Example VI "convert LPT I2C"?

• I2C + class motor from examples of robotic controller

  I try to combine (i.e. to use together in the same project) the motor controller class used in "Starter Kit 2.0 Custom FPGA" with I2C of "Communication I2C - sbRIO" in the examples of the Robotics module.

  I have already combined the FPGA code in a single FPGA VI and have tested the two individually.  When I go to use them together, I can't use the same FPGA VI reference because one is designed using a FPGA VI reference in dynamic mode (engines) and the other uses an FPGA VI reference that isn't in dynamic mode (I2C).

  So, what should I do?  I was going to try to convert the I2C in dynamic mode, but the only way I'd be able to do is to open the FPGA reference in each Subvi (since I can't bind to a type in the dynamic mode definition).  It also looks like trying to convert each other would be a nightmare because it would require to change the classes also (which is a mystery to me).

  P.S. I have sbRIO-9632 (Starter to be transferred to a large robot Kit)

  Nathan_B. . I met the same problem, when I mixed the two codes.

  And the only way I found to resolve this problem, configure the device "FPGA" in dynamic mode, then create a control and change of the Subvi in relation to the 'I2C Protocol', with this command (replace the input and output of the 'Sub - VI' - reference fpga). In this way, I realize the work programme. (see attachment).

• FPGA read/write eeprom I2C

  Someone at - it an example of LabVIEW for I2C communication to read/write an eeprom?

  I use sbRIO-9636 with FPGA.

  I already tried with the "Advanced I2C" example, but it works...

  Can someone help me?

  Another suggestion:

  You know about the VI package manager? There, you can install an application open source I2C & SPI API (worms. 3.0.0.22). It is an easy way to implement a system of Bus I2C on an FPGA target.

  In this way is a little bit smarter.

• Does not include how to start the DNG Converter to install Camera Raw for feature dehaze PS C6.

  I downloaded DNG Converter but I can't find the installation for PS C6 and Lightroom.  Adobe online instructions say starting with DNG Converter.

  The DNG Converter stands on its own and is used to treat the RAW images, for example to convert to DNG, which can then manipulate obsolete versions of ACR.

• VMware converter 5.5 failed with the error failed to partition the disk of destination

  I tried to convert the centos linux server physical to virtual. However, I received an error message at 1% as below,

  Error: Impossible to partition the disk of destination.

  FAILED: an error occurred during conversion: "CalculateGPTPartitionLocations failed!"

  
  

  Conversion of GPT partition is available vcenter converter 5.1 and higher, so the GPT partition on the source server will not be a problem.

  Tried several ways as the storage of data changing but still receive the same error message.

  Anyone encounter this before?

  Hello

  Unfortunately there is a bug with Linux P2V Converter when the destination drive is greater than 2 TB (is not whether TPG, it's size). Sorry for the inconvenience.

  The solution would be to reduce the volumes instead of destination and/or their distributed on multiple disks. Another solution would be to leave unchecked high-volume and clone them manually after the conversion.

  Another misfortune is that these workaround solutions are not possible in your case - the root volume occupies approximately 4.3 TB, and the two 'start-up' and '-' are needed to perform a conversion with the reconfiguration.

  The options I can think of are:

  -make a manual P2V, i.e. to create the destination (with partitions, logical volumes and base) computer created and formatted, clone the data (for example the converter uses tar via ssh) and manually configure the virtual machine. The final step is, fixing/etc/fstab, installation of GRUB and rebuild the initrd image

  -install new and copy data

  -Optionally divides the volume of root on the source machine if possible and then convert it. For example, to add a new drive temporarily and move some data so that all volumes become smaller than 2 TB.

• Why inDesign converts px mm in a very strange way?

  Hello

  My problem is when I'm creating a banner in inDesign (before you say anything, I do the banner on inDesign templates as we put the works prepared on a web platform that works only with .indd files and offers quick changes of files without the need of inDesign) and I set the size to 930 px to 180 px for example it converts mm which is good , but when a JPEG file is exported the size in pixels is autour 3000px x 750 px or something, why inDesign converts the units like that? If I use Photoshop to convert my units of its all fine.

  Any suggestions?

  InDesign is focused on printing. You can't really work in pixels, there there will be no idea what size of pixels. (Unlike Photoshop, which is a raster file and lives in the world of pixel).

  So, when you choose a size in pixels, InDesign converts just a real size.

  When you export to JPEG, clearly the design must be rasterised. The resolution has no relation to the resolution of all placed graphics, but is chosen on the export. The rules are very simple, for example, if you have a design, 10 x 10 inches and export at 300 dpi, you get 3000 x 3000 pixels. If you export the same design at 72 dpi you get 720 x 720 pixels.

• Convert number to timestamp

  Hello
  
  I have a number of data type column in a table that stores timestamps in format hhmiss
  
  For example

• Getting property of type 'Date' from a PDO data store

  It is therefore a question of both parties.  Part A: when I search for data in a data store, to find data by using the object Navigator returns the correct number of results, using the object. GetElementList does not work.  I'm looking in the data store for steps created between a certain date (using the iStartTime property).  It seems that they must return the same results.  Please see part A of my code pasted below.  Any suggestions?  Perhaps it is - that it is related to part B of my question.

