record data continuously using PDM

• Trouble when using the FPGA to record data on PDM

  Hello world

  I encounter something strange with the use of FPGAS to save data to the disk. I use 4 channels and allows saving data PDM. I use 4 different graphs to observe each channel and no bad thing. But when I check the data stored in PDM, they are not saved in the order that they are supposed to be. Each column in the PDM should represent 1 signla of a channel, but the result shows that the data seems to fill a single column, then another. I do not understand how it becomes like this. I have attached a few photos for your information.

  The data of the FIFO.read must be 1 d table, right? So when it passes through the form 'table' in my VI, it should become a 2D of the 4 column table. Each column represents the data for each channel. I don't see any problem with this Vi. Why PDM data are not saved in the right direction?

  Thank you

  In my opinion, that you simply return your dimension sizes.  The number of rows should be 500 and your number of columns must be 4.

• How to record data using a while loop?

  Hello

  I created a .vi I try to use to record several channels of data. I have implemented the user must be able to record data until the "STOP" button is pressed, then the data is saved in a spreadsheet file.

  Question No. 1: How to allow the user to store an indefinite amount of data?

  If you run the .vi as is, you will see that you are only able to collect 100 points, and registration takes place during Ms. I want to collect about 5 minutes worth of data and have a sampling frequency of 1 kHz.                 Any suggestions?

  Question 2: How can I change the worksheet file extension? Let's say I want than to save it as a .csv file?

  Thanks in advance for any pointers or suggestions!

  I have not looked at your code, but only based on your description I would implement a producer/consumer to save your data.  You must acquire your data in a loop (the producer) and send to your loop of logging (the consumer) using a queue.  Yes, you must save the data, then that is acquired.  In this way, you do not have to worry about storage who knows how much data in RAM.  It's just the disk as soon as he can.

  You can save the file with whatever the desired extension.  If you want it to be a CSV file, then do the extension a .csv.

• Problem to stop the task of continuous using API C DAQMx data acquisition

  I'm doing the acquisition of data in the PCIe-6536 continuously using DAQMx C API. But whenever I try to erase the task and put end to my application, program stops and it is not completed by the Task Manager and task killer applications. Can someone help me with this?

  Hi John,.

  Thank you for your concerns. the example attached also created the same problem. Then I run the test of the device to the MAX and it failed. Then I realized that there is something wrong with the installation. I simply uninstalled the card and installed on the other PCI-e slot. This time, self test has been successful and so did my request.

  So my problem has been resolved

  Again thank you for your quick response.

• Record data in the report for later use

  I have several names to the report I need to combine data from multiple files of the same type with different codes. Not all the names have the same codes. I want to communicate the data on a single line. Is there a way to save date for use later in the report?

  For example:

  Name Code Start Date Code Date Code promotion transfer Date

  Sue	SD	15/01/2000	TD	15/01/2005
  Mitch	SD	15/01/2004
  Sam	SD	15/01/2003

  I think that I now have a better idea of what you're trying to accomplish.

  You don't need a subreport for the dates of each person on the same line. It is best to do this in your query, for example:

  Select table_name. Username, dtFafsa.FafsaDate, dtLetterSent.LetterSentDate, dtLetterReceived.LetterReceivedDate
  the outer join left table_name
  (select userID, FafsaDate from table_name as table_name_fafsa where appchk_cod = 'FF') as dtFafsa on table_name.userID = dtFafsa.userID
  left outer join
  (select userID, LetterSentDate from table_name as table_name_LetterSent where appchk_cod = 'AS') as dtLetterSent on table_name.userID = dtLetterSent.userID
  left outer join
  (select userID, LetterReceivedDate from table_name as table_name_LetterReceived where appchk_cod = 'AR') as dtLetterReceived on table_name.userID = dtLetterReceived.userID

  It is obviously not checked the syntax, but it illustrates the concept.

  Each underlying table returns the date of each code. You'll need a table derived for each code you want to make account.

• Data recovery using Microsoft Money Standard bought in New Zealand

  I use Microsoft Money Standard bought in New Zealand.

  As a result of a malfunction of the hard drive, I installed a new and recovered all my data files.
  I reinstalled Microsoft Money, but Money files will not open.
  A message informs you that the file cannot be located or is read-only, I don't have the permission to open or it is write protected. None of this is true then I suspect it has something to do with Microsoft withdraws this product.
  I can see there are no version sunset for my version, so how I can I recover my data for use in Microsoft Money or importing to another product I need of course to buy at one time?

  Yay! Success.

  It's hotfix QFE, whatever they are, that became a problem when Microsoft has ceased to produce and support money.
  Users of the United States had a "Sunset Version" to allow them to continue to use the program, but international users have been left in the cold.
  Finally, Microsoft provided a download to help users with the UK or International English. Why they did not consider their international users from the very beginning, God alone knows that!

  For users of the International English Version of Money 2005 - published July 29, 2011

  I have downloaded and run the NASB and my Money file open immediately. Great!
  Now, I just need to look at what it takes to pass when I decide it is time to move from Microsoft Money.

• How can I use the USRP to record a signal using its two RX ports simultaneously?

  Hello.

  I am trying to record a signal using two antenna cone. The reason that I need two antenna to cover the bandwidth (DC - 6 GHz). a single antenna covers DC - 300 MHz and the other covers 300 MHz to 6 GHz. so I need to use two RX port of USRP at the same time to record the signal. I have two questions:

  1. is this all USRP market capable of covering this frequency range?

  2. is it possible to use the two RX port at the same time to the signals of the records I described? If this is not the case, how can do?

  P.S. I have two NI2920 USRPs and two USRPs N210 in my lab.

  Thanks in advance for your time.

  Sam.

  Hi Sam,

  To answer your first question, the USRPs you can reach the bandwidth you want. There is not a USRP, to my knowledge, that can reach this range in a single device.

  Also note that you can only use RX convened for two different ports at the same time using LabVIEW and the pilot of the USRP. If you want to use the two lines of RX, you will need to run a session with a single line, close the session and then start a different session for your second RX line.

  Hello

   
   
  1. who is the operating system installed on your computer?
  2. What is the exact error message that you receive?
  3. who is your Internet service provider?  Have you tried to contact them about this?
   
   
  Follow the steps mentioned below and check if that helps.
   
  Method 1: You can check if the router is configured for WPA and WPA2 connection:
  a. If the router is configured for WPA and the configuration of your wireless network on your computer must be configured the same way. That is to say, WPA.
  (b) if the router is configured for WPA2, then the configuration of your wireless network on your computer must be configured the same way. That is to say, WPA2.
   
   
   
   
  Method 2: You can manually disable authentication IEEE 802. 1 x. Subsequently, re - enable authentication IEEE 802. 1 x and see if the problem still occurs.
   
  See: If you use a NETGEAR wireless router, you can follow this link:

• Access blackBerry Smartphones to backup data without using a phone smart blackberry. How does this work?

  I had a Blackberry 9700 and I made a back-up via Blackberry Protect App. My Blackberry is stolen and I want to transfer all data (approx. 600 phone numbers) from the back-up to my PC or to my Samsung Galaxy SII that I can borrow temporarily from a friend. Bottom-line: I need access to my back-up data without using a Blackberry device. How does this work?
  

  Hey Sourbag,

  Welcome to the community of BlackBerry Support Forums.

  You will need a BlackBerry to access these backup information. There is no way around it in BlackBerry Desktop Software.
