16 bit CRC IBM

Hello

I'm new to CRC calculation and currently having difficulties to find the Labview live that I can use for the calculation.  I was able to find and use a calculator online CRC to generate correct values, however I could not find any Labview VI that generates values that correspond to the online calculator. See the link: http://www.lammertbies.nl/comm/info/crc-calculation.html

I am using CRC-16-IBM. I found a VI that seems applicable, but I don't know how to use it.  All my attempts here to a CRC calculation with the vi has failed. Perhaps, it is not the good vi or I'm doing something wrong.   Please try to see if you can use the VI and generate corresponding values with the on-line calculator of the CRC. See attachment.

Thank you

I had to do some research to figure out what was the real polynomial (actually lied here).  But then looking at the code, I came up with this.  Certainly, the lookup table will be faster because many of these calculations are predone.

  • 8-bit CRC-CCITT

    Hello

    I'm trying to generate a bit 8 CCITT CRC with the polynomal 9-bit U3 + U2 + U4 + U8 + 1

    I have studied and tried to change the CRC 16 bit found here calculator and Vi post by Shoneill here, but I'm getting nowhere...

    Generator of CRC should be initialized to 0, LSB is sent first.

    In the datasheet, I found the example:

    Data 1:1010 0000

    2 data: 0000 0011

    CRC: 0010 1010

    Any intervention on how I can modify the existing 16-bit calcultors, or would it be a better idea to start from scratch?

    Solved. Change the shoneill vi finally gave me the result I needed.

  • Get the error access denied when you try to install Windows 7-64 bit Okidata IBM-ML321 of windows update. Error reported in the newspaper like 80070005

    Hi David,

    I suggest you scan the computer antivirus using the Microsoft Safety Scanner.

    Microsoft safety scanner will help us to get rid of software viruses, spyware and other malicious software.

    The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.

    http://www.Microsoft.com/security/scanner/en-us/default.aspx

    Note:

    1) the Microsoft Safety Scanner expires 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

    2) if you run the virus scan of the program which is infected with the virus will be deleted. Therefore, reinstall the program. Also, if files and folders are affected by the virus, while they might even get deleted.

    Hope this information helps. Answer the post with an up-to-date issue report to help you further.

  • I2C/SMBus Melexis MLX90614 IR Termometr

    I use the interface NOR-8451 read the temperature of the thermometer IR Melexis, who use the SMBus Protocol.
    Use the I2C mode I can read RAM for display of the actual temperature, but can not cooperate with EEPROM. Has no made communication with thermometer?
    There are some specific behaviors: infrared device respond to each address, but there is no result for the address change I2C/SMBus (sholud) command.
    I did all the sugested (such as disconnection/reconnection) shares and still have the view to each address.

    In fact I need three or four devices to one bus and this is the reason why I'm looking for solutions.

    Ok. I see 4 errors in your code

    1. on your Read_Termometer_NI_send.vi, you are only reading 2 bytes on reading when it appears that the Melexis returns 3 bytes (data Low, High Data, PEC).

    2. you do a left shift on the I2C_Termom_Addr of 1. Our API uses a 7-bit address. With the default address of 0, it is well, but when you change the address it will no longer work.

    3. on your writing, you split the request in the multiple Scriptures (writing (command), writing (given Low, High Data, PEC)). This will create the incorrect model on the bus. You must use a single entry with 4-byte. Also, I don't know if reading will do nothing good. You should probably always do a read/write. Again, he would do a reading of 3 and an EEPROM_SMBus_Address to read again just writing.

    4. you get a zero for the PEC. I think it must be correct 8-bit CRC on the first three items (command, Dala Low, High Data) or else command is likely to be rejected by your device.

  • computer 37 can laptop XP continues to tell me memory online someone please advise me as to what I should do? Thank you very much.

    'Hi' and thanks for taking your time in this matter. I have a 32-bit xp (IBM). He started to give me a message not enough memory on line 37 and now I get messages saying: it seeks to increase storage space. My xp freezes and I don't always get the messages that responded to the questionnaire. If you could help me please I would be very happy. Thank you for your time.

    out of memory in any line is generally a problem of Web page

    but, you can assign the system managed pagefile, so Windows will have enough memory to do what he must do.

    go to start, right click on my computer and choose Properties

    Advanced performance, settings tab, Advanced tab, choose virtual memory, click on change

    put check into touch for the managed system, success TOGETHER, right out and then reboot the pc.

  • Create the circuit of the STS - V between 2 15454 SONET with CE100T

    Hi all

    I have a problem that I can't find documentation for.

    I create an ethernet point to point circuit between 2 15454 SONET with CLC ver 8.5 knots.  The circuit will carry you a VLAN not routed between switches, Cisco 4948 in 2 data centers.  I use CE100T-8 cards which the ethernet 100/full value, checked the Frother.  The POS is configured with a GFP - F frame and 32-bit CRC.  Type of circuit is a single STS - V STS to 50Mbit of bandwidth.

    The switch ports are configured as access ports on the VIRTUAL LAN set to 100/full.  At the end of B, the connection between the switch and the port of THIS is a straight through cable.  End is a crossover.  switch ports are configured as such:

    switchport access vlan 512

    switchport mode access

    switchport nonegotiate

    Speed 100

    full duplex

    Problem I have is that end A "Transport Layer failure" alarm to end and end B has the 'Carrier loss on the LAN' alarm near end.  No end shows an ethernet connection

    Wiring has been tested, I've tried other ports on the CE and have deleted and recreated the circuit board.

    What simple step/setting I'm missing?

    Thank you in advance,

    Jim Bowen

    [email protected] / * /.

    Jim,

    It seems that your problem is by your side B that has the loss of carrier on the LAN. The failure of Transport layer will be on the end node in these cases.

    You mentioned that the end B is a straight through cable from the switch to the CE card but the side is cross. The first thing you can try is to put a cable on the side B as well because it looks like the side of A working very well (doesn't have the loss of carrier on LAN).

    I don't remember if cards of IT have an option to hardcode the speed and duplex but if they can only so if the suggestion of cable does not work. If this does not work, you can try setting autonegotiation on switch and the map of THIS to see if it solves your problem. Once the loss of the carrier and LAN to clear alarm you should be up and running.

    Also, I can't remember if the EC supports the loopback test, but if you can try try to put a Terminal loop on the B side (it's optical to) your end should appear and your switch should appear/maximum looping. I would like to know how things work out for you. Looks like you're almost there a few tweaks should get running.

    Thank you.

  • Limit of Maxextent reaching index Segment

    Hello


    I am facing a problem with Index segment limit maxextents.

    The EXTENSIONS MAX_EXTENTS columns and in the DBA_SEGMENTS for this Segment of the Index is 1.

    I tried to increase this size maxextents for this segment, but I get this error message.

    ALTER index... storage (maxextents 5)

    ERROR on line 1:

    I found that the Tablespace containing this segment is managed dictionary.

    Is this problem because of the storage space managed dictionary?

    How to solve this problem?

    What is an index organized table?
    If so you can't change the definition of the storage of the index - you need to do this on the table associated with the altar storage (...) syntax table.