  Part b: iStartTime property is the data type 30, or of type Date.  When I try to access the value of the property of iStartTime I got an error stating that ' the object does not support this property or method ".  Is there a special way to get the value of a property when the property is a date?

  Any suggestion would be appreciated!

  Sorry, I've replaced iStartTime by measurement_begin to make it work on my local database :-)

  The point is that the syntax of GetElementList is the following

  When converting a CDate to str it cause string locale-dependent.

  But the suggestion would be to use the

  Dim query: query = oMyDataStore.CreateQuery set

  instead of the query string. Because he avoid conversion errors. Be aware that even a double value to a string in Germany for example will convert a written decimal number while the stringquery expects at this point notation.

  Set MyElementList = oMyDataStore.GetElementList ("Action", "measurement_begin > =" & RTT (StartDate, "#YYYYMMDDhhnnss") & ") measurement_begin<=" &="">

  must provide correct results.

• Error 116 when a string of binary file reading

  I try to use the 'writing on a binary' and "binary file reading" pair of VI to write a string to a binary file and read it again.  The file is created successfully and a hex editor confirms that the file contains what is expected (a header + chain).  However, when I try to read the string back once again, I received an error 116: "LabVIEW: Unflatten or stream of bytes read operation failed due to corrupted, unexpected or truncated data.»  A quirk I found though, is that if I put "endianness" to "Big-Endian, network order", the error disappears when I use "native, welcome the order" (my original setting) or "little-endian" error occurs.  Did I miss something in the documentation indicating that you can use big endian order when writing of strings, I do something wrong, or is this a bug in Labview?  Because the program that it will be used for is to write large networks, in addition to channels, I would like to be able to stick to the 'native' setting for speed purposes and must not mix "endianness".

  I have attached a VI of example that illustrates this problem.

  I'm using Labview 8.5 on Windows XP SP2.

  Thank you

  Kevin

  Hello

  Please contact National Instruments!  I checked the behavior that you have met and agree that it is a bug, it has been reported to R & D (CAR # 130314) for further investigation.  As you have already understood possible workaround is to use the Big-Endian parameter.  Also, I am enclosing another example that converts the string to a binary array before writing to the file, and then converts to a string according to the playback of the file.  Please let me know if you have any questions after looking at this example though and I'll be happy to help you!  Thank you very much for the comments!

• Modbus communication with a piezoelectric dynamometer

  Hello..!

  I am a new user of LV and I try to communicate with a piezoelectric dynamometer in modbus RS232.

  After you install NI Modbus Library, I created a master VI with labview 8.6 using these libraries and I can get communication with scale, these values are added in the registry U32Bit 1 and it's good, if I press a load cell, I can see the values exceed. (from 0 to 65535). Now, I want to show on the front the weight in KG, as the decimal separator, for a proper interpretation of the value for my client, so I added a block table to unbundle that I convert a value with I32Bit (-32768 a 32768) with a flag, but I don't see not all values...

  I guess I did something wrong (conversion), I read a few KB, but I do not see a solution...

  Can someone give me a link or information to show me an example to convert this value... ?

  Thanks in advance for any help to...

  Configuration of master VI:

  Read now register

  Address starting 2012 (query to get the net value of the load cell)

  Quantity 1

  Slave address: 1

  RTU

  9600

  3 com

  parity none

  Can you post some examples of bytes you receive from the Modbus read and you expect that these values are?  It's probably just a matter of the right of casting, or the number endianism, or operation of scale that must be done.

• I got negatives on a CD. The instructions say to "run the Photo on the CD Viewer '.» How can I do this?

  I got the negatives on a CD instead of local printing. The instructions that came with the CD says: 1) Insert the CD into your computer [what I did];

  (2) run "photo Viewer for Windows: on the CD." Use the photo viewer to see photos & save them to your computer.

  If J tips do not help, download and install IrfanView (it's free).  Start IrfanView, click file > open, navigate to your CD-ROM drive, and then select the first file.  Once the file is open, you can use the left/right arrows in the menu bar of IrfanView to come and go through your negatives.

  You will see that IrfanView is a very powerful and versatile image viewing application.  Among other things, you can display many different types of image files, conversion between types (for example, to convert a BMP to JPG file) and resize the image (useful for emailing) files.

  Although you could save the files you open and view them by clicking file > save on each of them, it is easier to save all the files at once:

  • Put the CD in the drive
  • Open my computer
  • Double-click the icon for your CD drive
  • Click Edit > select all
  • In the right pane, click "copy the selected files.
  • In the context menu, navigate to the location where you want to save the files (probably in my pictures - you will need to click on the + sign next to My Documents to see)
  • Click the copy button

• I have no other choice than to install Win7 on FAT32 partition temporarily. How can he do?

  I have no other choice than to install Win7 on FAT32 partition temporarily. How can he do?

  Original title: on FAT32 Win7

  There is no way you can install Win 7 on FAT32 FS. Windows vista and win 7 support NTFS only. Win 7 and vista support Fat32 to read discs not for OS install.
  In windows disk management, you get only option FAT32 if the size of the disk is less than 32 GB. probably by design that MS has done.
  You can use the third-party partitioning as partition magic tools for example to convert the partition to FAT32 if you have more than 32 GB of partition
  If you convert win 7 partition FAT32 your windows os may not work.
