How can I use the DAQMX in combination with a FIREWIRE MIO?

We had problems in using DAQMX in combination with a NI FIREWIRE MIO Acquisition Card (according to an explanation of a NI-Consultant). Is there a way to solve that problem?

NI's manual claims there will be DAQmx support for firewire in the future. I hope so too.
Best,
Davy

How can I use the NI PXI-6508 with Lab View 7? what are the first steps to get started??How can I use the channels with lab view 7????

I have a 8 slot PXI system with 2 NI PXI 6508 and 1 DMM 4070 in it. I want to get started with programming the digital I/O cards (6508)! How can I use this cards with LabView 7?what is the best way to get started, or where can I get examples showing how to use the several channels?
Thanks!
Philipp

Philipp,
The best way to get started is to decide if you want to use traditional NI-DAQ or NI-DAQmx. Recently we released NI-DAQ 7.1 which provides NI-DAQmx support for the PXI-6508. In my opinion, NI-DAQmx is more efficient and much easier to use.
To get started with examples, simply launch LabVIEW and go to Help>>Find Examples. Then expand Hardware Input and Output>>DAQmx and select the appropriate digital group for your application. This should help get you started.
Please repost if you need addition assistance. Good luck with your application!

How can I use the remote that comes with MacBook?

I have a MacBook remote (old macbook, not the pro). I no longer have the macbook computer, but I hope I can still use the remote. I do not know how. Please help me.

Only if it has IR support. Otherwise, it cannot. You would need to connect an IR receiver to the USB port.

How can I use the MacBook Pro webcam with Windows XP apps under Parallel?

Thank you in advance for your help with this matter.
I have a MacBook Pro and I have just installed Parallel with Windows XP. I would like to use the webcam that comes with the laptop for applications that run under Windows XP (ex.: PalTalk).
The application doesn't seen to recognize the camera. Do I have to load the drivers for this camera in XP? If so where can I find them and what is the process?
Thank you again,
Enrico

You probably need to load the Boot Camp drivers that are on the Leopard DVD. Whether it works or not I can't say, but you may want to post your question on the Parallels forums, since it's not an Apple product, and if anyone has gotten it to work you'll find them over there.

How can I use the latest Berkeley DB with SQL API in PHP app?

Hi,
I'm a PHP developer and I already use Berkeley DB in my applications using the [DBA Functions|http://www.php.net/manual/en/ref.dba.php] . I'm very interested in the latest Berkeley DB release. How can I write a PHP program that uses the SQL API of the latest Berkeley DB release?

Hi Kurt,
I'm not a PHP expert (far from it), but the simplest way to get started with the Berkeley DB SQL interface is to run Berkeley DB's <tt>configure</tt> script with the <tt>--enable-sql_compat</tt> flag. This will create a library called <tt>libsqlite3.so</tt> that you can use as a drop-in replacement for SQLite at the API level. Database files still need to be converted with a SQLite <tt>.dump</tt> followed by a <tt>.read</tt> with the <tt>dbsql</tt> tool.
This should then allow the existing PHP driver and application code to switch over to Berkeley DB without any code changes by setting <tt>LD_LIBRARY_PATH</tt> to find the Berkeley DB version of <tt>libsqlite3.so</tt> ahead of SQLite. Note that any other code that relies on SQLite will also run against Berkeley DB with this configuration, which can cause problems if the system libraries use SQLite (for example, on Mac OS X). For that reason, a better long term solution would be for the PHP SQLite driver to have a mode where it loads <tt>libdbsql.so</tt> rather than <tt>sqlite3.so</tt>.
I hope this helps, please let us know how you go because I'm sure lots of other PHP developers will be interested in the answer.
Regards,
Michael Cahill, Oracle Berkeley DB.

How can I use the accordion panel widget with a footer?

Hi,
My question is may be not clear. So I'm gonna be more specific. I'm using a menu for my website with the accordion panel widget. The menu is working fine and when I'm opening it, it pushs the items below on the pages.
My problem is with the footer of the page. Because, when the items below the widgets are pushed, they go below the footer and the footer is not pushed.
Is there any way to pushe the footer when I use the accordion widget? I don t want to overlap it.

I assume this is what you want to achieve in the footer....
Make sure in Muse before you export that the panel is closed, and also as Brad suggested, make sure Overlap Items Below is unchecked. I would also check the "Can Close All" button.

How can I use the ni-6024-e with the real time of matlab/simulink. Where can I find any example?

I am doing the final project and I need to control the ni-6024-e with the RTW (real time) of matlab/simulink.
Does anyone know or have any example?.
Thanks

Rafelmor,
Have you contacted The MathWorks yet? They probably have the best information.
However, I did a quick search and found some information on The MathWorks' site. For Data Acquisition Toolbox examples: http://www.mathworks.com/access/helpdesk/help/toolbox/daq/daq_example_index.shtml.
For RTW information: http://www.mathworks.com/support/product/RT/.
Good luck with your application.

How can I use the pulse train from a 6602 to trigger an niFGEN and niSCOPE on each rising edge of the pulse train?

