• Acquisition of images with 3 USB cameras causing too many uses of the memory/cpu

  Dear experts,

  I'm trying to capture images with 3 cameras USB, located in 3 different positions. I have to initialize each cameras using USB list vi camera when switching between cameras. I realize that, by making this method causing too many uses of the memory/cpu and can cause CPU hang up. If I stop the program, the memory/cpu counter are down.

  Do you know how to reduce this problem.

  Thank you

• cRIO 9067 to hired 7fh USB RS232

  Hello

  I have a cRIO 9067 and would like to interface with an instrument that has a converter USB-RS232 from SiLabs.  I can't comminicate with this instrument easily on a Windows PC.  I am able to see the device in MAX when its the cRIO connection.  IT appears under "Devices and Interfaces" as "USB0::0x1FB9:0 x 0100: 121A00A:RAW ' with model number and description of the device.

  I followed the description at this link, but I don't get a ttyUSB # devices.

  https://decibel.NI.com/content/docs/doc-34827

  Is it possible to get this working on the cRIO as a serial port?

  Thank you.

  After some research, talk with people, NOR google and to talk with people to lakeshore.com (provider of the device) this is what I have reconstitute on how to make this work:

  • Under Linux, usb devices are listed automatically, and by default, will appear as a USB RAW device
  
  
  • Once the USB device has been identified, it can then subsequently be linked to a driver
  
  
  • Linux determines if and when to link each device USB-based device Vendor ID (VID) and the model identifier (MID). It is usually 3-4 digit hex string.
  
  
  • In the case of the Lakeshore 121 power source, VID = MID 1FB9 = 100.       I could see in MAX for the Raw Device USB.
  
  
  • There are two levels of USB-serial device drivers. The first pilot: usbserial.ko is a generic driver that handles all USB-serial devices. This should be loaded for any USB-serial converter.
  
  
  • The second driver is specific to the chipset for the USB-serial device.       For the cRIO, there are three options which are pre-installed (DFT, 7fh and a few others)
  
  
  • The drivers can be found at /lib/modules/3.2.35-rt52-2.0.0f0/kernel/drivers/usb/serial/ (where the kernel version directory may vary)
  
  
  • Lakeshore 121 uses the TR labs CP210x chipset, so we chose this one.
  
  
  • Records of the device first of all need to be loaded by Linux. Linux can automatically do this by adding files of length zero in the module.autoload.d directory. To do this run the following:
  
  
  • CD /etc/modules.autoload.d
  
  
  • Touch usbserial
  
  
  • Touch cp210x
  
  
  • restart cRIO
  
  
  • run dmseg. grep usbserial to confirm that usbserial driver is responsible
  
  
  • run the dmesg | grep cp201x to confirm that the driver for cp210x is loaded
  
  
  • The next step is to associate the cp210x of our device USB device driver. Don't forget that linux associate unit to a pilot from the VID and moy. anyone installed linux cRIO base, I'm sure, knew nothing of the VID 121 Lakeshore and MID.
  
  
  • Lakeshore recommended to read the source code for cp210x, adding the VID and MID to the list of recognized devices, recompile the cp210x.ko file and install it on the cRIO. It would work, but it is beyond my current Linux capacity.
  
  
  • Linux offers the possibility to dynamically add MID, VID, so that a device can be recognized on the fly
  
  
  • When the driver CP210x is loaded, a struchture of the entire directory is created. There is a file because the directory structure called new_id where you can dynamically added VID, mid
  
  
  • Create a startup script to run the following command. Be aware of the problems of termination of cr/lf line between operating systems. It is generally easier to create the script on the cRIO with the VI editor to avoid any problems.
  
  
  • echo 1FB9 100 > / sys/bus/usb-serial/drivers/cp210x/new_id
  
  
  • Startup script Info: https://decibel.ni.com/content/docs/DOC-38960
  
  
  • Now, restart (or running the script), you will get a device/dev/ttyUSB [0-9]
  
  
  • Unfortunately, the creation of default of the unit ttyUSB [0-9] does not permission to write, so we have need create a UDEV rule to automatically grant writing
  
  
  • Add the following lines of code udef.conf in the folder/etc/udev

  #typical devices

  ttyUSB [0-9] * root: ATS 666

  • Create a file named 99 - ttyUSB.rules in the /etc/udev/rules.d folder
  
  
  • Add this line of code in this file:

  KERNEL == "ttyUSB [0-9]" * ", OWNER ="admin", MODE ="0666""

  • Restart the cRIO. This should be it! It worked for me.

• I want cRIO to start and stop the acquisition by push physical button on the cRIO, is this possible?

  When you use my cRIO 9024 on the ground, I prefer to be able to start and stop the acquisition with pressing a physical button on cRIO.

  I want to say I don't want it to be "as a start-up," I don't want cRIO to start the acquisition as soon as the power supply is ensured.

  Is this possible?

  Hi Cashany,

  you will surely find this switch status. But there are easier ways (but more expensive) for a button. Fiddling with a pen or a small screwdriver to switch USER1 is not what I call "user friendly"...

  -You have at least 2 voltage inputs on your module available. Use a switch voltage on the power inputs. Use a 'real' button!

  -You have an available serial port. You can set some pins on GND or voltage and check their status inside the cRIO/RT target...

• What is the importance of buffers in the Acquisition of images

  I think the question is explicit. I select the function set up IMAQ1394. It includes a command to define the number of buffers, usually they implements buffer is more than a video acquisition and 1 in the acquisition of images (I quote examples). but when I change these examples by removing the wire of the buffer total still image is acquired very well. This prompted me to ask the importance or the importance of buffers in the acquisition of images.

