• PCI-6110 continuous data

  I am trying to take data continuously from 4 channels maximum 5Msamples per second and writes at the same time as the data on the drive using the TDMS writer.   I use daqmx LabVIEW tools to read and write data.  I get failry good flow, but it is not completely continuous.

  1 is it possible in Labview?

  2. is it possible with NIScope?  NIScope is at all related to labview?

  Thank you

  Ben.

  I'm not an expert DAQmx, but it is a fairly common use case covered by the API. You can configure DAQmx so that when the data are collected, it is written as efficiently on the disk. You can do it for a continuous data stream. You can find an example of this here (and more examples using the LabVIEW example Locator: Help-> find examples...):

  \examples\DAQmx\Analog Input\Voltage - Input.vi continues

  This VI uses the data at the level, so you will want to choose not adjusted I16 data for the type of output to the maximum speed.

  Alternatively, you can use a producer/consumer architecture, acquire data in a loop and it continuously to the PDM in another. It is essentially this as the example above, but much easier and more quickly, because it involves fewer copies of data.

  Good luck!

• Excerpts from continuous data acquisition

  Hello

  I want to make an acquisition of continuous data with a NEITHER-6133 @ 1ms per channel. The data must be stored on hard disk. At the same time, I want to take excerpts from acquisition to calculate different values. The acquisition of the extract must be triggert by an external digital trigger.  Are there examples, which combine continuous data collection and collection excerpts?

  Thank you very much.

  Best regards

  NOR-6133

  Thanks to the support of NOR-Germany, I found a solution for me:

  1.) continuous trigger switch

  Connect 2) the trigger for the signal to a digital i/o

  3.) synchronize AI and DIO

  Excerpt 4.) the samples needed by the search within the digital waveform pattern

  Result:

  The example shows 4 IA channels Cup (tested on Win7, NI PCI-6115, 4 channels each 5. MECH / s) and calculation on extracts from each channel signal triggered parts.

  

• HOW TO READ DATA SERIES WITH SYNCHRONIZATION

  I have a question about my application for the acquisition of data in series. In my application, I use visa read to acquire data series sent by an inertial measurement unit. When I first put the sensor, it sends data in the following one time format:

  1:0 x 8011 header followed 1 data word for Adler, 1 data word (each 16-bit word data).

  and the sensor then starts sending the data in the following format:

  2:0x7FFF header followed 1 data word for checksum, 9 data word (each 16-bit word data).

  (Note: checksum is defined as a 2s - complement of the sum of 16 bits of the rest of the entire message)

  In my application, to simplify the problem, I use a wait function to ensure that the initial data header 1 tag is sent. Then I start reading using VISA Read 20 bytes (header 2 more words of associated data are 20 bytes), as I'm mainly interested in the data header 2 tag words.

  However, when I do this, the data that I get do not begin by 7FFF character and, accordingly, my 20-byte data cannot be parsed correctly. My question is how can I do the "VISA read" block read the serial port when data are preceded by '7FFF '.  Once I have solve this part, my strategy will be assembled data read 20 bytes (including the header of 4 bytes) and analyzed accordingly.

  Another question, I wonder if you can tell me how to use the given checksum it is defined as "a s 2 - complement of the sum of 16 bits of the rest of the entire message". Note the data that contains the header 1 tag is 1 post.

  I would appreciate if you have responded to my request.

  Thank you!

• How say continuous data 2D?

  Hi, I have problem with my block diagram. I plan to display data (from temperature probe NICrNi) of several channels and memorizing the data in csv and tiara permanently file. Now the problem is how to say continuous data 2D (double data types)? because the result of the measurement are very unstable... I try using the function means PtByPt VI but she need to double entry of data types... Are so there is another way to describe the data? for example I need an average of data for every 20 samples.

