How to trigger the camera and light pulsed with PCIe-1427

Hello

We recently bought an acquisition card NI PCIe-1024 and the NI Vision Builder.

I am new to imaging applications and need support to get started.

Application:

We have a camera viewing a scene which is illuminated by a pulsed light source (e.g., a strobe).

We want to use the PCIe-1427 as the master for the outbreak of the camera and strobe light.

The first trigger (Ch 0) transmitting signals TTL to camera to 30 Hz (30 fps).

The second trigger (Ch 1) send bursts of pulses to the strobe light to e.g. 10 kHz. This trigger must only send impulses all other images, so that we can save alternating light and dark images in order to perform background subtraction.

I tried to set up the channels of the trigger and create virtual channels in the measurement and Applications Explorer, but apparently this is not possible.

Since it is an application critical time, I'd appreciate an example vi that sets up the channels two trigger and download managers in the camera to get started on this application. Thank you.

Software of NEITHER: LabVIEW version 10

Materials: Device for the Acquisition of Image (IMAQ) PCIe-1427 driver Version: NOR-IMAQ 4.4 OS: Windows 7

Thank you, Justin.

I'll copy this request to the machine Vision Group as you suggested. I looked at the link sent you me and made progress (limited). I can see on an oscilloscope trigger signals, and the camera acquires images. However, I only managed to do work for pulse trains continuous, not a shots or bursts of pulses.

No need to answer that. Thanks for your help.

  • How to record the screen and add audio with QuickTime?

    I can't wait to make my first video through QuickTime player, but I'm stuck on the following:

    (1) new screen recording - I'm able to capture the process of my video with this feature

    (2) audio new recovery - separately, I can record my audio

    But can't do the task above at the same time which means that I can save the process through and add my voice at once? Is this possible?

    Hello Vishal2014,

    I understand you are trying to create videos with recordings of screen as well as a voiceover. I can help you with that.

    Now, when you set up your registration form, you have the option to choose a microphone to talk and create video at the same time. This would reduce you adding the clip after the fact. Take a look at the first link below that will go on the way to do this.

    Save your screen
    https://help.Apple.com/QuickTimePlayerX/Mac/10.11/index.html?localePath=en.lproj #/ qtp97b08e666

    Now if you want to add audio to the video that you already created, consider using iMovie. You can import video, and during playback, you can save your audio files on top of the video. Take a look at the following article for more details on how to achieve this.

  • How to detect the relay ON / OFF state with PCI 6221 analog input card

    In order to test if a relay is ON / OFF using my card PCI 6221 DAQ devices and ports of HAVE it.  I conect of the relay contacts to an AO giving 5 v and the other contact to an AI in order to detect the corrent.  In addition to a bridge is necessary to close the circuit betweeb the AO and AI.

    Shoud this bridge conect the MASS of two ports?

    The plan is: relay - AO (5 v) - AO GND - GND AI - AI0 -.

    This does not work and gives a continuous corrent to 10 V (I think it is a saturated)

    Hint, please?

    The simplest connection is:

    • One side of the relay contact: + 5V PCI 6221

    • Other side of the relay contact: all DI PCI - 6221

    But I would add a DI (for example 10 k) resistance to GND of the PCI 6221. This will outline the entrance to GND when the relay contact is open.

  • The right way to face the camera and camera on standby?

    How one brings the camera back to life after the unit returns to standby mode?  What is the right way to manage the device sleep and wake?  Any help is appreciated.

    Hi Sucroid,

    I intend to produce a sample that shows this I hope that during the holiday season.

    Here is some information that can hopefully help you get started...

    When the screen goes to sleep, off camera equipment.  There is nothing you can do about it today, outside of the application one keep awake in your application window. (value SCREEN_PROPERTY_IDLE_MODE SCREEN_IDLE_MODE_KEEP_AWAKE).  Note that this won't save you a user who clicks the power button to force the unit in standby mode.  It will protect you against a situation where your application goes to background or another application requires video resources that are used by the camera.  In these two situations, your application will lose his viewfinder.

    But all is not lost!  There are some events of status, you can listen to that lets you know that the camera stops.  You can listen to these events either with an attached status_callback (applied when starting the viewfinder for example), or by authorizing explicitly state the events using camera_enable_status_event() and waiting for impulses of status.  All these things are detailed in the documentation for the API of photo here: http://developer.blackberry.com/native/reference/bb10/com.qnx.doc.camera.lib_ref/topic/overview.html

    The corresponding lights events are:

    CAMERA_STATUS_RESOURCENOTAVAIL - this event is logged every time that the camera is about to close.  If you have previously called camera_register_resource(), this is the event that listen to you to know that all your camera buffers are about to be démappés - so stop all logic that looks at them and then camera_deregister_resource() camm.  If you do not physically the buffers of viewfinder, then necessarily no need to use this registry/invert mechanism.  It's just there to provide warning and to activate the drivers of the device for you to recognize that it is safe to unamp wait for memory.  Each time the screen goes to sleep, the power button is pressed, or another application has need of resources of the camera, you will get this signal.  If you are curious to know the reason, you can check the 'extra' uint16_t argument in the callback of the situation for one of the camera_powerdownreason_t values.  All video recordings currently active or encodings auto-terminera when this signal is received.

    CAMERA_STATUS_POWERDOWN - event status is reported immediately after the hardware of the device is turned off.  You can't interact more with the camera until this condition is removed.  Note that to capture this event, you will need the user of the status of the event-mode (camera_enable_status_event()) interface, because any reminder of status you can have attached when starting the viewfinder will be cleaned up when the viewfinder stops.

    CAMERA_STATUS_POWERUP - event status is reported immediately after that camera material is fed up after having previously be put off.  Even not not on using status of event-mode interface (camera_enable_status_event()) applies in this case too.

    So, what can you do with this information?

    Well, tuned for CAMERA_STATUS_RESOURCENOTAVAIL will tell you when your viewfinder will close.  At this point, your application must enter a State where he is waiting for an event that will wake it again...

    In most cases, this is the event browser that indicates your application is active or foreground again (NAVIGATOR_WINDOW_ACTIVE or equivalent).

    So when your application is told by browser is it back to the foreground, you can then restart the viewfinder using camera_start_photo_viewfinder() or camera_start_video_viewfinder() according to the requirements of your application.  You will still need to follow the same recipe to start the viewfinder as a cold start your application (for example. Wait for the window of your viewfinder to be filled), but you will not need to reconfigure all the settings.

    OK... which covers 99% of the use cases that you will encounter.  Use case for the 1% remaining, you will need to follow for this CAMERA_STATUS_POWERUP event.  Why?  Well, there is a race condition when things down, in which case if the user wakes up the device while the camera is closing (eg. they struck twice in quick succession, the power button), then the camera will enter its off State, but navigator may actually not report your application it becomes idle.  This is because the infrastructure of power management is waiting actually for the material from the camera to the power off until the system goes to sleep.  If the user wakes up the device upward, then this action is canceled, and the unit enters never actually standby.  In this case of corner, navigator does not say your app to become active, again because he never told your application becomes idle.  So what are you doing?  Well, I have 2 suggestions:

    1. You can follow to CAMERA_STATUS_POWERUP using the event interface mode for the camera equipment.  It's actually the more correct approach and what we are doing internally with the BB10 camera App.
    2. You can use a timer to try to wake up the camera in the case of this corner case occurred.  for example. wait 5 seconds after the signal CAMERA_STATUS_RESOURCENOTAVAIL.  If your application has not been made inactive by browser, then you can try turning it back on the camera.

    I hope this help get you pointed in the right direction and still... I plan on collecting a best-practice appropriate sample that illustrates exactly how to do this when the weather!

    See you soon,.

  • How to trigger the dictation from the smart keyboard on the iPad pro.

    I use dictated on my iPhone and my iPad quite often.

    I don't see how to get the soft keyboard back to press the button of the microphone are there, such space suggested by some on this forum.

    This doesn't seem to work in the latest iOS Update 9.

    I would be fine with a hotkey, or have to invoke the keyboard of the shop, then press the button of the microphone, but I don't see how do either.

    When the Emoji button on the keyboard smart strike as the keyboard, the software keyboard emoji is displayed, the space but when I press the soft ABC capital but I cannot get to the regular keyboard with the microphone button.

    A possible alternative would be to use Siri to dictation trigger in recording a memo or another application, space but I didn't understand how to do this job either.
