• How to find valid cases in the truth table?

  Hello

  I am using a truth table to select the next case in my state machine. The number of possible cases is 256 with a set of 8 input of Boolean values. The following is a generic example.

  Obviously, I don't need the conditions of passage, but how to weed them out of the table?

  0          1          2          3          4          5          6          7          8          9          10        11        12        13        14            15in house?            F          T          F          T          F          T          F          T          F          T          F          T          F          T          F            Tpassed test?       F          F          T          T          F          F          T          T          F          F          T          T          F          F          T            Tscrapped?          F          F          F          F          T          T          T          T          F          F          F          F          T          T          T            T in inventory?      F          F          F          F          F          F          F          F          T          T          T          T          T          T          T            T

  I often do.  Take each of your eight Boolean and consolidate them in a table, convert the table number and select your case on that based on the number.  Thus, if the first fifth suite and boolean (from above) are true, you have 25 case (10011000 = 25).  You can have a case manage multiple values, separate them with a comma in the selector.  It will make you famous.

  

  I do the same thing, but the value of the radix of the binary display case.

• BlackBerry JDE App - generation of a truth table

  Hello

  I'm working on a blackberry app that is supposed to derive a Boolean function of a truth table, with the function being in its simplest form.

  I have a problem with the display of the truth table, I need to show the truth table and take as input to the function, how can I do this?

  If anyone has any ideas please answer as soon as possible.

  Thank you

• jQuery in the table selector

  Hi people of jQuery.

  A technique for information on other elements of the line has been mentioned a few times (example)

    var row = $x_UpTill(t, 'TR');
    var index = $('input[name="f10"]', row)[0];
    $s('P55_INDEX',$(index).val());
  

  It took my more long as it should be, but I found the documentation on the current setting of the 'line' represents a limited part of the DOM - in this case, TR us

  http://API.jQuery.com/jQuery/#jQuery-selector-context

  But I would like to know what the [0]? I'm unable to track documentation relating to this, and the code seems to work without it.

  I'm guessing that this could mean that if there are multiple matches for the selector, it uses the first match. Maybe that's performance and safety?

  See you soon

  It's really stupid. There is always an input with the f10 name element in a given line, so it would be unwise to get the first one. Even then, if you want to get the first and work with jQuery and want to continue working with jQuery objects, then using . eq() | jQuery API Documentation or pseudo-selector of : eq() selector | jQuery API Documentation are much better choices.

  In this case, the execution [0] is the same as .get (0) and basically returns the dom instead of a jQuery object element. . get() | jQuery API Documentation It's stupid, in that regard, that, on the next line, it is simply transformed into a jQuery object again...

  I would also like to point out that, instead of using $x_UpTill, I prefer to use . closest() | jQuery API Documentation or maybe even better . parents() | jQuery API Documentation

  with t as the starting of the line element:

  $( 'P55_INDEX', $(t).closest('tr').find('input[name=f10]').val() );
  

• OR TRUTH TABLE.

  NULL in the table 3 logic (which is what SQL has implemented), is considered to be UNKNOWN. It is either TRUE or FALSE, but is not known (yet?).

  In your case 2 and 3, that's not really important what NULL turns out to be (TRUE or FALSE): FALSE and... whatever..., will always be FALSE. TRUE or... anything... always has the value TRUE.

  Now cases 1 and 4 you do not know: it is unknown what the result of the expression will be, depends on NULL proves to be...

  Lex (my co-author, see profile) wrote an entire annex on the logic of a value of 3. You can read that.

• "Structure of case: no case for some values of selector" error

  Hi all

  I'm new to LabVIEW and get an error that I can't get rid of. My code is made up of a state machine with 5 different States. I don't know if this is a common mistake or if I need to provide more information. Please let me know and please help.

  Best regards

  L.E.

  This is explained in the help of LabVIEW: http://zone.ni.com/reference/en-XX/help/371361H-01/lvhowto/specify_default_case/

  You drive the structure of the case of an enum. If you connect an enum, you must provide a case for each enum value or specify a case as in the case of failure to perform if no case matches the value of the enumeration.

  -Or-

  You drive the structure in the event of a string or numeric and do not have a case specified as the default case if no case matches the value in the alphanumeric string.

• AND / OR truth in SQL table

  Solomon Yakobson says:
  Well, NULL means value is unknown.

  Distinguishing on this specific statement (get all semantic on you ;-)) - NULL is not a value in itself.) That's why we can use mathematical operators on it, because there is no value to operate on. And that's what means NULL. No unknown value, but no value.

  Think about a column in Oracle as having two possible States. A value or no value.

  NULL is therefore a variable or a column "+ State +" descriptor and not some kind of value that is assigned to it.

• Insert row into table 2D retaining the previous values

  Amendment of data entered in a 2D array and also displayed a table. When the time rolls 3 columns of data are held and then created line. Problem is the line moves downwards, but the previous data is not stored. I tried using shift register, but that only auto markings lines table to fill as the iteration of the loop. Looks like a basic really simple problem but going round in circles on this one there...

  In this case, the function 'Replace table subset' is what is needed to replace the last values in line with the current values of the user interface.

  On the evolution of the time, an addition occurs.

  An update of the VI is attached.

