Fastest sampling (software controlled)

Hello

I'm reading of data an accelerometer to Codemercs JoyWarrior 24F14. LabVIEW connection was easy as can be and reading to him as well.

I want to use the sensor to measure the vibrations in one of our machines, so - as a test - I placed on the top of my iphone and called him. When I run the loop uncontrolled I have more than enough samples. So much in fact, that I see no vibe at all within 100 samples.

If I run the loop with a 1 ms timer, I get too few samples to acquire vibration clearly.

Is there any increase in the frequency of sampling a bit how for example by a timer µs? Another way?

You already use the producer-consumer-Structure.

The "upper" loop writes the data to the producer = queue.

The "lower" loop reads the data from the consumer = queue.

Calendar of the loop faster than milliseconds is impossible in LabVIEW as LV uses the time base (smallest value = 1 ms) Windows.

I replaced the while loop with a timed loop and you try to run this loop with different periods.

The timed loop to run with a higher priority than the while loop.

I hope you have LV 2009

  • Is it possible to create a TabPane without tabs or paging control without control of the page (software controlled)?

    Trying to get my head around swapping scenes and one thing I see that is already coded and there is more intuitive controls paging and TabPane.  However, I would like to be able to create a vertical toolbar this page of controls or view tab.

    Is it possible to create a Pagination without control on the page?  Or is my guess of the Pagination control resizing so that the lower part is outside the window that opens, thus masking information page?

    Or, is it possible to create a TabPane with signs, but not the tabs?

    Can you explain more in detail what you try to do? Point of paging is to provide control of page features, and the point of a tab pane is to provide the functionality of the tab.

    If all you try to do is spend the different points of view, just add and remove views of some component layout. The easiest to use for this is a BorderPane, because it provides the methods set for different regions.

    For example:

        }
    }
    

    If you do not use a component of border for the overall design, you can embed just a BorderPane in your page layout and let the top down, left and right vacuum. Or you can use any component you like feel and simply call pane.getChildren () .setAll (view) to change the view.

    There are a few kicking around for this feature mini-cadres (others might recommend to some, I'm not really familiar with them) but I generally find it quite simple to create from scratch whenever I need it it seems not really interesting to use the third party for this code.

  • High speed continuous measurement of encoder with sampling frequency of 1 kHz

    I am able at all times the position of a linear encoder using a PCI-6602 counter card, and I need to know how to set up so that the counter rotating at high speed, but the data is inserted into the buffer at a frequency of 1 kHz.  I am able suddenly to a hydraulic cylinder, and I am not concerned about the event recording to high frequency except to the extent where they throw off the number considerably if the equipment does not run fast enough to detect all the impulses of the encoder.

    Now, I think is that the external sample clock signal control (routed internal pulse output counter) time rate whereby the equipment detects the impulses of the encoder and the rate at which it inserts data into the buffer.  With a pulse 100 per inch encoder and a sampling frequency of 1 kHz, the extended final position of the cylinder is turned off by +/-0.15 inches, which is unacceptable.

    I need calculate a speed of this information, so I prefer not to use software timed sampling to control this (it's more difficult programming for other reasons as well - several asynchronous measures).  Any ideas on how to configure the hardware to count faster than the speed at which she inserts counties in the buffer?

    OK, you're clearly on the right track here, so I will focus on some details.

    1. How do you know that the +/-0.15 "differences are * measurement error rather than * error of movement?  Why wouldn't be an accurate measure and a proposal which can vary slightly from the nominal value?

    2. I wonder some all electric noise and defects that may produce false edges.  The fact that the behavior was better by using a sampling rate limited (200 kHz) in the digital inputs may be that some of these flaws were so short that they were never captured.

    I did a ton of work with the Commission to 6602 encoder and I can certainly confirm that count equipment is sensitive to the edges in a few tens of MHz.  (I know its 80 MHz for edge counting, but I think I remember that it can be of the order of 20 to 40 MHz to accommodate the time of signal propagation extra of the quadrature decoding circuit).

