Long data collection in the buffer using the PXI-6551

Hi all

I would try the following (or similar).

1 configure the PXI-6551 script that works continuously (or a large finite number of times).

2. for each execution, the script executes a finite number of SPI or I2C data reads.

3. the data is stored in a buffer memory embedded and quickly seized by software, there are no data overruns or collisions.

4. the software is able to close the task when a table properly (huge) size is filled.

Is this possible?  Only the service acquisition multi-record for PXI-6551.

Please advise as soon as POSSIBLE.

Thank you.

Hi all

It seems that I don't have a reliable advance trigger to ensure acquiring multi-record reliable job functions.  In my work of repetition of generation, an active event data (rising edge) is exported that once which initiates the acquisition.

So I redesign the task acquisition as a record acquisition only (but huge) task successfully.

My main goal was to reduce the time that takes to download large waveforms on the 6551, that has been accomplished by generating several times the same waveform.

Thanks to Jon of National Instruments, which has stuck around to help.

    If you have used a library template to send the documents for signature, you can export the values of individual transactions by going into the tab manage and then scroll down to the section template Library, single click on it and on the right side, click on the history tab and select ' export the data. It will download the CSV file with data of form field of all transactions made using the model of the library.

  • Scoring and data collection for the Simple Flash game using Actionscript 2

    Hello all-

    First of all, let me say that I am not very well or well informed when it comes to actionscript...

    I could really use some help with a problem I encountered.

    My company has developed a very simple type "Whack-a-Mole" game for a social media campaign.

    See here: http://www.hereforyoueverystep.com/social/game.html

    Our customer request now that we add a rating system so that we can offer a price for the best 3 scores.

    What I need, is to link the number of "hits" on a partition and allow the user to enter their e-mail address at the end of the game connected to the score they achieve.

    It was developed in Actionscript 2, because of a tutorial that was followed.

    If anyone can give me some advice or offer to edit my files directly, I would be very grateful.

    Thank you!

    Create a variable (for example, note), initialize it (to zero) and increment when a Mole is stubborn.

    Then, you create a database on the server that stores the best scores.  You must use the flash LoadVars class to update and extract high scores and you will need to use the script to write in your database server-side.

  • Calendar and the problems of data collection with the DAQ Assistant

    Hello NOR Developer area,

    I am a Novice of LabVIEW and have seen how helpful you all can be, and if I come to ask for your help.

    I'm having some trouble with a VI I built that specifies an input voltage, a SCB - 100 connected to a PCI-6031E and converts this tension in a temperature displayed on a waveform table. The goal is to give a constant reading of the temperature and display it in a chart for as long that the VI is running (and to reset the chart the next time the tracks of VI).

    The problems I've encountered currently are:

    -After a few minutes of the VI running, I get an error message 200279: tried to read samples that are no longer available. The requested sample was already available, but has since been replaced. (to the DAQ Assistant express VI).

    -I don't know how to change my chart so that the minimum value X is both during which the VI was launched and have the maximum X value increases with each iteration of the loop. Currently, I have the VI get the time system and contributing to the property node X scale. This worked for the graph of the voltage, but not for the temperature chart

    I appreciate those of you who took the time to read my post.

    What property node is talking?
    I do not understand that many different data types. How can I go on the treatment of all the data?

    (Did you mean I should wire 'blue' data for mathematical functions rather than using the node property tension?)

    Sincerely,

    In fact, one of the nodes property.  I mean specifically the tension property node.  But in reviewing, I noticed the other nodes in property for the chart.  Just set auto-scaling to the X scale and that should take care of two of the nodes property (right click on the graph, X scale-> AutoScale X Scale).  I also recommend placing your mathematical functions in a Subvi to make things easier to read.  Attached, that's what I think you're after.

    I hope that these small tweaks will speed things up enough to avoid your error.  If this isn't the case, then we should begin to look at the design of producer/consumer model or take readings at the same time.  It might also be worth looking away the DAQ Assistant and DAQmx real screws.  But one step at a time.

  • Programming on Board on the PXI-6132

    Hello

    This is my first post, so please be abstain.

    Asked me to develop a Labview Vi for the acquisition of data. I must acquire and a number of disintegrations exponential (as happens during the discharge of a capacitor through a resistor) averaged for calculating the decay constant. My boss has already bought a chassis PXI-1073 with a PXI-6132 to acquire the data. My question is this: since the sampling rate must use is very high, I want to minimize the amount of data transferred from the PXi system to the computer, with my system (windows 7, LV 2011, nor-DAQmx?), so it is possible to "say" the PXI-6132 to isolate the data belonging to the decomposition of exponantial on average several decays, then send the data to the host?

    Thanks in advance for your help

    Channel counter in the example I did you, is the meter, you use to generate the clock signal. Therefore a finished with 30 pulse pulse train if you want to acquire 30 samples.

    This channel can be configured as redeclenchables and control 'Source', you must select the PFI where the trigger signal is wired. It depends on how you did.

    The clock signal is routed internally, which means that you don't need all cabeling, simply select the right source for your route of entry of the AI (for example. Ctr0InternalOutput if you selected against 0).

    So external signals will only be ounces you want to measure with Amnesty International and the trigger for the clockgeneration (counter) signal.

    In MAX, you can do a right click on the device and see the layout of the pins on your device.

    Your OrgVDC have a stray or not network?  There is a known issue that there must be at least a valid network on the OrgVDC you want to manage.  This could break the data collection for other organizations, so if there is a 'test' organization, it would be better to go to the resources page of calculation under the company administrator and delete all these management resources.

    With a bit of work by someone who knows how to do such things, not Apple computers could read some files on the Mac if file sharing is configured on the network... devices non-Apple and... He knew the device passwords or administrator for Macs.

    Mac could also play the files on other Macs if file sharing has been implemented and the device password or admin was known.

    Hi MYR.

    If I understand what you're asking, you should try the DaqStream.AvailableSamplesPerChannel property:

    If you perform a task of counter entry in the buffer, then this property can be used to query the number of samples available in the input buffer that have not yet been read in the application memory.

    Please resolve.

    HIGH_VALUE datatype is LONG. You may not use for a long TIME in WHERE clause expressions. You need to loop through the partitions by selecting HIGH_VALUE and then comparing. Secondly, there is no need to select double to calculate expressions. For example:

    Select to_char (add_months (trunc (sysdate, 'MM'),-1), 'YYYYMM') | ' 00' in the double last_mnth_var;

    should be replaced by

    last_mnth_var: = to_char (add_months (trunc (sysdate, 'MM'),-1), 'YYYYMM') | ' 00'.

    and there is no need to add_months here:

    last_mnth_var: = to_char (trunc (sysdate, 'MM') - 1, "YYYYMM"). ' 00'.

    But the main question is simply ALTER TABLE MODIFY PARTITION COMPRESS allows compression but does not compress. You must issue ALTER TABLE MOVE PARTITION COMPRESS:
