With the API c for linux, how can I decimate the clock at a 10 kHz signal?

Hiya.  I know that the clock signal is decimated on the chessboard in a few places... is there a function in the linux api c for export a decimated signal?  Can I choose any arbitrary decimation, or am I limited to the various bases of time used on the map (a series of M in my case)?

Thank you!

You use DAQmx (8.0 or 8.0.1)?  If so, you have a few options:

Counter output:  Available frequencies are {80 MHz, 20 MHz, 100 kHz, external} / {2: 2,32-1}

Output frequency:  Available frequencies are {10 MHz, 100 kHz} / {01:16}

Export clock of AI or AO task:  Available frequencies are {external 20 MHz, 100 kHz,} / {2: 2,32-1}, but going too fast will result in a material synchronizing error on ADC or DAC.

On the M-series: DAQ there are two counters, a single frequency output, HAVE a single timing engine and a single engine timing AO (if your motherboard supports AO).  Simply choose any subsystem available to you.  If you have need of a constant 10 kHz and then the frequency output is perfectly adequate, it is programmed similar to a meter output (reference Dev1/freqout instead of Dev1/ctr0).

If I remember correctly (I'm on Windows for now), on Linux the C ANSI DAQmx examples should be installed in \usr\local\natinst\nidaqmx\examples.  It should be an example of output included continuous meter.

Best regards

  • How can I use internal clock case OR USB - 6259 BNC for the acquisition of digital data in my own big software?

    I want to integrate the ANSI C sample program ReadDigPort - ExtClk.c in my own big package.

    I want to use the internal clock of the BNC NI USB-6259 (.. 80 kHz 120 kHz).

    In the document:
    High speed M: Series Multifunction DAQ for USB - 16-bit, up to 1.25 MECH built-in BNC connectivity. / s,.
    is written:
    Or sample DI source clock: Any PFI, RTSI, HAVE sample or convert clock, AO, Ctr n out internal and many other signals sample clock
    The digital subsystem doesn't have its own dedicated internal synchronization engine. Therefore, a sample clock must be provided another subsystem on the device or from an external source.

    How can I use internal clock case OR USB - 6259 BNC for the acquisition of digital data in my own big software?
    With what other subsystem on the device can generate a source of the clock? How?

    It is possible to set a clock on an internal counter (for example ' Dev1/ctr0"):
    Creates channels to generate digital impulses that define the freq and dutyCycle and adds the channel of the task that you specify with taskHandle.
    DAQmxCreateCOPulseChanFreq (taskHandle, "Dev1/ctr0" units, clockName, idleState,
    initialDelay, freq, the duty cycle); works

    But it is not possible to drive this internal clock to a terminal (for example "/ PFI0/Dev1"):
    DAQmxErrChk (DAQmxCreateCOPulseChanFreq (taskHandle, "/ PFI0/Dev1", clockName, units, idleState, '))
    initialDelay, freq, the duty cycle); does not work: error DAQmx: measurements: type I/O of the physical channel does not match the type of I/O required for the virtual channel you create. Name of the physical channel: PFI0. Name of the virtual channel: clock

    The sample clock source can be derived from an external terminal (for example "/ PFI0/Dev1"):
    Sets the source of the sample clock, the sample clock rate and the number of samples to acquire or generate.
    DAQmxCfgSampClkTiming (taskHandle, "/ PFI0/Dev1", maximumExpectedSamplingRate, DAQmx_Val_Rising, ")
    DAQmx_Val_ContSamps, bufferSize); works. Acquire or generate samples until you stop the task

    But it is not possible to derive the internal counter of the clock (for example ' Dev1/ctr0"):
    DAQmxCfgSampClkTiming (taskHandle, "Dev1/ctr0", maximumExpectedSamplingRate, DAQmx_Val_Rising,
    DAQmx_Val_ContSamps, bufferSize); does not work. Error: Acquire or generate samples until you stop the task: make sure that the name of the terminal is valid for the specified device. See Measurement & Automation explore valid names of terminals. Property: Property of DAQmx_SampClk_Src: DAQmx_SampClk_ActiveEdgeSource device: Terminal Source Dev1: Dev1/ctr0

    Hi datafriend,

    using what it says is correct:

    Or sample DI source clock: Any PFI, RTSI, HAVE sample or convert clock, AO, Ctr n out internal and many other signals sample clock
    The digital subsystem doesn't have its own dedicated internal synchronization engine. Therefore, a sample clock must be provided another subsystem on the device or from an external source.

    This means that if you do not use an external signal as clock you can use the sample clock to HAVE it on board or at the output of the internal counter.

    There are also 2 ANSI C examples in this regard:

    http://zone.NI.com/DevZone/CDA/EPD/p/ID/4485

    http://zone.NI.com/DevZone/CDA/EPD/p/ID/4488

    So in both cases you have to use a fictitious task you need only for the generation of the internal clock (HAVE or CTR)

    Hi andypily1,

    Welcome to the Microsoft Answers community.

    Try the steps one by one and check below.

    STEP 1:
    How do I add or remove games in Windows XP
    http://support.Microsoft.com/kb/307768
     

    STEP 2:
    In most cases if the games are deleted from the computer files will remain on the computer.

    I suggest that you are looking for game files in the system32 folder.

    Later, click on Start menu click on run and type c:\\windows\system32 in the following search of the window for the file of games like free cell. If you get the files in the system32 folder then copy the file to c:\\program files\start menu\ later in the game folder.

    STEP 3:
    If fails it above steps, try a system restore to the point when the game was available on the computer.
     
    See the link below to learn how to perform the system restore.

    Hello

    The folder N360_BACKUP is not here and should be deleted or moved to another location.  The file is created by using Norton backup, so this utility should be configured to store its backup files into a directory on the C partition or to an external device in order to avoid the warning of low disk space you may have been found.

    When sharing my project there are some clips that show a red screen with a camera saying error. How can I solve these clips if I can share the project correctly?

    This happens usually when the import process was not completed. If you have the original camera card - or a copy of the computer of the map - you can probably use the re-import command (on the file menu) to fix things. In addition, it is possible that the original media is imported, but this transcoding was not. If you have chosen to optimise upon import, try to select clips in the browser and transcoding to optimized.

    You can activate it without a SIM card. If it is locked, it takes a SIM card by the carrier, for it is locked. The SIM card should not be linked to an active line of service, but it must be present to activate it.

    I want to install the 64-bit Microsoft Office but it ' s telling me that it is may not be installed with Microsoft Office Click - to - Run how can I install it?

    Hello

    First of all, make sure that your windows system runs as a 64-bit system. to check this out right click on computer > select Properties > check if it is 32 bit or 64

    absolutely if your system is a 32-bit win 7, you cannot run 64-bit applocation on it.

    If you are sure the config. You can install microsoft office instead of automatic execution of .exe or .msi file

    to achieve this can right click on your installation CD click on explore or open

    in the new Page, you will find the file .exe or .msi that you can use instead.

    Please let me know if your problem space or not.

    And by definition, a GIF image is optimized! A GIF is not the same size of the PSD file, and you are mistaken in thinking that you want it to be. If you are trying to achieve the slightest loss of quality, regardless of the size of the file, then you need to adjust your settings to save for Web.

    When I send several documents for signature, how can we separate these documents again once I got the signature for each of them. Its way easier if I send all together, because the signatory needs to sign once and then just click on the other signature fields, but if I separate documents, how I divide again?

    Hello Anna,

    If you have a professional account, there is a feature that you can enable to recover separate documents. You can go to the account-> account setting-> general framework 'Keep the separate documents' and select Save.
