Cast of Type FPGA

Similar Questions

• FPGA Interface Cast question

  I play with a VST 5644 and model VST streaming.  On the FPGA VI, I added the code, then added an indicator of the face before of the FPGA VI and compiled.  Executes the FPGA VI in interactive execution mode, the indicator works well.  Side host, however, I can't access the new indicator with read/write control.

  Coming out of the open FPGA VI reference I can see the indicator on the wire, but in the Dynamic Cast of Interface FPGA function is have rooted out the refnum somehow.  If I connect to control read/write directly to the output of the function of open reference I can access the indicator very well.

  No idea what I am doing wrong?

  Thank you.

  You re-configured your FPGA VI reference with the new bitfile interface?  The cast of dynamic interface defines the lead as all methods and indicators according to the type of wire connected.  You can right click on the constant of type and select "Configure the FPGA VI... of reference".  In the pop up window that follows, select "import of bitfile...". "and select the new bitfile you've built.

  You must update the fpga reference type in the "Device Session.ctl" type def as well.  This is the type that you will be able to access throughout the project.

  

• Unflatten string or Type Cast?

  Hello.

  I send you an array of unsigned integer 8 bit with size 19203 since a TCP server in a c for a TCP client program in LabVIEW. I managed to receive the data, as shown in the image below. The first byte, which is sent by the c program is the header. The second and the third byte represent the size of the array, which is actually 160 x 120. Then the rest of 19200 bytes are the actual values for the table.

  

  My client TCP code looks like this:

  

  This problem occurs when I am replacing the cast of Type with the Unflatten to the string function and adding a dimension to two tables. The first two values in the table (120 and 160) must inform the Unflatten to the string of the size of the array function, but I don't get all the data of the table indicator.  Is there a way to create a 160 x 120 size chart from data in 8-bit uint 2d?.

  Orlando,

  Your client with the table 1 d code gets the data, but not in the format 2D, right? If so, use Array reshape. It also can automatically adapt to any size of 2D array where the first two elements of the 1 d array contains the dimensions of the 2D table.  I put the code outside the loop just because there was space on the comic it. It can be moved inside if you receive multiple messages.

• Please add support for channels DMA between RT/FPGA for custom types

  It is a request than a question at OR. Please find a way to provide support for custom types when data transfer between RT/FPGA. Even an ability to mount a type complex in a bit array and proceed with a redesign to the custom side type FPGA would be acceptable. Break my configuration in primitive data is completely unrealistic. So, I consume large amounts of FPGA resources passing data through the method of the façade. THX.

  There is an existing idea for this. Please Kudo it if you do not want to see this!

• An array of type cast to the cluster

  Is there a real difference between 'table of cluster' function, and simply type casting to a cluster?  The image below shows a simple example.  Apart from providing the names of each element of the cluster, type cast function automatically sets the size of cluster, which is a nice feature when you work with a typedef.  I really wonder if there is any downside to type casting when elements of array and cluster are the same type of data.

  Thanks in advance.

  

  Type casting man knows where I live, so my opinion is biased.  When I have to do such a conversion, which is hardly ever, but does not match ever, so I'm going with the Type Cast.  You hit the bigger points, meaningful labels and ease to spend six to seven to eleven elements with Type FED.  When I do this conversion it is usually because I have to do a magic of property whose tables do not permit (all components need to share properties with the exception of value).  Creating a table of function control Cluster is say a Clusterflop, according to the Type casting, exactly what I'm looking for.  In addition, table in the Cluster service performs a code obfuscation, is always maintained at 9 elements, and otherwise must disappear, or at least that:

  First of all, ask yourself if you really should do this, if the answer is Yes, then I say Cast of Type.

• Type erasure and relationship of cast.

  By shaving part of the erasure of the type of the document java tutorial (effects of Type erasure) and methods of bridge, I saw the code example below.

  public class {Node < T >

  public T data;

  public Node (data T) {this.data = data ;}

  {} public void setData (data T)

  System.out.println ("node. SetData");

  This.Data = data;

  }

  }

  SerializableAttribute public class extends < all > node MyNode {}

  public MyNode(Integer data) {super (data) ;}}

  {} public void setData (full data)

  System.out.println ("MyNode.SetData");

  super.setData (data);

  }

  }

  And follows the code below:

  MN MyNode = new MyNode (5);

  Node n = minutes; A gross type - compiler generates a warning uncontrolled

  n.setData ("Hello");

  Integer x = mn.data; Causes a ClassCastException thrown.

  The problem is that in the document tutorial he said, after the erase process of type above code like this changes.

  MN MyNode = new MyNode (5);

  Node n = min (monnoeud); A gross type - compiler generates a warning uncontrolled

  n.setData ("Hello");

  Integer x = (String) mn.data; Causes a ClassCastException thrown.

  Suddenly two typecast appears. I do not understand it. These two typecast appear in line 2 and line 4 does not appear in the class if file I open them with javap - c.

  If you open the class with javap file there is no type of plasters as above, except a single type conversion is present who tries to cast mn.data object type for the integer variable x.

  Also the class MyNode is not even a generic. Could someone please tell me why these (monnoeud) and casts (String) comes after the type erasure process, or the reason why it appears at all.

  Code changes is the equivalent that you might have written in your source code for the compiler that creates the same byte code.

  The casts of types are there to explain what object you get from the right side, so the ITI becoms apparent why this code throws a class cast exception Finally.

  But she inherits from the generic class Node and fixing his entire generic type.

  I am to convert the Microsoft Oracle for Oracle ODP.NET provider of my projects

  * Error *.

  Cannot be cast to type 'Oracle.DataAccess.Types.OracleDecimal' object type 'System.IConvertible '. Could not store < 145982 > in the RECEIPTID column. Type is Int64.

  This error is poped up when my stored Proc has a return parameter. The return is a numeric data type in Oracle. I had no problem when using Oracle Provider from Microsoft.

  Initially, I had my command setting insert the value

• Cluster for the FPGA reference constraint

  I have a cluster of clusters.  One of the internal piles went 25-29 items, but I forgot to update several of my Subvi reflect.  I remember before when I did, I got a broken line not executable VI, but now the result is a constraint.  You can really force a cluster with multiple items to a cluster with fewer items?  My outdoor group consists of some FPGA with clusters of register references.

  Hi Adams,

  FPGA reference is the special data of type "FPGA dynamic reference", which includes a cluster of records, elements, and associated with the referenced FPGA personality FIFO dynamically. Dynamic data types do not follow the same rules of coercion expected of them a defined data type statically to follow. The dynamic nature of reference FPGA son allow wire any FPGA reference in the entry of an order of read/write, regardless of whether the control of read/write was created explicility for the FPGA reference. This makes it much more practical FPGA programming.

  This means no timetable? The embedded clock's 40 MHz. It runs with this clock? Beacause 7833 compilations for the pci or pcie 7842 report displays the maximum clock time.

  Hello

  "none" means simply from what I can understand, that there is no violation of timing. The source of synchronization that will be used is (as you have already suspected it) on-board 40 MHz clock.

  As to why you don't get a mention of the MiteClk and the ReliableClk in summary, I think that it is due the 7833 and the 7842 relying on FPGA Virtex-II and Virtex-5, while the 7820 uses the Kintex-7 family. Depending on what type FPGA using different estimates regarding the use of the device and synchronization are not always available.

  As I said, as long as you don't get not an error of timing and your compilation is completed successfully, you should be fine.

  Kind regards

• Analyze the VISA reference name

  I have a multi channel test setup that uses a serial port for each channel. So, I named the VISA aliases for channels 1 - DUT DUT-8. I have a coaxial switch that routes a signal from the current to a freq counter INSTRUMENT so that I can measure the frequency. The switch has eight positions who use an enum POS0, POS1... POS8. I need to translate the serial port selected to the correct pole on the switch so I made the attached VI. The problem is that it works very well when its open but is not when it is closed. What can I do possible box this function with a closed vi?

  Try using 'Cast from Type' to convert the VISA refnum into a string, rather than the Text.Text property.

• Unpack the cluster data channels

  Hi all

  I tried for this research, it seems quite common, but I don't know that I used the right set of words:

  I receive data from a device in the packages. Each sachet contains several images, each image contains two subframes and each sub-frame contains several data channels. In my vi, the package is a cluster, executives are clusters and the subframes are clusters, all the typedef' ed.

  What I want to do, is to take the big initial cluster and divide the data into a set of tables, one per channel data, without generating spaghetti.

  The function "decimate the table" would work great to do the job, but alas, it only works on the berries, no groups, and it seems that my group cannot be converted to tables.

  Is there something that I am missing? I have attached a photo of high level... Note that I'm not an artist. "N" and "m" values are fixed, so there is no variability

  By "append" do you mean "build the table? ' You can use "Cluster of Array" instead?

  Also note that if you have a cluster where the latter are the same, regardless of how many nested groups there, then you can Cast from Type to an array of this type of final element. For example, if all data real of your cluster is single precision floats, you can the Type Cast to an array of SGL.

  If you can upload a screenshot or your code saved to an earlier version, I will try to provide more specific help.

• How to divide numbers (U32 to U8)

  Hello

  How to cut a number of byte values (U8)? I found the 'number of Split' - thing in labview. What should I use twice to U32? (first 32-> 2 x U16 and U16-> 2xU8).

  Or is it also a more rapid/more elegant way to do it?

  Thanks for help

  You can simply use the Cast of Type function to convert an array of U8.