  Hello Asad,

  If you look at the detail help, the buffer for a setting configures VI is defined as follows:

  Number of buffers For a first acquisition, this parameter specifies the number of images to acquire. For a continuous acquisition, this parameter specifies the number of buffers that the driver uses internally.

  By default it is on, so you will always be able to acquire without specifying this entry.  For a first purchase, you will acquire the number of frames specified.  The display of the images, if you have a poster of the last image.  For a continuous acquisition, the number of buffers is defining the size of the buffer by using your pliers is.  So, if you set a buffer of size 1 rather than say 10, you have more chance to run through the buffer overflows.

  I hope this helps.

• Remote usb mouse freezes for bout 45 seconds after coming out of sleep mode

  Remote usb mouse freezes for bout 45 seconds after coming out of sleep mode

  Hi Aubrey,

  Step 1: Put the computer to boot and see if the problem still occurs

  Follow step 1 in the link below,

  How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

  http://support.Microsoft.com/kb/929135

  If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.

  Continue with the remaining steps to pin-point on the third party service.

  After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

  Important: n ' forget not the computer to start normal follow step 7 in the link.

• Please help me? Install printer Canon Image class MF5750 (USB)

  Can someone help me solve this problem:

  My laptop is HP running on Windows 7. I am trying to use my printer Canon Image class MF5750 (USB)

  I installed the driver: MF5730_5750_MFDrivers_Win_x64_us_EN_7 from the Canon website.

  However, after that I installed the drivers, my computer recognizes that the scanner and not the printer. I'm a newbie to this!  What have I done wrong or left out?

  All to first uninstall this driver from the computer and restart. Then download and install the driver appropriate for your system, if you have a 64-bit or 32-bit system?

  Do not connect the appliance until the program tell you to do.

• Support for LabVIEW 2014 and CanOPEN cRIO-9067

  Hello

  We have NEITHER 9881 CANOpen communication module and cRIO-9067.

  According to the NI 9881 product description page the module should work with cRIO-9067. However, does not support the latest NOR-Industrial Communications for CANopen 1.0.3 2014 LabVIEW and NI RIO 14.0. This means that we cannot use cRIO-9067, can we? If so, when the next version of the pilot will be available? It will work with the cRIO-9030?

  Thank you in advance,

  Nikita.

  Hi Nikita,

  I wanted to let you know that support for the cRIO-9067 is available: http://www.ni.com/download/ni-industrial-communications-for-canopen-14.5/5234/en/

• install software failures on cRIO 9067

  OK, I got a new cRIO 9067 and I noticed, while installing software on it well as MAX, everything works as long as I CHOOSE NEITHER WATCHDOG 14.0.0.  If I do, I get the following error. It's very repetitive.

  

  This is another so that I installed, otherwise:

  

  Hi Mark,

  The driver OR Watchdog is part of LabVIEW Real-time, sounds like something might be wrong with your installation of the Module LabVIEW Real-time on your computer.

  Can you uninstall and reinstall the Module LabVIEW Real-time and see if that fixes the problem?

• Same code compiled for the cRIO-9074, but reports no diagram component calendar violation for cRIO-9067

  Hi, just got my new cRIO-9067. I have converted my project over the cRIO-9067 since the cRIO 9074. Same layout module, same engine, same scan code custom fpga, (hybrid mode).  I have no problem of compilation for the 9074, which is a lower performance FPGA architecting the 9067 FPGA.

  The final timetable for windows compilation shows that the timing is respected for all clocks - 40, 80 and 120 MHz (I use a clock derived for some code sctl). During the end of compilation, during the phase of gen bitfile, I get the dreaded time violation. Investigation of the breach indicates that it is not the custom code, it is not schema components. One of them seems to be linked to the card series OR 9870 I in the chassis.

  Why? Is there anything I can try with the compiler directives for this problem? You would think that it would be easier to compile for the highest performance FPGAS...

  OK, don't ask me how I thought this output - to run I changed nothing else than this: feed the I/O node a reference FPGA of e/s instead of configure the node via the menu "link to. It makes no sense, but the compilation succeeded when I did this.

  I know it is because I created a very simple test VI in my project and made sure it does not compile without it.

• Absent from most of the NI Vision Acquisition (Acquisition of images)

  
  

  Hey, Navid,.

  This is Alex from National Instruments. IMAQ specified version is not compatible with LV 2009 and I think that's the reason for which you are not able to access the functions. Click on the following link for a chart of compatibillity for IMAQ/IMAQdx pilots:
  Compatibility table

  I recommend you only install the latest version of the software for Acquisition of Vision OR which comes with the last 4.5 IMAQ compatible with LV 2009.

• Acquisition of images using PCI-1426 and Camera Link Camera

  Hello

  I am writing a program to capture images of a Camera Link camera via the PCI 1426 acquisition card in LabVIEW. The problem that I am facing is that I am unable to find the correct controls in the functions palette to start the image capture. Could someone tell me please how much control I'm supposed to use?

  I've worked on similar request sometimes back, I used IEEE 1394 camera, so once I found the correct block diagram controls I should be able to go from there.

  Thanks in advance,

  Sandeep

  Hello Kristen,

  Thanks for the suggestion. I was able to solve this problem. I think that was what was causing the problem I have LabVIEW 8.6 installed on my system and he had the Vision Acquisition System (VAS) 8.5.1. But, once I installed VAS 8.6 I saw the IMAQ in the functions palette.

  I'm guessing that LabVIEW 8.6 does not recognize the toolboxes of previous versions.
