• Cannot change the decimal sign in timestamp BUG

  
  

  I submitted a request for corrective measures to the LabVIEW Developer support this feature. The ID of the CAR is 4I0EE2BQ. That said, I don't have an estimated date for when the problem will be solved. You should check back periodically with our application engineers.

• Attempts to display unsigned numbers and signs in single chart

  Hi all

  I am trying to find a solution to a single graph between the display of a signed integer an integer not signed and switching.

  Basically, I have a U16 source that comes from a table.  Some of the table is signed, some is not signed.  I break up the table in separate 'channels' and then graphically display in a chart (a ' channel' at the same time).  For testing purposes, the table is just several meters ranging from 0 to 65535 over and over again for non signed, and simply by putting the source through a converter I16 me gives-32 768 to 32 768 for the signature.

  My problem is I want to be able to see unsigned and signed data on the same chart; If I know that a 'channel' is not signed, then a switch is a way, and if the 'channel' is signed then I press the switch.  I wonder how, if it's possible to 'move' between the unsigned source and the converted data to the converter I16.  I tried a box Structure with a switch, but the data sticks as U16.  I tried the Select function, but entries must be of the same type, which does not work either.

  The easy solution would be to have two graphs, but this seems to be a workaround hack rather than a solution to the problem.  If anyone could help, please let me know if there is a solution on how to do it in style with Labview!  Any questions, let me know.  I put a screenshot to describe what I'm trying.

  This is how...

  

• How to read the entire signed in the Modbus IO Server 16-bit register

  HI, I'm using Labview 2011. I like read 16 bit holding register to another PC using Modbus.But option is there only to read "registry of operating as 16-bit integers from 0 to 65 535".

   

  "But how to interpret as signed integers, as some registry values can have negative values". If the reading as unsigned integers, values is false. Is there a way to convert unsigned to signed integers integers.

  Ahmed Tafesh

  Yes, you can do the conversion... just be careful to not change its value or to complete something you need in the conversion process.

  Since the block diagram, range of functions-> programming-> Digital-> Conversion

  Try the I16 or the FXP. The I16 is a direct conversion, so you can't really control how it gets converted. The FXP you can right click and select properties to make the conversions.

  If all else fails, you can do the U16 to binary to FXP to I16. It may be the long way to get there, but it should work.

• Is it possible to determine the cod are signed without using mobile?

  Is there any tool or any procedure whether the cod are signed or not? Is it possible with the Simulator?

  Hello

  You can double-click the .cod your file in your project folder.

  The computer will tell you the status.  for example, 1. 2 "unsigned". "Signed" 3. "" Not necessary. "

• First HP: Partfrac gives crazy answers

  I am recently taken a first HP to replace my TI-Nspire CASE and in almost every way I used it so far, I think it is a much better device.  However, there is one thing that really frustrates me.  The frac command part even if I am sure that the answer is correct, that it is simply ridiculous to work with.

  I try to get partial fractions of (z)/((z-0.5)(z-0.8)) and the first gives me an answer that I can't easily type here since it is medium long.

  My TI gives a real simple (40 / (3 (5z-4)))-(10 / (3 (2z-1)))

  Is it possible to do the HP to put things in simpler terms?  I tried to simplify and it goes nothing.

  Hello on4now4,

  I am not a number first, but a hp 50g. I saw in your example, you use 0.5 or 0.8 numbers. The first and hp 50g operating system have a similar concept. If you type in numbers with the decimal sign calculators switch to another mode and then CASE (hp 50g will automatically use the way of reconciliation, the first maybe the home mode), where these functioning as partfrac do not work as expected. Try your example with fractions 1/2 instead of 0.5 and 4/5 instead of 0.8. This can work.

  Awesome!  It does not work!  A little annoying that I have to enter as a fraction, but I can live with this solution.

• ERROR: HDLCompiler:69

  Hello

  I'm trying to compile code for an FPGA on a 7965R FlexRIO. This works very well for the default clock frequency (40 MHz).

  I would use a higher rate of good, but in this case, a compilation error occurs:

  ERROR: HDLCompiler:69 - '\NIFPGA\jobs\IgEJ5Z6_rYTw6YC\Interface.vhd' line 172: is not declared.
  ERROR: HDLCompiler:69 - "\NIFPGA\jobs\IgEJ5Z6_rYTw6YC\Interface.vhd" line 173: is not declared.