• generate the subset of the decimal table to an array of Boolean

  I have a decimal table 1 2 3 4 5 6, and I have a boolean with the same table size 0 1 0 1 1 0.

  How can I retrieve the subset of the decimal table of the corresponding "1" position of the table of Boolean (in this case 5 4 2)?

  The value of the Boolean table are editable (casting either 1 00100), so the size of the array decimal subset is not fixed (1, 4).

  (I assume you mean digital Board. "Décimal" is just a specification of formatting and irrelevant for this)

  Try something like the following (the FALSE case has just wired table in the whole unchanged):

  

  (In case you're dealing with huge paintings, a few performance modifications should be made so that everything goes more in place.)

• Set the size of fixed table

  Hello. I am developing a VI to a FPGA target and I'm trying to make sure who is using the VI can specify the size of an array of input when they instantiate (such as by the presence of an entry to the VI who said "maximum table size" or something). So far, it seems that the only way to do something like this is to go into the VI himself and manually set the size of table for each entry in the table for the VI (open the VI, do a right-click on each input array, select 'Set the size Dimension', choose 'fixed', set number of items). I would like to have a point where I can set the size of all tables at once (as in my case, they are all the same size) and let the person using the VI set it to the right size for which application they use it for (to be clear, let's say I have two uses for this VI and in one case (, I have a table of entry of size 100 and other use of size 1000, I would like to be able to put these in some way rather than do it through the dialog box). Thank you.

  It's a little more work, but it could be a case of good use for a memory block on the FPGA.  Make it bigger you wait, you need, and then store the actual number of items somewhere.  This will allow you to vary the amount of data without consuming large amounts of FPGA resources on an oversized table.

• What SQL script to use to configure the default TestStand tables?

  Hello

  I'm setting up a small test application and want to record the results of the test to a SQL Server database. Page in preparation for the implementation of logging database mentions the scripts I use to set my database. In my case, I found 3 table creation scripts:

  • SQL Server create insert generic result Tables.sql
  • SQL Server create Recordset result generic Tables.sql
  • SQL Server Create Tables.sql stored Proc result

  What are the differences between them, and which one should I use?

  Thank you!

  In the options dialog of database--> go to the patterns tab and click on each of the options (generic recordset, insert generics, etc.). In the comments section, you will find the difference.

  You can use one of them but to ensure that any script that you ran the DB tables same option is selected in the DB options.

  I hope this helps.

• tables that the decision-making process

  Hello

  I have a list of tables that must be used as input for decision making. attached are the VI and the input file. What is the high_data > 10, it must perform the square root which is under the real condition. When the high_data is less than 10, it should return zero which is false conditional. I tried to use the Chooser of the case, but it seems table cannot be used for the selection of cases. Can someone help me with this. Thank you

  First of all, you have the race condition because of the flagrant overuse of a local variable. Most likely, the local variable is read before the terminal of the table gets valid data. Remove the local variable, and use a wire directly. Do not forget, LabVIEW not Executive up and down or left to right. The order of execution is entirely determined by single dataflow. If you have multiple processor cores (and you probably have), things can even Executive in parallel.

  Second, have you tried simply to encapsulate an autoindexing FOR lop around the structure of matter? Then clean the proof of the scythe, which needs a scalar instead of an array, etc... There are also solutions without loop, but let us in to the essential.

• Case of Structure / while loop problems

  Hello

  I am trying to write a code that draws a random number whenever a key is pressed.  The chart must be a random number on the y axis and the number of times that the button is pressed on the x-axis.  I want to draw the last twenty random numbers.  I use a while loop and a box structure.  If the button is pressed, the case structure incruments the number of times where the button is pressed and generates a random number.  I'm using shift registers to track the last twenty numbers generated.  When the key not, registers to shift to day values incorrectly.  My code is associated with this issue.

  I know that the last value of the shift registers of wiring to the structure of the case will change the table across the last value when the button is not pressed.  I know what causes the problem, but I don't know how to fix it.  I would appreciate it if you have a look and give me some tips.

  Thanks in advance.

  Your problem is that the loop runs continuously and your values in the shift register are replaced when you do nothing.

  There are a few ways around this.  It would be simpler to use a Structure of the event.  Another option is to simply store your table in the shiftregister.  Use Rotate 1-d Array and replace a subset of table to update your chart.  It is a little more robust and easier to use than using the history of the shift register.

  But the absolute simplest, based only on what you told us, just use a graphic instead of a graph.  A graph keeps a history.  The length of the default history is 1024 samples, then you want to reduce that to 20.  Then you just wire your random number right in the chart, and everything is done for you.

  

• place memory safe table

  Hello.

  I work with an array of "big", and I would like to know if I'm just doing.

  I am given concatenation (SGL) on my program and with him, build a larger painting each iteration of the loop. I calculated that I need a table with about 200000 points. If I'm right, this isn't good at worked with a shift register, because if the table is larger each iteration Labview urechi new table every time. So, what I do is initialize an array with 200000 points NaN and after he fill it with a constant =. Its this right?

  Thank you

  Hey Navarro,

  initialization of a table prior to the size correct (or necessary) is recommended.

  Case 'period': delete this table later by replacing it with a blank matrix constant is nonsense.

  Case 'save': adding new items to your table is a nonsense - why you initialize it before?

  Use InitArray with ReplaceArrayElements!
