Anyone have an example of a PCI-6250 Digital and Analog Aquistion with Analog Post-Trigger?

Hey All,
We're trying to set up a post trigger data capture of parallel absolute strobed Gurley 17-bit encoder data (ignoring MSB for 16-bit aquisition) with an analog signal that is the output of a torque load cell. The trick is to use the analog signal level as a post-trigger to stop the data aquisition.
1) can the analog signal be recorded and used as the trigger?
2) does anyone have an example using the PCI-6250 (or 6251)
Thanks in advance for your help,
-Drewksi

Hi Drewski,
You can use the APFI0 line as an analog trigger for your signal. However, in this case you need to connect your analog signal to both the analog channel you want to acquire at and the APFI0 line.
Assuming you are using LabVIEW,you can check the "Acq&Graph Voltage-Ext Clk-Analog reference.vi" example. This examples uses an external clock but it works also with the internal clock. All you have to do to change the control to onboard clock.
You can find this example in LabVIEW Help >> Find Examples >> Hardware Input and Output >> DAQmx >> Analog Measurement >> Voltage
Best Regards,

Does anyone have an example of a c++ TCP/IP client that works with labview TCP?IP server ??

I have the labview TCP/IP client/server working fine, but now I need to do this were labview is the TCP/IP server and the c++ program is the client. Does anybody have a simple C++ TCP/IP client that works with labview TCP/IP server ????

Thanks, you were right, we modified the c++ program to include the port # in the IP address and it worked.We also forgot to convert the port #. I included my labview and c++ program.

Does anyone have an example VI about how to call the animatewindow function in the user32.dll using CLN in Labview?

I want to call the WinAPI function-animatewindow in user32.dll to produce some special effect when showing or hidding windows, but i don't know how to using this Win API to achieve my purpose?
Does anyone have an example VI about this application?
Thanks in advance for your help.

You have to use the Call Library Function Node to call Windows API functions. The animatewindow function itself has some pretty simple parameters. You first need to get the window handle. There are a set of Windows API Function Utilities (32-bit) for LabVIEW that you can use. In there there is a VI (Get Window Refnum) that gets the window handle. It's a simple call to a Windows API function. You would call the animatewindow function in the same way. In this case there are 3 parameters: the window handle (returned by a FindWindow API call), a DWORD (32-bit integer) for the duration, and another DWORD for the flags.

Is anyone have an example code on CAN Periodic Transmission

I'm looking for an example code for a CAN periodic transmission in Labwindows CVI, because the example deliver with NICAN is not interesting for me.
If anyone have an example code,

Hi Lilian,
The Obj2Obj.c example shows how to configure a CAN object for periodic Tx (one frame each second).
In this case, the write queue length is set to 0, which means that the last written value is transmitted. You can set a non-zero queue length to transmit a set of frames.

Does anyone have a suggestion for an alternative to iCal that will interface with the Cloud? I find iCal to be poorly designed and not very efficient.

Does anyone have a suggestion for an alternative to iCal that will interface with the Cloud so it works on the iPhone and the Macbook? I find iCal to be poorly designed and not very efficient. I waste a lot of time entering information because you can't go to a specific day and enter information, nor can you navigate between months and add information on a specific date by clicking on the date. You can't easily scroll month-to-month and once you do by scrolling through nine months to get to where you want to be, you cannot enter information by clicking on a specific day in the month and entering information. I just called Apple and they verified that this is the way it works. You cannot go to a date and enter information, you keep getting thrown back to today and then you have to go into the calendar and change it manually on the screen. It is just not efficient.

APC, CyberPower are reliable.

My iPad2 has repeatedly refused to update to iOS7, whether connected to a PC or not. The error message indicates an unknown error has occurred, with error code 6. Does anyone have any idea what the problem might be and how to solve it? Many thanks.

Hi
I followed this guy's instructions and it worked:
http://evsiphone.blogspot.com/2009/05/iphone-iphone-could-not-be-restored.html
I did disable the security (AVG and Zone Alarm) when I tried on my own PC. My wife's laptop which eventually got it working also uses AVG and Zone Alarm but on an XP O/S whereas my PC is Vista - maybe this is why.
Cheers for you help.

