How to use labview to drive a New Focus Picomotor sinusoidally

Hello,
I am currently trying to use Labview to control a NewFocus Picomotor (Model# 8302)using the inteligent driver model 8753:
http://www.newfocus.com/products/?navid=3&theView=modelDetail&productLineId=6&productGroupId=195&mod...
http://www.newfocus.com/index.cfm?navId=97 (Using MCL with Labview)
Ideally I would like to modify a preexisting driver to drive the motor sinusoidally in the 30-70 Hz range with control over the amplitude. At this point, I am completely daunted by the complexity of the example files and have no clue where to start. Any assistance with this matter is GREATLY appreciated.
Best Regards,
BRox

BRox,
I had a look at the examples and obviously all it does is to communicate to the drive through RS232 with a proprietary protocol. With the documentation in the block diagram and the documentation of the protocol it shouldn't be too hard to understand what's going on, but on the other side NewFocus has obviously missed a chance to provide a high level and easy to use API for their product...
I can't dive too deeply into the features of this drive, but before you spend too much time on understanding their command language, you should check with NewFocus, if it is possible at all to meet your requirements with their hardware. The main reason why I doubt that is the slow communication speed provided by RS232. The only way to reach a sinusoidal motion profile of 30 to 70 Hz with this type of communication is running the complete trajectory generation and interpolation onboard. If you have planned to generate the motion profile in LabVIEW and send setpoint commands to the drive this will probably not work.
If the drive provides another command input (e. g. an analog +/- 10 V input for torque or velocity command signals), we can talk about alternative approaches.

Labview for New Focus picomotor driver 8732

I am trying to interface with a New Focus picomotor driver model # 8732 using LabVIEW. Any help would be greatly appreciated.
Thank you

Hi,
Check out our Instrument Driver Network for drivers that work well with LabVIEW. If your New Focus Picomotor driver is not there, I would suggest you contact New Focus and see if they have a driver that works with LabVIEW. If the driver is a regular dll, you can call functions from that dll by using the call function library node. More help on that node can be found here.
I hope this helps,

How to use the dvd drive...?

Hi Guys,
Just bought my new 15" 2.53 Mhz Duo Core MacBook Pro a month ago but until now I haven't figured out how to use the DVD drive. Well I can't seem to find where it is actually... Does all MacBook Pro has dvd drive? Coz when I check back apple's website and look for the same macbook pro specification like my one, it has a dvd drive included so I thought my macbook has it for sure but can't or don't know how to use it... This is my first time to have an apple that's why...
Hoping for your help..
Thanks,
Danny

Hi there Danny.
I believe you are looking for the location of the DVD drive... right?
If you are looking at your computer while it is open, it should be on the right hand side... "under" the keyboard. There is a slit that allows the DVD to be inserted into the computer. I think if you start to insert a DVD in there (shiney side down) part way, it will suck it into the computer.
(note: I'm not exactly sure, because I use a 7 year old iBook that has a pop-out DVD tray... but I think it will suck it in for you)

How to use the "identify" feature in new 6.3.1 airport utility?

how to use the "identify" feature in new 6.3.1 airport utility?
so you can find the basestations in larger networks?

There is a workaround, which is to use Airport Utility 5.6.
I can confirm that 5.6 will run on 10.8.4 Mountain Lion, it will recognize the new 2013 Airport Extreme Base Station (A1521) running firmware 7.7.1, and it will give you access to view the device's Log & Statistics, DHCP Clients, and Profiles.
Four caveats:
1) The easiest way to install it is to download the app itself, not an installer or through the App Store. There is a page here where you can download the app: http://coreyjmahler.com/2013/03/08/airport-utility-5-6-on-os-x-v10-8-mountain-li on/ This way, you still have both versions, Airport Utility 6.x.x and 5.6.
2) When you launch 5.6, you'll get a message saying a newer version is available and asking if you want to update. Click Cancel to proceed into the utility.
3) When you click the Manual Setup button in 5.6, you'll get a warning dialog that "This version of AirPort Utility doesn't support this AirPort wireless device and might improperly configure the device if you continue to use it. Check www.apple.com/support/airport for the latest version of AirPort Utility." You can click Continue to get into the utility without issue.
4) You should probably only use 5.6 to view the additional status details. I have not tried to modify and save any AEBS settings using 5.6. There are other discussions here in the forums indicating that attempting to save settings via 5.6 that are no longer available in 6.3.1 will not actually save the settings to the AEBS even if both utilities indicate that the settings are changed. See https://discussions.apple.com/message/22677993#22677993
So, even though you can't use it to modify settings no longer available in Airport Utility 6.3.1, using Airport Utility 5.6 to view DHCP clients, Logs and Statistics is very useful for troubleshooting network issues.
PS - There are two ways to get to the DHCP Clients list, neither of which is obvious The first is to go to the Airport pane -> Summary tab and click on the "Wireless Clients:" label in the Summary display. All of the labels from "Wireless Mode:" down on the Summary display operate as links to view/edit the corresponding info/settings, which is also not obvious at first glance. Also not obvious, clicking on "Wireless Clients:" actually brings up a new pane with three tabs: Logs, Wireless Clients, and DHCP Clients. You can also get to the same pane by going to the Advanced pane and clicking on the Logs and Statistics button.
I hope this is helpful information. Took me a while to find out how to do this.