  
  

• How to count the continuous dates in oracle 11g

  Hello
  
  I need to count the continuous more than 9 days between given dates below is my example
  
  Are my data like this
  MAY 1, 2013
  MAY 2, 2013
  MAY 3, 2013
  MAY 4, 2013
  MAY 5, 2013
  6 MAY 2013
  MAY 7, 2013
  MAY 8, 2013
  MAY 9, 2013
  MAY 10, 2013
  
  Now I want the number of days between these continuous days of more than 9 days now, I will get the result for the above data is 10 days
  If any date is not in the list then days would not result if it is less, then are equal to 9 days
  Here is an example of another
  MAY 1, 2013
  MAY 2, 2013
  MAY 3, 2013
  MAY 4, 2013
  MAY 5, 2013
  6 MAY 2013
  MAY 7, 2013
  MAY 8, 2013
  MAY 10, 2013
  11 MAY 2013
  
  number of days here is 10 but may 9, 2013 is away at the moment, the county should not show as 10 because continuous date (May 9, 2013) is absent, that's what I need, please suggest the solution.

• DAQ USB 6363 - generate digital data series through the single DIO line

  Hello

  I'm new with Labview, currently, I bought NI DAQ USB 6363 for generating control signals and signals analog accquire. I would like to send digital data series through one of the digital IOs with throughput of 30 kbps. Please see the attachment for the data frame. Could someone comment the feasibility of this? Y at - it codes for the example that I can refer to? Most of the examples I've looked at so far deals to generate several line instead of 1 single line. How can I achieve this?

  Thank you

  Hey diem.

  After looking on your code, I understand what you were trying to do. Here's how I'd do. Usually we do not write code to clients, but you peaked my curiosity of! I hope this helps. Good luck!

• missing data series for port operation in

  Hello.

  My unit is transfer 51 asynchronous data bytes in frames (each image to 80ms) on six different channels (ch1, ch2, ch3, ch4 rate 19200 baud and other two ch5, ch6 baud rate 115200) and these data series of six diff is received by my system and it should be checked for any error byte... (as I'm new to labview I programmed a long vi) in which use visa read and process the received data. But now, my real problem starts... until some time that my system will be receive data without no loss but aftr some time (say 15 minutes approximately) data loss starts from the track being baud rate of 115 200 and later other channels begin to do the same... But my system is supposed to run for 4hours for a trial of endurance of a plane... If the data loss is very less in number its OK but 3 of 4 frames then starts missing... it's like losing 75% of data... I enclose a wink of my code... It's just for a single port (in a while loop) I took... Imagine I; did the same thing to rest the port in a single while loop... Please guide me where ive that has gone wrong, or is this something to with time delay... pls help me

  the thing is always my application system needs will grow more, so I have to rectify this himself in the beginning

• I32 flipping index iteration continuous data acquisition

  I'm doing some continuous data streaming with Labview FPGA and periodically generate a trigger signal

  the timestamp after a number fixed iterations.

  The strategy I would try was to review the iteration index in the timed loop and whenever he tipped a fixed number I would generate a trigger of the FPGA.

  I tried to find out what happens when you get to 0x7FFFFFFF samples on the register of I32 and apparently

  the index does not roll... It just remains to count max once reached it.

  Is there a way to derail the index on a timed loop? Otherwise I wil just add another

  U32 variable and increment it each cycle and let it roll on.

  the iteration count does not roll.  Therefore at this historic moment, but just use a registry node, local or feedback shift instead.

• How to get data that are created the or before the last Wednesday

  Hi, can someone please tell me how to write a query to retrieve the data that are created the or before last Wednesday.

  Thanks in advance...

  Hello

  Here's one way:

  WHERE created_date< next_day="" (="" trunc="" (sysdate="" )="" -="">

  , "THURSDAY".

  )

  "Before Thursday' means the same as 'the or before Wednesday '.

  This assumes that NLS_DATE_LANGUAGE is English.  If you are not sure what is NLS_DATE_LANGUAGE, you can do this:

  WHERE created_date< next_day="" (="" trunc="" (sysdate="" )="" -="">

  , TO_CHAR (DATE ' 2014-03-06' - or any Thursday)

  , 'DAY '.

  )

  )

  There is nothing magical about March 6, 2014; will do any Thursday.  To_char will return the translation of 'Thursday' in all that is the current NLS_DATE_LANGIUAGE, and NEXT_DAY can use this value.
