeveloper, there is no constant static like CONTROL_END or CONTROL_HOME

  • Buffer series VISA not containing data not received all

    Hello

    I get the competition of the transmitttet of the LGRTest.txt file for my port com3 (9600n81) every second.

    Using 'VISA on event Wait function' I was supossed to read the summary after detection of a character of 0xA.

    But I get only at random parts of the 486bytes transmittet.

    In earlier versions of my code, he did receive the prize. But I discovered that it was old data stored in the buffer.

    Then I added "VISA Flush function" before wait as the chariot of the end and then I got the first problem I designed.

    Concerning

    Morten Skov

    The event to wait for the VISA is pending for ANY character to receive.  So if you check the number of bytes in the port when half of the message has been sent, you will only read half of the message.

    If you actually use the stop character, don't bother with the VISA events.  Just a reading VISA with the number of bytes to read the value something rediculously high.  Read full when it detects the stop character.

  • Link with characters not ASCII

    I'm trying to insert a link in the Pages v 5.6.2

    The link to insert is: https://es.wikipedia.org/wiki/Generaci on_y

    That is a perfectly valid link to a Wikipedia article (in Spanish), but it's URL contains a character not ascii (o)

    When entered at the prompt of link Pages supposed is a bad URL and let the link by default (www.apple.com) or the previously entered if you change a link.

    Is this expected behavior? This will prevent from many URL of wikipedia, not only Spanish, but many languages and also all the other pages that contains characters that are not ASCII, which are much like RESILIENCY now considers perfectly valid http://www.w3.org/International/articles/idn-and-iri/.

    I don't know where to post this, so I leave it here. We hope to see this fix.

    This is solved in the editor page links using substitution of encoding for the character of o as shown below. B3 C3 is the sequence of UTF-8 for this letter, and you discover that by launching the character palette (Edit menu: emoticons and symbols) and looking for the letter o. Latin lowercase letter o acute accent will be among the related characters, and when you click on this character, it will be apparent the UTF8 designation.
