Read from String

Hi all

The question I have is probably very trivial, but I apparently I'm stuck with it. The task that I am doing is to transfer a 'string data' that I get from reading via RS232 port of a controller of movement (relative coordinates of the position of the engine), in a table, so I can use it following the curve of the path. The chain is as follows:

TPM: * TPM + 1274.36, + 0, + 0, + 56.149

and I want two of these four numbers in the data file, something like this + 1274.36, + 56.149, by rank

When I put 'write LVM' express VI and wired it "read rs232" to "signal in VI" me gives error that the data do not match. I therefore feel that the string must be changed somehow before it can be written in the data file.

Can someone help me with this problem please?

Thanks in advance

It's my VI:

You will need to use a function such as match on the palette of the string pattern.  Would be the model to look for the TPM secure: * party TPM assuming that is common on all lines of incoming data.  Then write the part after string matching in a text file.

Since you just want to write the data to a text file, do not use the file function measure Express.  That really does work well if you already have a data type of 'Signal' as those coming from other Express VI.  Just use functions open close text, write files, in the range of file IO instead.  Search for Finder example for some examples.

  • Readed hexadecimal string converted to a decimal number.

    Hello! I do a vi to check the hours of the lamp of my Sony projector. I send a hexadecimal command which is: A901 dignitaries 1301 0000 139 a senators. When the projector receives answer with 1901 1302 0031 339. 0031 corresponds to the data that I need to convert it to decimal because it tells me how many hours we used the lamp. How can I get this read-separated string to get only the third part of hexadecimal numbers converted to decimal? Thanks in advance!

    Hey rounded!

    As the data is in a format string, the hexadecimal number VI string should work well in this case.

    To enter only a single figure of this string to use in the hexadecimal number string VI, then I suggest using the string subset VI; Returns a specified segment of a string. By changing the offset of entry which determines which part of the string data is beginning to be analyzed from and changing the length to control the amount of characters to analyze, you will be able to enter the character that you want to convert.

    Once you have built your VI and compiled into an executable file and deployed on another machine, it essentially becomes a file read-only, which means that you will not be able to change the balance in this deployed application.

  • How to write constantly to analog output and read from analog inputs

    Hi all -

    I had a question about writing continuously to analog output reading simultaneously an analog input.

    It's my first time to post a message to the community, so please let me know if I made mistakes.

    I use Labview 2011 with a NEITHER-DAQ USB 6215.

    I'm looking to generate a waveform and write it continuously in an analog output. It is then connected to an entry on the acquisition of data, where I am trying to sample the analog signal. (I realize, there is a system of trivial, but I'm hoping to build on it once I have run).

    The task of reading from the analog input works fine, as I tested it in several other cases. I have a problem writing to the analog output.

    For this task, I tried to follow the "Gen Cont Wfm Clck Int' VI to generate the wave form and start the task. I then try to write to the output of the analog timed loop. However, it does not seem to transmit a signal and doesn't give me any errors.

    I have attached the VI but also a screenshot.

    Please let me know if anyone has any ideas. I would really appreciate the help!

    Thank you

    Peter Borgstrom

    We will review your tasks one at a time.  First of all, the task of generation/Analog output Waveform.  Generate you a waveform (I'm unsure of your VI if it is a fixed waveform or not) and send it to a defined output function to produce a waveform continuously, using N-channel and samples of N (where you set not these previously).  You should not put this inside has timed loop, as the DAQ hardware has its own clock - if you simply put it in a while loop (with a stop to break out of the loop), the loop will call the function for the first points of N, wait until all N have been taken out, then call it again to another N points (up to what you press Stop).

    Now, suppose that you have the output connected to a load voltage (say a decent resistance).  You can wire the input terminals of your A/D converter through the same load and set up a similar analog input loop, running in parallel (i.e. in its own independent of the OD loop, while loop).  You pourriez start together (with, say, a merged error since the initialization code line loops HAVE and AO become lines of error in "loops of sampling" described above), but you might want to delay loop (a little) the AI so that the OD has a chance to set the voltage before the bed.

    I hope this helps.

  • Spaces and tabs to scan from String

    Hi all.  I'm sure this question has been answered before, but I couldn't find exactly what I was looking for.

    I have problems with the scan string function.  My format string specifies the tabs (\t) as separators between several settings, but it also uses spaces.  So a string that contains spaces causes failure on the next parameter, because it expects a number, but sees instead the rest of the chain.

    Please see the attachment.

    If I replace spaces by a token (in this case #SPACE #), I can read the string and numbers correctly.  So, I have to re - replace the chips with spaces after reading it back.

    Therefore, I'm looking for is a way to specify the tab charater as a delimiter, but not the space character.

    Thanks for your help.

    I would like to use % [^ \t] in this case, that will read any character that is not a tab.