Hello,
Here is my application: I need to use a 6602 counter/timer to generate a pulse train of certain frequency and duty cycle. On each rising edge of this pulse train, I need to output an arbitrary waveform on Ch. 0 of an niFGEN (5422) AND acquire data from CH. 0 of an niSCOPE (5124). I also need to synchronize the niFGEN and the niSCOPE to the same clock used for the pulse train (6602/ctr0). This process needs to continue until the user stops the system.
I can generate the pulse train using the 6602 just fine using ctr0, but the pulse train shows up on OUT0 by default. When setting up the niFGEN and niSCOPE to trigger on rising/positive slope edge, OUT0 is not an option for either device as a source for the digital rising edge (pulse train). The main options for both are PFI0-3 and RTSI lines.
Questions:
1.) Is there a way that I can direct the pulse train to a location (such as an RTSI line) where BOTH the niFGEN and the niSCOPE can use it as a start trigger for each rising edge? I noticed in MAX that a route can be made between ctr0's internal output and a trigger line and others. If this is a solution, could you please explain how to accomplish this?
2.) Once I configure the niFGEN and niSCOPE to be triggered on a digital rising edge, how can I effectively have this happen for every rising edge from the pulse train? In other words, can I just initiate the FGEN outside of the while loop and it will generate a waveform for each rising edge it sees at the source until the while loop is exitted?
3.) Is setting a reference clock for the niFGEN and the niSCOPE the same thing as synchronizing both devices using the same clock that generated the pulse train? It is not clear to me the difference, and why it would necessarily be useful.
Images of my current front panel and block diagram are attached. If you would rather have the actual VI's just let me know. Any help and/or explanation on this is greatly appreciated. Thanks in advance.

Hello Cgifford,
Welcome to National Instruments Forums.
To output your signal to the PFI lines,
you can use external connectios between OUT0 and PFI lines. You can also use
the backplane to do so by routing into the same RTSI line.
1)
On the SCOPE and FGEN, the name of the
terminals are actually “PXI Trigger Line x/RTSIx” but on the 6602 you might
need to route the signal using the property:
You can also use the DAQmx route signal which perform the same opperation.
2)
This will depend on the frequency of
your pulse train. If this is lower than about 10 ms, then you can probably
place this on a loop and start and stop the acquisition every time. If the
frequency is higher than this, you will have to use:
- Scripting on the FGEN side (read more)
- MultiRecord Fetch (more information in the scope help file
section “Acquisition Functions Reading versus Fetching”).
3)
The short answer is yes. The longer one
might depend on how tight you need the synchronization to be (us, ns, ps). For
very tight synchronization, you should look into here.

How can I use the button in one panel to control the other panel's appearing and disappearing?

How can I use the button in one panel to control the other panel's
appearing and disappearing? What I want is when I push the button on
one button . another panel appears to display something and when I
push it again, that the second panel disappears.

You want to use a combination of three features, a button on the panel,
code to notice value changes using either polling in a state machine of
some sort or an event structure, and a VI Server property node to set
the Visible property of the VI being opened and closed.
The button exists on the controlling panel. The code to notice value
changes is probably on the controlling panel's diagram, and this diagram
sets the Visible property node of a VI class property node to FALSE or
TRUE to show or
hide the panel. To get the VI reference to wire to the
property node, you probably want to use the Open VI Reference node with
the VI name.

I am not positive what you did is going to work, but it seems like you did the equivalent of imaging a small disk on a bigger disk. In that case, the first thing to do is update the partition table with fdisk. Start with fdisk -l in the vm for general information about the disk. Hopefully, the additional space will show. Then, work with fdisk to use the extra space. The easiest is to add a partition, then a file system on it. It is also possible to expand the last partition (you might have to delete it first), then expand what is on it (may be RAID, LVM, or the file system), layer by layer. As usual with fdisk, you run the risk of thrashing it all, so you may want to practice on a copy first. Obviously, the extra space can only be added to the last partition of the small disk.
If the situation is more complex, you may have to boot a VM with both the small disk and the big disk at the same time. If you boot the VM off of an iso DVD image, you can then shell out, then run fdisk to partition the big disk the way you want, then use dd to copy the partitions you want in the order you want from the small disk. I am pretty sure not all combinations will work, but you get the idea. You can then take the small disk out, and boot off of the big disk.
Come to think of it, you might just be better off with adding more space as a second virtual disk. You would then be free to partition/format it the way you want without messing with the first disk. Linux is so good with disk management, so many options.
As a general statement, though, I like to put some distance between the high level file systems and the low level disk partitions, so I use LVM (Logical Volume Manager).
Best of luck, keep us posted.

How can I use the print module to print different size images on one large "canvas"?

How can I use the print module to print different size images on one large "canvas"? An example would be in Photoshop, go to file>new, and create the size paper I want, and move images of different sizes onto it.
I was thinking the print module would do this automatically for me.

You can't, at present. It's been a requested feature, so we'll see if it shows up in a future version, but it's not there at present.

I have an Apple MacBook Pro with 2 USB ports and a MiniDisplay Port. I also have an HDTV with a HDMI port. How can I use the TV as a display without any tethering wires between my computer and the TV?

I have an Apple MacBook Pro with 2 USB ports and a MiniDisplay Port. I also have an HDTV with a HDMI port. How can I use the TV as a display without any tethering wires between my computer and the TV? I have a MiniDisplay Port to VGA adapter, but there are two issues with it: The new display doesn't have a VGA port, and even if it did, I wouldn't want to have my mac constantly attached to the display by a cable. I was looking for a way to use the TV as a display without any wires. Is there some type of bluetooth setup I could use? Please let me know if you have any suggestions.

As I wrote above, I think you should look into the Apple TV yourself. The best place to find information about what it can and can't do and to ask your own specific questions is probably in the Apple TV forum, here:
