• Why used ONE of my animations race outside edge Animate

  I can't work this. Im trying to create a drag and drop game using edge animate/Jquery.

  IM following a tutorial to the letter, but none of my symbols is draggable when I saw.

  I downloaded a tutorial made in a previous version of edge Animate and it works fine until I have import in Edge animate.

  Once it's updated preview and then it stops working

  Can anyone help?

  If your draggable any transition, he will do it. You can't have an animation on your draggable on the main timeline. You can if it's a symbol as in my example. The animation is in symbols rather than on the main timeline.

• can I use a structure of the event in another structure of the event

  Hello

  Can use a structure of the event in another structure of the event?

  Thank you

  Viviane

  I would put your waveforms in the registers at offset.  You can then use your structure for the main event to trigger on the Show 1... the value change events and process the data, however you need from there.

• How can I use my PXI-6115 meter analog signal trigger to generate pulses of frequency

  I work on a PXI-6115 DAQ card and want to using the analog signal to trigger the counter it's generating frequency pulses. The manual says the analog trigger is supported, but I can't use an analog signal to trigger the start of work, in the test, I use the counter 0 to generate pulses and use the signal input port analog trigger PFI 0, can someone tell me what it is? My test VI. & error message appears in the attachment.

  Best regards

  If you read the error you can see digital triggers are the available trigger only when you use the output of the counter.

  You can work around this by setting up a dummy analog input task which will trigger an internal digital triggering when he sees the right analog trigger.

• 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)

• Continuous signal creation (using the PFI channels?)

  Hello

  I am new to the use of OR and its interfaces. I use the USB-6221, with its C API.

  I need to create multiple channels of continuous digital output with the cycle of the frequency and the duty.

  I used DAQmxCreateCOPulseChanFreq for the crt0 and crt1 channels and it works fine, but I need a few lines.

  Can I use the channels of the PFI (PFI0-4 for example) for this purpose?

  With the help of the DAQmxCreateDOChan I can set the PFI desired channels as DO, but how can I create the signal desired on these channels?

  Best regards

  Danny.

  Howdy Danny!

  If you try to build a train of digital pulses with a frequency cycle and specified duty then using counters shipped from the USB-6221 is certainly the way to go.  Unfortunately, as you have discovered there are only two meters of material available on the USB-6221 (Ctr0 and Ctr1).

  Fortunately, you can also use the digital output lines to efficiently create a train of pulses with a frequency cycle and specified duty.  You will need create a table of examples which, when released at the specified sampling rate, looks like a period of your waveform.  For example, if my sampling rate is 1 MHz and I want to create a square wave of 100 kHz and a cycle of operation of 20% low high/80% I would generate the following examples:

  {1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}

  Please let me know if this description is clear or if there is anything I need to explain more in detail.

  Kind regards

• Can I use a 6343 OR USB as an entry grounded to trigger an injector?

  Hello forum members

  I'd like to be able to fire a solenoid valve high speed (low impedance about 1.6 ohm) with a peak and hold the pilot injector (from AEM).  The output of the P & H driver is activated when the trigger on input is connected to the Earth.  Can I use the 6343 to provide this ground trigger?  I read somewhere in the manual that I might be able to use a PFI or DIO line as output a 0 at the wheel.  Is that what I'm looking for?

  Thanks in advance,

  -Mike

  Mike,

  On the second page of the document, he says: trigger impedance: 220 ohms, shot at 12 V input impedance ("draw" 60 my).

  IF YOU CONNECT THIS TO A LINE OF DIO, YOU MAY DAMAGE THE USB-6343!

  What you want is a driver as the series of ULN200x of ICs.  They can handle the 12 V and 60 my. Pour reversed are available as well as high logic of the DIO line will be on the ground in the entrance to the injector driver.

• Can I use the Time Capsule wireless for multiple computers without using it as a router?

  I am looking for an external backup for 2 computers drive.  I have a desktop iMac and MacBook Air.  I like the idea of being able to back up my MacBook Air wireless, but I need to make sure that it will work the way I need to.

  I already have a wireless router that works well for me, I don't need the time Capsule to act as a router. I'm just needing a wireless backup drive.  So, the question is, can I use the only time Capsule as a storage device for backup of wifi or do I also have to use it as a wifi router?  My fear is that the router service is not as good as the router, I currently have.  I live in a big House of 2 floors, making it very difficult to receive a strong signal throughout the House.

  can I use time Capsule only as a backup wireless storage device or do I also have to use it as a wifi router?

  Time Capsule need to connect to your router/modem existing using wired Ethernet wired, permanent.

  If you plan to use the time Capsule to back up your Mac with the help of the application Time Machine on every Mac, the Mac will have to save on the wireless signal Time Capsule for the process to be officially supported by Apple.

  While it is possible to turn off wireless on the Time Capsule and try to save it to your existing wireless network... and it pourrait work... but there will be no Apple support backup problems... so it would be a good idea to plan to use Time Capsule wireless backup purposes.

• Can I use time capsule as external hard drive?

  Can I use time capsule as external hard drive so that I can access a file or a specific folder by searching for its name?

  A TC is now and for always player network... no external. So there are limits to its use.

  If you are multitasking your TC with Time Machine and then using a DMG file as a virtual drive is better than directly copy files... However sharing becomes impossible. One person at a time can open the DMG.

  See pondini. T3 http://pondini.org/TM/Time_Capsule.html

  Old but still interesting to read.

  You can certainly create a folder on the TC and copy your files on it, and then perform a search. Research is slow on wireless is so the speed of transfer of large files. With the help of ethernet is certainly encouraged to desktop computers.

  Sharing folders on the TC is also now more difficult with increasing security at El Capo and OS later. You do not create on the computer records are not available. And even the ones you create can occasionally and autonomous change permissions (since the TC controls drive not the computer), you lock your own files on... I answer these questions once a week.

  Not all software on Mac supports using network drives. The most difficult is photos that can corrupt the library due to disconnections... which are the most common wireless. Be warned backups are important and not easy to do because of the slowness of the USB port on the TC and you end up really need to another location on the network for backup on.

  Generally, I advise the people not not to use the TC for direct files... That is to say, if you edit a document, make sure that it is on a local drive... When you have finished the document, you can copy it to the network drive and delete the local version. Easy for... not so easy documents for photos with major libraries.

  A TC cannot save itself and Time Machine backup impossible network drives... This means that no backup will be your files in the TC, unless you take the initiative and do it.

• I have an old Mac Mini with a DVI Port that came with a VGA DVI-adapter.  Tonight, my monitor went down.  Brand new monitor works with that?  Can I use an adapter?  If yes should which adapter I?

  I have an old Mac Mini with a DVI Port that came with a VGA DVI-adapter.  Tonight, my monitor went down.  Brand new monitor works with that? Any recommendations? Can I use an adapter?  If yes should which adapter I?

  You can use any DVI monitor DVI port directly or have any VGA monitor with the power that you adapter. A HDMI monitor might work with an adapter DVI to HDMI in a pinch, but HDMI tends to be more fickle.
