How do I send out a certain number of pulses

I am using the E-Series DAQ board, and in my programing I have three stages, I need to send out a certain number of pulse depending on the stage selected. For example if stage one is selected 30 pulses will be sent out and thats it. The pulses will be used to move a stepper motor. The stepper motor is a linear stepper so the pulses will be used to move the shaft 1 inch or 3 inches, depending on the stage selected.

It sounds like you want to generate a "Finite Pulse Train". Depending on which programming language you intend to implement this with (LabVIEW, LabWindows/CVI, Measurement Studio for Visual Basic or C++), we probably already have an example written. From our website at www.ni.com simply search for Finite Pulse Train. You will want to only use examples that have been written for the DAQ-STC chip, which our E-Series DAQ devices leverage.
The finite pulse train examples will show you how to output a finite pulse, of say 30 pulses, as well as configure the frequency and duty cycle.

  • How can I send out pending agreements for signature en masse on a scheduled basis?

    I'm using EchoSign's Salesforce integration, and I'm trying to create a scheduled batch that will send out a large number of agreements for signature.  EchoSign has some exposed global methods that I'd hoped will help facilitate this, namely AgreementTemplateService.load, which generates an agreement based on an agreement template ID, and EchoSignAPIService.sendDocument, which sends out an agreement that it is provided.  Also, using the background action field on Agreement, it is possible to update an Agreement to 'Send', triggering its send-out.
    I can do all this through code anonymously, or via a custom page at the click of a button, but to do it without user interaction is proving difficult.  Regardless of whether I try to do it via trigger or scheduled batch, the above-mentioned methods fail out in different ways that essentially amount to the same problem (trying to call a future method from a batch, or a callout from a trigger); I've reproduced the error messages here (these are stamped onto the agreement record and displayed when the record is viewed):
    System.CalloutException: Callout from triggers are currently not supported
    System.AsyncException: Future method cannot be called from a future
    You have uncommitted work pending. Please commit or rollback before calling out
    It seems the above methods are intended for use in a custom page, rather than in some scheduled, non-interactive use-case.  Is there any workaround for this, or support for sending out agreements at a scheduled time, rather than at the click of a button?  Thanks!

    I'm not an Adoby guy, hence you may ignore my reply, but Adobe Dynamic Link is obviously not just one way ticket and in most cases works just fine.
    You have already been explained by J-MS and tclark513 how to properly use it and which pitfalls may occur.
    So as to apply an effect onto a whole sequence or a group of clips you need to either nest them in PrPro or pre-compose them in AE. Then just apply an effect (or several ones) onto that composition.
    So, if you nest clips in PrPro, select your nested sequence in the timeline, right-click and choose 'Replace with After Effects Composition'. Done! Your dynamically linked AE composition is in the right place in your timeline and in your Project panel as well. If you can not treat it as an ordinary footage, there are obviously some mistakes in your workflow. 
    If you didn't nest your sequence or a group of clips in PrPro before replacing them with AE composition, you may easily do it within AE. Just select all the layers in AE composition and choose Layer -> Pre-compose... (Ctrl/Cmd+Shift+C) Done! Switch back to your Master comp and apply your desired effect(s) 
    You may loose some effects or/and transitions while travelling from PrPro to AE via Adobe Dynamic Link, whereas you don't while travelling back
    (If you start building your AE composition from scratch right in AE and then need to import it into PrPro, DO NOT export one as PrPro project out of AE, but rather choose Adobe Dynamic Link -> Import After Effects Composition... within PrPro)
    P.S. And yes, submit a feature-request so that Adobe will convert 'Transparent Video' into fully functional 'Adjustment Layer'.

  • How can I find out what port number my DB is using

    How would one find out what port number a database is using? Is there a SQL command that will allow us to do this?
    Thanks,
    oracle_newbie

    newbie
    Oracle databse assigns a dynamic port number for each established session. Usually, the common port is 1521 which is defined in you tnsnames.ora, however, this is used for requesting a dynamic port. Dynamic ports are within a ragne of 1000+. That's why it is hard to tell which port you are using at a certain time. You should have a network monitoring tool to check this accurately.

  • How can I find out the apn number of the battery without having it?

    I dont have the battery of my iphone 5 anymore but how can i find out the apn number of the battery? I would like to change it but i need to know the apn number to choose the right battery.

    Apple does not provide any user-serviceable parts (other than accessories or sometimes a SIM card tray).
    Therefore, there are no legitimate iPhone batteries available for sale anywhere.
    Anything you find will either be salvaged, counterfeit, or stolen.

    How do I send out an email, so that I can recieve confirmation that email was delivered?

    If you are using Apple Mail, it does not support read receipts. Even if it did, most people will ignore such requests, so at best, it'd be a hit and miss situation.

  • How can apple send out an os update that renders an important function of the software/hardware to not work? They knowingly have sent out this new os update for iPad which makes airplay nonfunctining! I need this for my business!

    How can apple send out an os update that renders an important function of the software/hardware to not work? They knowingly have sent out this new os update for iPad which makes airplay nonfunctining! I need this for my business!  I could understand if they didn't know, but it is all over the Internet! When I went in to have it revert back to os6 (which worked fine!) I was actually asked if I had done any research before I installed the upgrade! As if this is the consumer's fault for being dumb enough to fall for the upgrade!

    That is not what I have discovered, nor what others have discovered, nor what I was told when I went the Genius Bar.  I cannot remotely mirror to my MacBook Pro and it only started the day after I installed the upgrade.  We tested it with an iPad that had not been upgraded, no problem.