Karsten, I mentioned "IPHOTO to IMOVIE" photo transfer.
In fact, you did not.
We had NO idea if it was a photo or a pocket-camera movie you were trying to import from iPhoto.
You also didn't describe what happens when you try to import.

when i click on the photo icon to import them...i see pics from previous imports only., but not the current one that iam attempting to import. It is not an device issue.
this just started happening when i updated to "IMOVIE 11"
OK, that's a bit more information.
iMovie was probably already running when you imported the pictures into iPhoto and wasn't aware of the last import.
Try to quit iMovie and iPhoto, then launch iMovie again. The last import should show up.
Please take a few seconds to proof read your posts and also make then easy to read (no large letters, no underlining, no double line breaks in the middle of a sentence etc).

How do you transfer voice memos to your pc? I have synced my phone a number of times and everything updates with the exception of voice memos?

How do you transfer voice memos to your pc? I have synced my phone a number of times and everything updates with the exception of voice memos? Also, my voice memos are checked to be synced everytime my phone is synced.

Voice memos, once correctly synced, will appear under your Music Library. Can you go through your music library to check?

Does anyone have an example to share of using a variable in a proc call?

I would like to use a value from a table to call a procedure in ActionScript. Can anyone share an example with me? TIA,
Deb.
(For example
var proc_name_from_table:String;
var command_proc:String;
command_proc="mx.core.FlexGlobals.TopLevelApplication." + proc_name_from_table;
command;
Or something like that (just to give you an idea where I am heading).
It is for a site map application that gets values from a table and I don't want to write a huge if statement with specific, hard-coded calls.)

Does anyone have an applet that runs on Windows CE and connects via jdbc to lite DB

I am trying to get an applet to connect to the Oracle lite DB
I use
     if (conn == null)
     // Load the JDBC driver
Class.forName("oracle.lite.poljdbc.POLJDBCDriver");
     conn = DriverManager.getConnection ("jdbc:polite:polite", "SYSTEM", "MANAGER");
     output.appendText ("Connected\n");
but CE just echos oracle.lite.poljdbc.POLJDBCDriver and does not connect.
Does anyone have any working samples? I am using Jeode JVM on the CE device

We have the same problem with that platform, but we get a
java.security.AccessControlException: access denied (java.lang.RuntimePermission loadLibrary.oljdbc40)
exception.
Thank you in advance.

Does anyone have a disc / installation file of Adobe CS4 and may make it available / sell?

Does anyone have a disc / installation file of Adobe Photoshop CS4 and may make it available or sell? I bought a group license in 2009, I've got serial number and certificate but unfortunately I've lost the cd. Now I have to re-install the application. Adobe does not support this version any longer and does not provide download file or CD of CS4. Could you help me?

You can download the software from this 3rd party website

So does anyone have any info on if apple know about all the problems with the iTunes update?

By problems I mean:
. The unability to sync music from your laptop/computer to your apple device
. The slowness
. Unable to log in
. Being told that the laptop/computer being used isn't recognised
. Clicking on music and it flicking through really quick without playing and then not playing after, but still being on apple device.
+ all the other problems i've seen mentioned on this page. It's pretty clear the new updates have glitches that urgently need fixing and a lot of people are encountering some or multiple of these problems.
I've not seen or heard any announcement whether they know or not or if they're doing something to fix this, because they need to. Urgently.

Hi JamilMereck,
first of: you can edit previous posts in a time-frame of some minutes (haven't measured it ...).
After that they become non-editable.
I admit I have used microphones some years back with and without PCs (have switched to Macs 2.5 years ago).
But I always had the mics connected to a mixing desk, which provided Phantom Power.
Since I gave up my 'Singing Career' (wasn't good enough) I also abandoned the use of microphones.
To your questions:
It might be that PCs with specified Microphone-In ports are also providing power to them or the microphones themselves do not need any power.
And the 'compatible with...' refers to the usage on computers in general.
The iMic from Griffin works with OSX 10.5 (scroll down on the webpage to 'Product Compatibility' the left icon symbolizes OSX 10.5).
As said above, I am no longer up-to-date in usage of microphones, but when you want to use a microphone with the standard connector you have to get either a microphone preamp or a mixer.
If you use the mic only (really only) with your Mac Pro, you might wanna look for USB-connected mics from Samson or Audio Technica for example.
And don't get upset, I understand you fully and any kind of 'insult' is for the manufacturers and not for me

HT201250 Anyone have time machine "lock up" while backing up and not completing the task?

I have the drive connected for over 24 hrs and time machine will only back up 25% of the 75Gb it claims to need to back up.
I have re tried and get the same result, and T.M. will show "backing up" even after 24 hrs.
I know it is not the drive being too full or being defective, since a partition set up for a pc works just fine.

Hi, many people have, but I think you need to Repair the TM Partion, & maybe your Boot drive, maybe more.
Have you looked through Pondini's extensive TM help site?
