examples of LabVIEW ARM code

Hello

I am new to Labview ARM I used an ek-lm3s8962 Keil Committee.

I would like to know if there are a few tutorials and code examples on communications with devices:

How to write you SD card?

How to use CAN, SPI, I2C and UART?

How to use the OLED?

Is it possible to use the FIFO memory with labview ARM and how?

Is it possible to target the daughterboard with Labview, this Board includes a processor LM3S2110?

How communicate between a time critical Vi which runs on the ARM processor and not time critical Vi host that runs on the PC?

Thank you very much.

Your Neil

Hi Neil,

How to write you SD card?

The SD card slot only is not currently supported in point 1.1 of the ARM.  The next version of the ARM should support this device.  Once this is the case, you can access the SD card using the primitives of e/s files.

How to use CAN, SPI, I2C and UART?

I found an example of UART in the Finder for example OR in Modules and Toolkits > ARM > Luminary Micro > protocol drivers > Comm.lvproj series.  I will attach also a project that uses CAN communicate with the LMS2110.  As for I2C/SPI, I suggest experimenting with the screws for this (located on the ARM > palette SPI and I2C) and consultation of the other threads on the use of these screws or create another thread.

How to use the OLED?

There is an example of this in the Finder for example OR in Modules and Toolkits > ARM > Luminary Micro > Device Drivers > OLED.lvproj.

Is it possible to use the FIFO memory with labview ARM and how?

FIFO on ARM is very similar to the desktop.  These screws are located in the data Communication > synchronization > FIFO pallet in real time.  There are several examples on how to use these FIFO on ni.com.

Is it possible to target the daughterboard with Labview, this Board includes a processor LM3S2110?

You can provide this Commission with CAN, as shown in the attached draft.

How communicate between a time critical Vi which runs on the ARM processor and not time critical Vi host that runs on the PC?

See the related example. RT FIFO If you use the FIFO screws I mentioned above, you should be able to do something similar.  I suspect that the FIFO is used to communicate between a critical time timed loop and while loop a criticism.  The while loop would then use TCP/series (or even shared network variables) to communicate to the host.

Good luck

    Hola,

    UNA opcion pudiese ser as el VI tenga activated than el los objetos cambie change el tamano del vi al tamano y you tengas una resolución por lo than todos menos themselves together. Pero por lo than veo los controls como tal estan well, what tienes diferente is the text, eso deberse a that the Application defined en fuente you can computador large sea mas del computador donde is programo originalmente el VI, prueba el text seleccionando y colocando una fuente mas pequeña.

  • LabVIEW arm pwm

    Hi all

    I'm trying to generate PWM with Laminary LM3S8962 signals.

    At first, I thought that always the entrance of the PWM output is the ratio between the width of the pulses.

    I connected to AI0 PWM2 and run this VI:

    By changing the value "PWM Input" AI0 strangely varies

    Hi Neil84,

    Thanks for posting on the Forum of National Instruments.

    Just to add some information about PWM with LabVIEW Embedded for ARM. Set you the divider in the properties of elementary school of e/s of the project? Here is some information pulled using LabVIEW:

    «The PWM frequency is the inverse of the period PWM.» A 16-bit system clock divider controls the frequency. For example, if the system clock is 50 MHz, the lowest possible PWM frequency is about 760 Hz. If you need a lower frequency, predivide based on the system clock of time PWM. To change the predivider, click the basic I/o node in the Project Explorer window, and then select Properties. This property affects the dating: 0/1, 2/3, 4/5. For example, if you set the output frequency 4, you also set the output frequency 5 because the two outputs share a common time base. "

    Thus, with a 50 MHz clock and a 16 - bit divider, you would get 50 MHz/2 ^ 16 = 762, and therefore the lowest frequency you can achieve (using the value of the divisor of 64) would be around 12 Hz. You set this value of divisor of the project for the e/s specific PWM.

    Let me know if this clears up things or if you have additional questions.

    Kind regards

  • LabVIEW ARM embedded systems tutorial

    Nice day

    I started working on a project using the Development Council LM3S8962 to initially work lencuaje C, is very economical and in some cases, better than the Arduino

    but I see that you can also work with Labview, if anyone has worked on this and can give me some feedback would be very happy

    Hi Tom,

    If you have questions about the material/pine itself, I would consult for this piece of hardware user's guide. For example, here: http://chess.eecs.berkeley.edu/eecs149/sp09/docs/EK-LM3S8962_EvalBoard_UM.pdf

    The software/hardware connection is usually quite simple. For example, if you create a point basic IO and select PWM0, then everything that you send to this node will go to the PIN marked on your map as PWM0. In addition, there are a number of properties in the software that you can configure in the software for the PWM output: http://zone.ni.com/reference/en-XX/help/372459E-01/lvarmhelp/arm_eio_prop_pwm/

    If you have specific questions or specific things that do not work, I am able to help you, but I think it's all general support material we have.

