FTDI interfacing with myRIO RT Linux


Hi fahad80,

1.) make sure you have installing NI VISA USB Passport on the myRIO (I realized I had not checked it in the picture)

2.) go from MAX, right-click on the myRIO under systems remote and select "transfer files".

Then, go to:

usr/local/vxipnp/linux/NIvisa /.

Open the visaconf.ini file and add the following tokens [ASRL-RSRC-ALIAS] section:

Name3 = "ASRL4::INSTR."

Enabled3 = 1

Static3 = 1

SystemName3 = "/ dev/ttyUSB0 '.

BaudRate3 = 9600

Parity3 = 0

StopBits3 = 10

DataBits3 = 8

FlowCtrl3 = 0

NumOfResources = 4

3.) then restart the device and use PuTTY SSH in the myRIO

4.) then we will have to use this command in Terminal:

chmod o + rw ttyUSB0

5.) MAX refresh/restart to check if the serial port is displayed and is able to communicate and if not, try to restart the myRIO

I would like to know what are the results of that.

Kind regards

  • Encoder interfaced with NOR-9401

    I bought a coder who has open collector and resistance to pull-up 3.3 kohm (TTL) logic output.

    The encoder comes with four sons: power + 5V, GND, channel A and channel B. channel A and B are logic output.

    Channel A and B are connected to the OID of NOR-9401 which is mounted on the cRIO.

    A standard VI for encoder counting is used and compiled under the FPGA environment.

    During the measurement, I have observed that there are number of significant loss in both directions encoder.

    I don't think that there is a problem with VI like I used it several times on the encoders with output RS422.

    Is there a problem with my current encoder with respect to its electrical interface with NOR-9401?

    Thank you.

    I don't think that there is a problem with pull-up resistance. Even if the digital IO ports have their own resistance to pull-up (usually of the order of 4.7kOhm - should be included in the manual), the power to be handled by the circuit of encoder output transistor is about 2mA. -Check your configuration for a correct connection GND. You must connect the encoder directly power GND to DGND to the printed circuit board Terminal.

  • frequency corresponding problem with myrio!

    Currently, I am working with myRIO and Labview 2013 to generate sinusoidal PWM signals.
    When I created 'analogue output' tab myRio and connected to the Oscilloscope, oscilloscope waveform could not show me the appropriate frequency combined with a frequency that I gave in labiew. Is there a relationship between the frequency of "the"(myRio tap) of analog input between real-time rate? ". Otherwise, is it certainly possible to calibrate the frequency in labview?

  • Interfacing with several unknown USB devices; all producing NMEA strings

    Hi all

    Question about the peripheral USB interface and their associated drivers.

    I have the obligation to build an application that interacts with the USB devices that produce NMEA strings. I have the library to parse NMEA strings, but I fight with interfacing with several unknown USB devices. When deploying applications, I know not all possible USB devices to use.

    Is it possible to produce one driver who will accept any USB device strings?

    Or, more likely, is there a way to get the LV to recognize a connected USB device and automatically find / install the driver like windows does and is it possible to do in a deployed application?

    I had a trawl of the forums, but I've not found anything that specific.

    Thanks, I really appreciate the help.

    About the VI "set up the serial port", my problem is that the choice of COM port is in a separate menu (not directly related to the VI) and it allows all possible COM ports to be selected. That can be addressed.

    I am not expecting an all-in-one solution but asked the question in case it was possible.

    What I realized, is that for my specific condition to read strings from a USB device. It is likely to be sent over a serial connection. LV can handle this well and easily assuming the device has the installed driver / settings are available.

    LV (and indeed any other program) will not work without a device driver / settings. In this case, parameters set must be found (error) / a USB RAW driver would need to be developed. Devices requirng a RAW USB driver would need a serious review to continue due to the time and effort required. All this effort is work inherited from the AIDS to navigation

    I appreciate any help and I think I got the answer I was looking for! Thank you very much

  • A module C - DAQ exists which will interface with standard RV - C?

    Module C - DAQ exists that if interface with standard RV - C (vehicles recreational CAN)? RV - C seems to be a variant of J1939 according to Wikipedia.

    I would use 9861 OR or NI 9862. I'm new on CAN protocol and evaluate some assistance.

    I've never used RV - can, but according to Wikipedia, the rate is 250Kbaud, so you'll want high speed CAN peripheral, 9862, you can set baud rate on init of the material.  After installing XNet and cDAQ software, you have a max bus monitor and several examples in the example Finder to read and write raw images.  After that, you'll want to read on the standard to understand how to format and analyze the data.

    Also if you have any questions, you can post on the Sub-forum Auto , they can probably answer more specific questions.

  • I use pci-6221, I need her to interface with thermocouple with voltage up to 5v

    I use as my pci-6221 or data acquisition card and card 8.2.this labview version gives the constant 10.5 volt signal in at the entrance to analog channel AO on pin 68 and 34. why it shows 10.5 although I did not connect any input.i use type k thermocouple and after signal conditioning with tl0804 I need it interface with AI 0.i channel unaware aware of off the road on the output pins this Card.i need to operate an electric rod that needs 24 volt DC.i give entry to the pins HAVE with variable dc power block after reaching the limit I set(eg:2v) it jumps instantly to 10.5 volts.

    You have your task to acquisition of data configured for the mode differential or asymmetric acquisition for the analog input?

    I don't understand your comment about to connect the pins WITH a DC power supply.  Why is that you connect a DC power supply to the analog input?

    Using an analog output or digital output to operate the electric rod?  I'll assume that you are looking for on/off control.  A digital output is not the voltage or current to drive something that big.  You may be able to find a relay for coil 5VDC.  Check current requirements.  With which you can have the relay to connect or disconnect a power supply of 24 VDC is the actuator.  Make sure you have a protection diode across the relay coil wired, so that the magnetic field of the coil does not damage the analog output of your card.

    Another possibility is to have the 5 VDC output transistor circuit switches the 24 VDC circuit.

    Hi thonson35,

    ·         Have you made changes on the computer before this problem?

    ·         You get the error message?

    ·         Do you have any human Interface device attached to the computer which does not (such as the keyboard, mouse and joysticks)?

    I suggest you to uninstall and reinstall all devices interface. Follow these steps:

    1. Click Start, type device Search Manager and press to enter.

    2. Device Manager window opens, expand Interface devices.

    3 right-click every device under the peripheral Interface node and then click on uninstall to remove them one at a time.

    4 restart your computer, windows will reinstall the Human Interface Devices.

    5. perform a test to ensure that the problem is solved.

  • IP IVR interfacing with SAP

    We are about to implement the Cisco IP IVR linking to our AS / 400. We have it with our current IVR, so it's easy. In a few months, we operate off the coast of the AS400 to an implementation of SAP for inventory and accounts of users and all this other nonsense. Someone has interfaced with success the IVR and SAP to let me know if this is possible?

    I guess you have to go through third-party programs, such as Java and VXML. We have a customer who use Java with Websphere measures.

  • Are there ways to OBIEE interface with client application?

    Our OBIEE 10.3.4 on Redhat, OBIEE version to connect to an Oracle Database 11.2.0.2 running on the same box of Redhat like OBIEE. Our application is based on java web application you use Tomcat, he point to the OLTP of Oracle Database 11.2.0.2 on a dedicated server from Redhat.

    One of the requirements for the original application was logical with complecated OLTP data process and create reports in text files. The customer wants now OBI allows you to view, print, and distribute reports. The best way to meet this requirement of change to the advanced stage of development seem to interface with OBIEE application, if at all possible. In this way, by clicking on a button in the GUI of the application, a stream of formatted data is sent to the OBI Stardoll service in response to a request. A client OBI page will then be displayed to shpw reports and allow users to print and distribute.

    Now there is some OBI API that allows an application to call to interface with OBIEE?

    Thank you.

  • Documentation on creating user interface (with Javascript and / or Flash)

    Hello

    so far I use JavaScript to create my own UI, something like

    funky var = new window ("dialog", "window title ', [100,100,300,200]");
    DWIN.okButton = Dwin.add ('button', [150,70,190,90], 'OK', {name: 'ok'});
    DWIN.myText = Dwin.add ('edittext', [10,10,190,30], ' mytext' ");

    ... and so on.

    I've put together some of the pieces on the use of this 'New Window()' thing here and there, but what Miss me is something like official documentation on these orders. The official Adobe documentation does not include this information, so where can I find it?

    Moreover, I am looking for information on the generation of the user interface with Flash, but aside from one (fairly complex) example that is in the folder "Sample Scripts" of my installation, I couldn't find anything.

    So, where can I get this information? I use CS5 on Windows 7 (64-bit)