    A small point of clarification.  You're talking about the speed at which the meter "works to.  The value of count is a register whose value is changed completely by the circuit, * independent * of the sampling frequency.  If you enjoy with material-clocked County in memory buffer or interrogation of software without buffer not a bit for circuits that increments / decrements the value of the counter register.  (In other words, I am completely convinced that you would get commensurate with position end even if you took only 1 sample software-polled after the end of the move instead of sampling at 1 kHz all the way through.)

    So, if the value of the counter is disabled, it is because the circuit detects producers of County of the edges that shouldn't be there.  Something you can try is to set up digital debounce filter for input lines of the PFI corresponding to the encoder Source inputs and to the.

  • Question DAQ sample rate

    Hello

    I tried to understand how the 'number of samples' and 'rate' controls affect the frequency of sampling for the DAQ hardware. For example, say I want to acquire data from a sensor of pressure at a frequency of 10 Hz intuitively, I would think everything I do is on the desired sampling frequency, in this case 10 Hz control the 'frequency', try this, I know that's not true. I read that 'number of samples' affects the sample rate by setting a buffer value that must be reached before the VI will process the acquired data. So I also tried to set the "number of samples" to 1 and "rate" at 10, thinking this would have led to a sampling frequency of 10 Hz, and again, it is not. The only way I know to control the sampling frequency is using the wait function (ms), but then I always get buffer overflow errors.

    Can somone if you please explain to me the error in my thought process and also tell me the best way to control the sampling frequency? Is attached a simple VI, I am using to measure my actual sample rate and compare it to the sampling frequency that I am trying to achieve.

    The VI use the DAQ assistant to acquire data of pressure, inserts data into a table, and measure the size of the array. I'm then by dividing the size of the array by the elapsed time in seconds for the sample/s (I'm also dividing the number of iterations of the loop by seconds and using it as a comparison). I compare this value to my entries for the 'number of samples' and controls 'speed' in order to give a sense of the role they play in sampling rate. The VI also allows to choose to use the wait function (ms), as well, using this function is the only way I can control the actual sampling frequency, but then I always get buffer overflow errors. Any information would be helpful, thanks!

    What is the device that you are using? My guess is that whatever you have, it does not allow such a slow pace and is failing at its minimum.

  • the trigger for camera AVT Pike-based software

    Hello

    I'm using labview 8.5, as well as the acquisition of vision (IMAQ-dx, latest version) software, to control a cross beam motion detector and AVT pike camera using a high speed cable IEEE 1934 (800mbps) b.

    I wish to have a trigger internal (software) control system and have no problem to get Boolean cross beam sensor signal or run indepedently of the camera (about 300 FPS).

    The problem is the trigger.  I have a problem with where to put the camera vi in the relation to the probe wiring diagram.  In the image as an attachment, I have the sensor in a loop and the camera, in a nested loop.  However, when I trigger the camera manually with a push button, the sensor stops running.  And when I try to control it with the sensor instead of the push button, I can boot, but cannot stop the camera.

    Basically, I just want to know if there is a method of internal trigger to control camera image recording.

    Ah yes! just before I read your reply I tried... and it certainly helped.

  • Sample interval finished PCI 6071E scanning

    Hello

    We plan to acquire data of an array of 64 pixels linear photodiode using PCI 6071E. Suppose we take 64 x 3 samples our sample rate is 1 ms/s (for 64 channels of avian influenza) and each group of 64 samples are separated by a time interval T * (see photo).

    Platform: WIN XP OS, DAQmx with C++, Int CLK

    For the big T * > 50ms we can set the device to take 64 samples each time and reconfigure the unit and prepare for the next DAQmxReadAnalogF64.

    For the smaller T * (say 2ms), the device may not able to reconfigure quickly enough that works properly. One can think of device configuration to collect samples of 64 x 3 and using external synchronization (using a delayed digital model) to care for the calendar

    (see attached "Sub PDA::Acquire()" C++ code, which can be changed to use Ext. CLK).

    but I post here in case any expert knows an easier way without adding hardware.

    The ideal solution, we expect to send a trigger for each set of 64 samples and controls the delay between each set of acquisition between triggers, but it is not possible to obtain simply by using this device.

    Thank you very much in advance,

    eLions.
