Counters play ping-pong. Argh!

I know I'm missing something very simple. I'm fan of tensions in parallel with 2 Agilent 34401, 3 serial ports, and 4. I am only trigger 1/s, but the counters back, acquire style table tennis. I don't understand this. Both get the same trigger. I just need to make a simple A / B math work but cannot since both voltages must be read at the same time. It's driving me crazy.

Thank you all for your comments. I had to dig a little deeper in low level vi trigger. Part of my problem is logistical. I have no material in the development computer. I write it here, create the exe, Sandalenet more on the floor and the test. A lot of exercise, but not a lot of fun. That's what works. The operator is happy. That is all that counts, right?

  • How can I gradually accelerate the expression of ping pong?

    Hello

    I have two key frames and I use it to repeat:

    loopOut ("pingpong")

    Is there a way I can gradually reduce the gap between the two keyframes?

    So, for example if I have a circle from the left of the screen to the right of the screen in 4 seconds. I want to speed up so that the end of the timeline, it only takes 1 second to make the move.

    Ideally if I could bind the speed of a cursor on a null object would be great!

    Any help?

    The best way to achieve this effect is to precompose the effect layer, or layer to effect and the adjustment layer, and then time-remapping the demo.

    Of the description and in my experience, there is nothing that advance composition must be interrupted in your project. If you want the background are not affected then do not include in the demo. If there is an effect, say something like a glow that bounces exhibition that you're applying for some background images, so you can just before dialing your adjustment with the LoopOut expression layer, condense the transformations, turn the demo in an adjustment layer, and then time-remapping and use the graph Editor to adjust the ramp.

    This will keep the background images play in real time but ramp to the top of the loop of pingpong.

    I hope this helps. This is a project of CS5 to show how's done it.

  • simple pong game

    Hello!
    I have problems with my game of "ping pong" ( http://en.wikipedia.org/wiki/Pong) programming in flash. I wanted to know what is the correct way to do the drawing and flash synchronization actions. I used the timer (with each click Timer, "ball" is in motion), but this causes a flicker or if I descrese the timer interval, then the "ball" is moving too slowly. I was told to use threading, closures and delays. Is this correct? Maybe someone has some samples for this or a similar program to flash?

  • Artifacts panoramic angle Surround Automation

    Audition CS6, Win 7 Ultimate x 64, Z820, sound card Soundblaster Recon3D PCIe, Altec Lansing 5.1 speaker system.

    I'm automating a surround panning angle on a stereo track, and when I reached + 90, keyframes to jump from the top of the screen to track down and vice versa, envelope as shown in the picture following and as indicated by White arrows.

    Au.jpg

    When I play this back to each of the points where the keyframes will jump (at arrows), I hear an artifact in the sound (in my case, it always seems to be in the LS channel). I repeated it over and over, and in some cases to the reading, I can see the hold panner in fact jump from one side pan to another instantly when the artifact is heard. In other cases, where I cross this border + 90 several times in a row (that is, come and go through it), I can hear an unnatural ping-pong effect in my field surround sound. In other locations, the movement of the sound is smooth. Appears not to occur to the jump from top to bottom and vice versa. It's almost like hearing isn't sure where to play the sound, and (sometimes), it switches to the wrong side of the field. Oh, and another thing, this is not always consistent. It can happen once, but not the next playback at a particular place in the noise.

    Everyone experienced it, and is there a way to avoid it (except the obvious solution of "don't do that")? Any help would be appreciated.

    See you soon,.

    Shane

    OK, so I think I knew what is causing these artifacts. I started thinking about keyframes on each side of the jump, and that the hearing could be between them (i.e., on the line of steep slope between them from the top down). I zoomed in bulk and I noticed that they were not quite vertical, so I grabbed the bottom just before the first jump from the bottom to the top and not moved until it is is stopped (or created some odd number of lines), pushing "next to one of the other" keyframes in time the (or at the same time (, I don't know which), and when I played it back, I heard no artifacts. This removed the artifacts entirely or just made small enough to be imperceptible. If I move the keyframe of return so that it is no longer vertical, once more to get the artifact. I repeated on the other two arrows, and the same thing happened: the artifact went missing when the break lines were vertical.

    This may not appear for many people, depending on your panoramic range. But I was panoramic a wind howling its all around the room at random, so my portico covered the gamut. In any case, I now can at least go back and eliminate artifacts manually after you use the pan to WRITE the pan on the track automatically.

    See you soon,.

  • Hard drive MacBook Pro broken?

    Hi all

    Last night my Macbook hung - spinning wheel and non-sponsive so difficult to hold down the power button and I think I have hard disk problems:

    I get the grey folder flashing when I start.

    Boot in safe mode does not work.

    Boot in Apple Hardware test does not work

    I can boot to OS X Utilities (cmd + r) and have tried to restore from a backup and it does not find a local disk to restore. I have a backup stored on the time machine.

    I also tried to restore Mac OS X from the same menu - and even when it does not find a local disk to restore.

    I ran disk in the same menu utility and I do not get an option to check the disk (in gray) or erase disc (also grey).

    Can anyone advise on the next steps before I take it down to the Apple store? Far from being a guru on this stuff! MacBook is 13 "and 5 years with 512 MB hard drive. Ran the Mavericks.

    Thanks in advance!

  • Time Machine crashes during backup

    Hi all

    I have a crush of Promise Raid connected to a Mini Mac OS X Server 10.9.5 (Mavericks) running. I have two volumes of backup Time Machine, 1 is a partition of the Raid itself, and the other is a 5 TB USB external drive. The goal was to have Time Machine backup ping-pong between the two. And for a while, that's how it worked.