  ERROR: HDLCompiler:69 - "\NIFPGA\jobs\IgEJ5Z6_rYTw6YC\Interface.vhd", line 175: is not declared.

  I searched the forums for this issue and it seems that people solved the problem by changing the decimal sign in Windows. It has not helped.

  Some claim, they have had to rebuild the project, which has not helped either.

  Any suggestions?

  I hope that I made my problem clear but do not hesitate to ask questions.

  I'm using LabVIEW 2011

  Thank you!

  OK, it's now the code compiled without errors. The trick is to define a different top-level clock in the FPGA - properties of target FPGA project.

  Sorry for wasting time in person!

• Cast of Type FPGA

  Hey, all!

  I'm transferring some run settings of a host to the target FPGA using DMA FIFOs.  I'm looking to possibly reduce the overheads of packaging my data a little more purposefully.  For example, two associates I32s being crammed into only one 64-bit and separate side FPGA.  However, when I split the data, the data becomes U32.  Now, I have no way to accurately perform any math on the numbers, as I lost the sign.  There is no way to type cast in a signed integer once on the FPGA target that I see.  Someone else has solved it, or am I relegated to just using two I32 DMA FIFOs?

  Dan M.

  If force you to unsigned to signed and the number of bits is the same, you basically get a deal to reinterpret. Which would allow you to retrieve your number, signed again.

• How to pass session managers to test the support?

  I tried the examples, but could not learn something useful.

  I have a DLL of LabWindows/CVI the following, and I am able to use functions (selection) the DLL in TestStand measures.

  int DLLEXPORT OpenSession (unsigned long * session, signed long * ErrorCode, char * ErrorMessage)
  {
   
  * session = fnThatReturnsInt(0,OPT1,1,1);

  return the 911;
  }

  int DLLEXPORT CloseSession (unsigned long, signed long Sessionhandle * ErrorCode, char * ErrorMessage)
  {

  deviceSessionCloserFn (Sessionhandle, 0);
   
  Return to 912;
  }

  The tester C works great. How can I tell TestStand store/use this session in Action follow these same DLL?

  Thank you very much!

  Hey ObiCaban,

  Is it possible to switch to the session "of reference" as a parameter in the parameters of module of TestStand?

  Kind regards

• Strange behavior with Scan function

  Hi, I see some weird behaviors with the scan function.  Here's a code (for Interactive execution) window which illustrates what I'm struggling with:

  #include 
  static double value;//    1234567890123456static char buffer[20] = "-  24.612 g    ?";
  static int scanneditems;
  static unsigned char sign, stable;
  static char unit[6];
  
  scanneditems = Scan(buffer, "%s>%c[u]%f%c[d]%s[w5y]%c[u]", &sign, &value, unit, &stable);
  

  The buffer I'm scanning has five parts.  The first character is a sign, the next 8 characters is a floating point number, then there is a space that just throw, then five characters is a string that describes the unit, and the last character is a question mark if the reading is unstable or a space otherwise.  The problem is with the last character.  When I run the above code, the value of the variable 'stable' is 32 (space), when I expect a 63 (question mark).  The other points seem to parse correctly, including the double value and the 'unit' char array that contains [g] [space] [space] [space] [space], which is exactly what I expect that it contains.

  It seems I'm missing something obvious, probably something to do with the way that the scan function manages the spaces, but I just can't understand what it is.  Thank you.

  I'm not sure about how Scan treats spaces, but if you check NumFmtdBytes () after the scan you see 12, which means that it has scanned only the 'g' (fill the rest of 'unit' with spaces according to the modifier there) and read the character immediately following the stability.

  This line correctly reads the entire string and returns bytes 16 analyses by the function, which is what is expected.

  scanneditems = Scan (buffer, "%s > %c [u] %f %c [d] %s [-w5t] [u] %c", & sign, & value, unit, & stable);

• How can I undergo so many?