  • USB-6501 - impossible to find a basic example of Labview

    Hello

    I recently bought a USB-6501 card and I used it in my own succesfully end and C++ programs using the DAQmx drivers.

    Then I tried to move to Labview 2009 (I never used Labview) so I looked for a simple example.

    I tried to boot from the example 'interactive Control Panel' (http://digital.ni.com/public.nsf/allkb/AF0F31EE5D2AD23F862573140009D7C2?OpenDocument).

    I had to install the 'DAQmx Base' for him to start, as described in the previous link. now it begins (before Labview attempted to get a few missing .vi) but I get a message "error 200220 occurred at an unidentified locatio.

    Then I realized this example is 'old' (as explained here: http://forums.ni.com/ni/board/message?board.id=170&thread.id=209247), and it is suggested to look for a new one in example Finder ' entry-level equipment / output-> DAQmx-> Digital measurement (or generation)-> read Dig Port.VI.

    I tried, but along the way ' entry-level equipment / output-> DAQmx-> "only a folder named"Analog Measurement\Voltage"exists.

    Also in the search for 'Reading dig Port.VI' does not work.

    I've already spent many hours in this research and tent and the fact that I am not able to find not even a basic example, it is quite frustrating and it is making me give up the idea of using Labview.

    Please can anyone give me any suggestions where find/download an example simple and minimum to use my USB6501 in Labview 2009?

    Thank you

    Scipione.

    First, install DAQmx Base was a mistake. Uninstall it and then install the Driver-OR-DAQmx. The driver must be installed after the installation of LabVIEW. After installation, make sure that the device is listed in MAX under "DAQmx devices. If it is not, your installation is still not correct.

    To search for example LabVIEW, see help > find examples. Under Input and Output hardware > DAQmx, you will find the digital generation and numerical measures. You have to look at the simple, timed software examples such as read write dig Chan, writing Port to dig, dig chan, reading Dig Port. You also have the option to use the DAQ Assistant.

  • Freescale in the LabVIEW ARM controller?

    Hi all

    Is it possible to use the freescale MC9S12XEP100RMV controller in the ARMS of LabVIEW?

    Thanks and greetings

    Hi Suren,

    The LabVIEW Embedded Module for ARM Microcontrollers using the "Keil uVision development toolchain to compile, download and debug applications", as this article explains.  (Taken peripheral ARM supported by LabVIEW)

    With this in mind, you should be able to use any microcontroller that supports the "RL-ARM real-time library."  Keil device database lists microcontrollers currently supported with this library.  (RL-ARM real-time library)

    The Freescale MC9S12XEP100RMV MCU is not listed as being supported.  Knowing this, you will not be able to use the LabVIEW Embedded Module for ARM, but you can use the LabVIEW Microprocessor SDK of Module.  The only difference is that the ARM Module has been built on the Module SDK.  The Module SDK is more "generic" and allows to develop support for virtually any 32-bit microcontroller software.

    I hope this helps.

  • LabVIEW FPGA code changes

    Hello

    I'm working on 802.11 application, I tried to change the FPGA code.

    I really need to compile all the code after changes? or just save the VI to observe the effects of the change.

    Yes, LabVIEW code must be compiled using the FPGA Toolbox after you make all the changes. I think the only exception is when you run mode simulated on your PC.

    Do you know what your baud rate? You can use the BTR values to program the SJA1000 with the settings real bit rate baud. The current formula should be the online help.

  • LabVIEW C code

    I was wondering if there is any means possible to convert my LabVIEW VI (build with call loops and its case) in a C code based, or anything like that which are closely related to the C code. The reason is that most of our measuring instruments are controlled with C code base and we must integrate labview c.

  • Resource not found. -LabVIEW error code load 3

    LV2011 XP SP3

    I created an executable of LabVIEW by using a party lvlib 3rd screws (the screws in this lvlib are only stdcall (WINAPI) CLFs.)

    After you have installed the RTE of LV 2011 on the target computer, I copied the .exe and the necessary support files. When I try to run the executable, I get the following errors for each VI used from the 3rd party lvlib:

    LabVIEW: Resource not found.
    Error loading VI 'thirdParty.lvlib:any.vi '. LabVIEW support 3 error code: could not load façade.

    This 3rd party lvlib is included in the application under dependencies Builder. In addition, none of the screws to have their facades open. (They have the appearance of the default window properties). I also installed the thirdParty.lvlib on the computer target in the same directory structure that the Application Builder uses. (It is interesting that the DLL is taking in charge the CLFs in part 3 lvlib live)

    Any thoughts?

    Screws serving as the library would automatically be included in the executable, so there's no need to install the library on the target computer. It seems to me that you have a missing dependency for the DLL. Perhaps, the DLL requires another DLL? Where is placed the DLL?