How to use my itunes with a new pc

how to use my itunes with a new pc?

These are two possible approaches that will normally work to move an existing library to a new computer.
Method 1
Backup the library with this User Tip.
Deauthorize the old computer if you no longer want to access protected content on it.
Restore the backup to your new computer using the same tool used to back it up.
Keep your backup up-to-date in future.
Method 2
Connect the two computers to the same network. Share your <User's Music> folder from the old computer and copy the entire iTunes library folder into the <User's Music> folder on the new one. Again, deauthorize the old computer if no longer required.
Both methods should give the new computer a working clone of the library that was on the old one. As far as iTunes is concerned this is still the "home" library for your devices so you shouldn't have any issues with iTunes wanting to erase and reload.
I'd recommend method 1 since it establishes an ongoing backup for your library.
If you have an iOS device that syncs with contact & calendar data on your computer you should migrate this information too. If that isn't possible create a dummy entry of each type in your new profile and iTunes should offer to merge the existing data from the device into the computer, otherwise the danger is that it will wipe the information from the device.
If your media folder has been split out from the main iTunes folder you may need to do some preparatory work to make it easier to move. See make a split library portable.
Should you be in the unfortunate position where you are no longer able to access your original library, or a backup of it, then see Recover your iTunes library from your iPod or iOS device for advice on how to set up your devices with a new library with the maximum preservation of data. If you don't have any Apple devices then see HT2519 - Downloading past purchases from the App Store, iBookstore, and iTunes Store.

How to Use Home+End Key on new short usb apple keyboard on XP

How to Use Home+End Key on new short usb apple keyboard on XP

it cann't do that. How can i set the Fn + <- be Home key
and Fn + -> be End key like on my macbook keyboard
thank you for answer

Easy, no need to be harsh. I might not be a Level 9  Discussions user, but I’ve been an Apple Technician for more than a decade now. So believe me, I know what I’m talking about. Be it OS X Server or emptying the Trash. But even I come here from time to time to learn from others. Well, back to topic and being a little more specific:
The 'My Info' setting always belongs to the first iCloud account you add to an iOS device. In this account you create at least 1 contact, the one you will be using for 'My Info'. You then do the same on your other iOS device using NOT the same iCloud account, of course. You only need to enable contacts syncing in iCloud preferences for these primary accounts. From here on you can use differing 'My Info' on your 2 iOS devices without a problem.
But you may know that you can use more than one iCloud account at a time. Only the primary one will offer all iCloud options like Photostream. But what they all offer is contacts, calendars, etc. So if you intend (and I did) to share these 2 between your devices you can add them using a second iCloud account to both of your iOS devices. This makes it 3 accounts all in all. You could even go further and add another one just for 'Find my iPhone' if you like.
I would’ve used the built-in sharing of Calendar.app instead, but Contacts.app does not (yet) offer sharing contacts with others. That’s why I went with the third iCloud account as a secondary account to both iOS devices.
Apple of course recommends using just one Apple ID for everything to make it easier. But in some scenarios this just won’t cut it, which is even described in one of their support documents.
I hope that now you have an idea what I’ve done…
Good night
Björn
PS: It would be nice if people did not insist on being right. They too can sometimes learn something!

How to use labview with the handyboard

Hi,
how to use labview with the handyboard
Thx...

I'm assuming you're talking about this, since you didn't provide a link for those of us who don't know what you're talking about.
As the other poster said, you didn't say how you want to use LabVIEW with it. If you want to write LabVIEW programs than run on the microprocessor, then you're out of luck. If you want LabVIEW to interact with it, then you've got a couple of options, SPI probably being the best, but it also has DI and AI that you could use to communicate with it - the DI's could be used as a parallel interface.

Sir
We were able to solve that problem...but now could you advice as to which DC power supply we should use (preferably avalable in India) so that it can be controlled by Labview (through a gpib/rs232/any other port) to give a square wave of desired frequency/other parameters.

How to Use LABVIEW charts with Mathscript

Hi,
   I recently tried to work on Mathscript and it is really amazing. what I tried to figure out is:
    Instead of plotting using traditional "plot" statement, how to use LabVIEW chart ( I know how to Add output but the graph were not as expected
Is there any mean to get rid of this "Lengthy" delay that "ALL MATLAB User know" for first time compilation?
Thanks in advance

Well Chris,
         I was about to post the solution, but as I said, I'm in a middle of experts
It took me 3 hours to figure it out. I should've checked your answer . I resolved to the same suggesstion of yours. I only added some functionality to get the newbies like me being acquainting with how easy to work with LABVIEW mathscript based on MATLAB knowledge.

How to use LabView to control Primera Bravo II CD burner?

I am trying to use LabView to control the Primera Bravo II CD burner and label printer. The software that controls the Bravo II is PTPublisher. How to use LabView to communicate/control the PTPublisher? Please help, Thanks

Hi Qian,
I installed PTPublisher on a virtual machine, and I was wondering what kind of tasks you wanted to control within LabVIEW. From the program GUI, it appears like the only way to access functions is via mouse clicks. Do you know of any other way to control the Bravo II CD burner besides the PTPublisher software? If not, does the PTPublisher allow you to control it in some way other than clicking?