  I have an Oracle table with the column "column number (20).
  I use the following code for the binding:

  OCIBindByName(stmt, &number,
  errhp, (text *) ":col_name", -1, (dvoid *) &number,
  (sword) sizeof(number), SQLT_INT, (dvoid *) 0, (ub2 *) 0,
  (ub2 *) 0, (ub4) 0, (ub4 *) 0, OCI_DEFAULT)

  But the data, written in the table, are incomplete.
  I tried SQLT_UIN but the results are the same.
  The variable number is declared as unsigned long

  If your value is truncated, it means that it cannot be held in a 32-bit integer value.
  Your column is declared as NUMBER (20) so it can contain values that exceed the capacity of a 32 bit integer, and so you should use 64-bit integers.
  BEAK is not supported yet (maybe one day lol) are binding 64bits whole C. You must use the OCINumber type for this.
  Here is an excerpt from a response I made in a previous post on the same topic:

  Vincent Rogier says:

  SQLT_INT or SQLT_UIN are limited to 32-bit integers.
  To use whole 64bits, type C is long long long, unsigned long.
  Binary_double using does not work because with very large values, there is a loss of data.
  The only way I found to manipualte whole 64bits correctly uses OCINumber.
  For example, to define a placeholder for output to get the data of a column of number (20), you must:

  * set using SQLT_VNU with size = sizeof (OCINumber)
  * extraction
  * then the buffer is an OCINumber
  * use OCINumberToInt() with the sizeof (long long) for the rsl_lenght parameter
  * Then you have a correct value

  You can also use good OCINumberSign() before calling OCINumberToInt() to see whether the value is signed or not, and then you go a long long unsigned or signed long long to OCINumberToInt()

• iteration signed integer and not a integer unsigned, why?

  I was wondering if there is a reason to keep the iteration of a loop to a 32-bit signed integer variable/indicator.

  He will never take a negative value... then why sign; unsigned could serve the purpose

  Bloop Shah wrote:

  but it wouldn't be better to introduce the NaN in full to assign a set bit just for a - 1?...

  who and where negative numbers are used?

  or is there something more than what satisfies my intelligence?

  Integers use every bit, which means that each combinations only bit is a real value. It must be this way to the full support of all the features of math. For example, if you take the difference between the two U32s tick counts, you get the correct time (as long as it is shorter than 2 ^ 32ms), even if the counter wrapped around between the two graduations.

  Because of the representation of the floating point (mantissa from the exponent, sign) numbers, we can define combinations unusual bit with a special meaning (NaN, - Inf + Inf, etc.). It is not possible for integers.

• Ethical signed always generates error unsigned on device

  Hello

  I built an application (BabyTracker) that publishes data to a device from rim over http to a url.  It works very well in the JDE and Simulator.  However, I get an error when I run the app on my device (even if I signed the app)...

  «Error at startup BabyTracker: Unsigned module 'BabyTracker' does not contain a class in com.rim (except com.rim.samples), net.rim, net.blackberry, java or jav»

  My development system consists of the following:

  * IBM PC under XP SP2

  * blackberry JDE 4.5.0.7

  * 8100-Vodafone-4, 5... Simulator 055 (uk)

  * Unit of Vodafone UK v4.5.0.55 (Platform 2.7.0.68) 8100

  The steps I am following are:

  1. create and test the app with 8100-Vodafone - 4.5... 055 Simulator (works fine)

  2 sign app by double clicking on the BabyTracker.cod file, by clicking on "Request".  The signature tool appears as shownin attached: sigtool.jpg.

  

  3. connect the device via USB

  4. run javaloader-u load c:\data\javadev\rim\babytracker\babytracker.cod... I enter the password, and the application appears on the device

  5. try to run the application and the following error: "error at startup BabyTracker: Unsigned module 'BabyTracker' does not contain a class in com.rim (except com.rim.samples), net.rim, net.blackberry, java or jav»

  Note: the JDE has not created a BabyTracker.csl file.  In reviewing this bbs, I noted that a missing file of csl is sometimes a problem.  I looked at the csl files that came with JDE application examples and noted that they contain one or both the following two lines:

  52424200 = RIM Blackberry Apps API
  52525400 = RIM API implementation

  then manually, I created the .csl file and added lines.  This has not solved the problem.

  Can someone advise me please know what steps I'm missing?

  Thank you very much

  The error indicates that one of your classes is set in a system package. Say the package statement in BabyTracker.java?

  The convention is to use your internet domain written back to ensure that they are unique. If you own mydomain.com statement should look like:

  package com.mydomain.babytracker;

  If you don't have a domain, you can use your name. Not really unique, but probably close enough for a phone application:

  package eanhernandez.babytracker;

  Cheers, Barak.