    After about a week of reliable backup, Time Machine will now just hang it on a point in the backup and do nothing. I let it run for as long as 2 weeks just to be sure, but it never moves. I have to jump the backup. Then, it hangs on the other disk in the same exact spot.

    I tried to reformat completely each player and the best I've managed to do is backup successfully for nearly a week. Readers have enough space, but for some reason, the backup no longer works.

    I've been struggling with this for over a year without success. The worst is that when I think that I have work, I return back to retrieve something and find that he has not worked for a week (or more). Very frustrating.

    At this point, I'm looking in a 3rd party like Carbon Copy Cloner utility. But I like the ease and the Time Machine product structure. We do hard backups on DVD, so it's really just for jobs, we kept on our server that exist for about a month before be saved permanently.

    Thanks for the help,

    Rob

    I think maybe it's time to give up that hard drive and get a new start.  You might be able to fix it, but I wouldn't try to fix it without already having another backup in place.    The fact that it failed sporadically for more than a year is not a good thing.  Always have at least two copies of any data that is essential at all times *:

  • locked mac using iCloud with 6-digit access code

    Children on vacation had access to one of my macs and therefore locked this macmini via iCloud and so created a 6-digit password that we obviously do not (they have never written it down).

    Having spent 5 hours on the phone with Apple support (including a screensharing away where they could see that I can still connect to my iCloud account, proof of purchase and so on) they sent me to the Apple store, I did. Nevertheless, they said that they are unable to solve a problem of iCloud in the store, it must be done online through the Apple Support (feel like a ping-pong ball now...).

    So I called the Apple support once more and 30 minutes later... they tell me very well and everything I have to go to the Apple store...

    Thank you in advance for help.

    You can request support for a file number so that you can submit it to the Bank, they can then (probably) communicate with each other and sort things.

    A small note, even with access to your Mac, your children could not lock a device associated with your account without knowing your password to iCloud. This isn't a good idea, I suggest when you get this set, you change your password and do not tell your kids this time.

  • Synchronization semaphore

    Hello! I have a question about the order in which the semaphores are acquired and released. I looked at the example of the semaphore and from what I can figure out the order which the semaphores are requested are respected.

    I have two processes and they must run one after the other. These processes are separate screws and an indeterminate amount of time to run. I have a semaphore that is caught by a single process, released, grabbed the other process, released and so on.

    My question is this. How can I be sure that just after that a process releases one semaphore, the other the catch? Is there a chance that the very process that just came out the semaphore can re - acquire the semaphore before the other process could apply?

    Am I banking on the fact that the time it takes to complete the request, after the liberation, is always less than the time needed to run the code in my approach?

    Thank you!

    PS. I tried to find more documentation in addition to the help file and the example of semaphore pre-loaded onto implementing semaphores labview. If anyone has any other docs who would think would help to clarify labview semaphore concepts do not hesitate to send them my way

    If you still want to have a configuration of ping pong, where runs A, then B, then A, etc, then I suggest to create two queues - one for each process. Initially, each process remove its queue with an infinite time-out. Because the queue is empty, it will be forced to wait until there is an element in the queue. When the process is complete, we place an item in the queue of the other process, which will allow it to resume.

    To initialize the system, will be given an element in A queue.

    The same concept can be implemented using several other methods, but I think that the queue is the easiest.

  • AVT Guppy 033 B device is the same image twice on the &lt; Session Out &gt; event: Frame made

    Sometimes the event gets the same image twice, but with an increase, correct the image of the index (see photo index 125, 126).

    We work with the latest Labview and Vision version 8.6.1 could the firewire driver cause this problem. We use the original driver

    Microsoft XP, SP3. Should install us the driver of the TRA instead, other suggestions?

    Thanks for any help.

    Syn66,

    Looks like your code without taking into account the fact that the Images are passed by reference. It seems that you still spend the same image GetImage and then put it in your queue. Each iteration you will be overwrite the content of the image of the singular and all the elements in the queue is pointing to the same data of the image.

    If you want to structure your code like this, you'll probably want to create an image of each iteration of the loop, call GetImage use it and then put it in the queue. When you treat it and get out of the queue, you can then destroy it. You can optimize the image allocate/free sentence (which may or may not be meaningful) with a strategy of ping-pong by having a separate queue images empty and then you delete the images of this queue empty, GetImage to use and place it in your existing queue of images to process. After the treatment, instead of simply releasing them you would put them back in the empty queue.

    Hope this helps,
    Eric

  • Sends the data sequentially to the FPGA to a file during playback

    Hi all

    I am a new user of the Labview FPGA module, and I need your help.

    I have a huge file in my computer and I want to treat my FPGA Module. I have a VI divided into small files first, but to my FPGA I do not know how. My idea is to create two blocks of memory in the FPGA in order to have a structure of Ping-pong, module while the second memory is written the first memory was read and the data is processed.

    The first problem is to forward these data to my blocks (as text and the FPGA does not accept it).

    The second problem is that I don't know if as it is made of wiring will work. Can you help me it wiring? I don't know if data should I wire in the host of the read method will go directly to the data items in the FPGA VI.

    Created memories are 64 MB each. I work with FlexRio.

    Thanks in advance.

    Greetings from King,
    Miguel.

    What you want to do, is create a DMA FIFO to send data down to the FPGA.  Make the data type of the DMA a U8.  Thus, on the side of the host, you just read your data from the file, use the array of strings of bytes and write to the DMA FIFO.  On the side of FPGA, you read DMA FIFO inside a loop TO make your table and then treat.  You may need to use a different DMA FIFO to send data to the host computer.

    Hi nellooo,

    Here's the "autoindexing" and "loops" at stake!

    Use a loop FOR autoindex on your input string array. (And you need a control of the chain, not an array of string constants array.)
