CRC-CCITT I guess

• 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.

• Calculation of the CRC-16 CCITT

  I need help for generating a CRC - 16 CCITT.  I've searched high and low and can't find the right one.  Here is a list of the sites that I have used to try to find a LabVIEW VI to do the trick:

  Some of these even have several CRC to the choice.

  Now, what I have is a piece of code C.  And this is where I ask for help because I have no idea how to turn C in G.  And I'm certainly not fair why this CRC is different from 'standard' ones found in the links above.

  I have attached the PDF with the code.

  Here are a few hexadecimal strings and their corresponding CRC:

  String: 00 CRC 08:07 1

  String: 00 09 CRC: 1-06

  Chain: 02 22 03 E8 CRC: E5 6a

  Chain: 02 27 03 E8 CRC: B5 CF

  Chain: 02 29 00 02 CRC: EB 57

  String: 04 29 00 01 00 03 CRC: CC 94

  Chain: 02 00 64 CRC 3D: 05 38

  If there is someone out there willing to give a shot of this I am CERTAINLY happy!

  Paul.

  Ah.  There is a small tweak in there that makes it different from the 'standard' CRC  How sneaky of them.  This code gives me the results you're looking for.

  

• Hex String CRC with different polynomial equation

  Hello

  I can't change a standard CRC16 (I guess) code for working with the equations I.

  The camera I use has the equation of x 16 + x 13 + x 12 + x 11 + x 10 + x 8 + x 6 + x 5 + x 2 + 1, with an initial value of 0.

  I tried to read about CRC via wikipedia etc, but I don't follow it now.

  I watched a lot of examples, but to be honest, I don't know why it is calculated as it is.

  Thank you.

  Here's an example, I was looking at: https://decibel.ni.com/content/docs/DOC-11072

  This code works in both cases.  But not the first.  You type something?

  

• CRC of the MBR or UEFI boot loader changes at each reboot?

  I have a Fujitsu Esprimo desktop running Windows 7 Professional.  Whenever I restart, it stops before loading Windows with the following message:

  "The CRC of the MBR boot drive or the UEFI boot loader has changed since the last system startup.
  Press a key to enter setup. »
  To continue, I need to go into the BIOS Setup, output without any change, then Windows loads normally.  This repeat on the next reboot.
  I have run chkdsk on the drive system (c :)), and no problem not found.
  What would do this, and how can I change it?

  I have never activated this setting on my laptop. I don't know exactly what it checks - if it's just the MBR or other things like Bootmgr and BCD. On a system with only Windows 7 installed, I don't expect the MBR and Bootmgr to change after installation. If this started after an update? Reliability Monitor may show changes with has occurred around the time it started.

  I guess that the Fujitsu support have verified that you have the most up to the date of the BIOS. Have you tried to disable the warning of viruses and then allowing him once again in which case it must be reset? Even if it is a boot virus, I don't expect to be changing in order to cause the detection at each start. If you want to eliminate this possibility, it is preferable to use a virus scan offline as Windows Defender in offline mode.

  An outside possibility is that Webroot is something clever with these files that is causing the problem.

  You can reset the MBR and Bootmgr using the method here:

• The CCITT u - Law encoder settings

  HI - please forgive my ignorance, I have much to learn about recording audio, but I searched on the web and these forums widely as well as trial and error and I'm stumped.

  I just a copy of Adobe Audition and have been invited to create audio messages to a phone connection system (CISCO) unit.

  The settings that I received are as follows:

  Flow rate: 64 kbps

  Audio sample size: 8 bit

  Channels: 1 (mono)

  Sampling frequency: 8 kHz

  Audio format: CCITT U - law

  I think I found where to adjust them all of the above except the audio format.

  I found information announcing that these audio prompts can be created with hearing (even recommended), but no real step by step instructions.
  I also found a few free conversion tools. I tried registering with the hearing and conversion. The quality is severely wrong parcel after conversion. I guess that's to be expected with 8-bit but I would like to have the best possible quality.

  I got a decent 8-bit sounding record in hearing but in the properties of the resulting file .wav file it details State parameters of the encoder: PCM:

  Considering that convert it with the free converter shows the encoder settings: CCITT u - Law

  

  SO my question is... How can I get the ecoder settings to read CCITT u - Law, during the registration/export directly from hearing?

  And advice to maximize the quality of the recording are appreciated. You can see the settings I've chosen above.

  Thanks much for any guidance you can provide.

  Best,

  Aimee

  Hi love,

  You will need to have CS6 Audition CS5.5 did not support the native export to u - Law.

  • When you are ready to export, select file > save under...
  • Choose "libsndfile (*.aifc, *.aiff.)" , as the Format, and then click on the button 'Change...' next to Parameters of Format
  • In the new dialog box, set the Format "Audio waveform" and coding for "u - Law"
  • Then repeatedly click OK to apply these settings
    

  

• Cannot be deactivated domain guessing version 37.0.2 to go to about.config

  Online suggestions have not helped, including going in Preferences > browser, because the browser is not in my version. What I need it to must stop geolocation requiring an entry "about.config" in the URL, but adds field bar ALWAYS guess www. for her, so I get error 'server not found '. Mac OS x 10.6.8. Thanks for your help.

  It is not about.config by a point, but Subject: config with a colon.
  topic: is a protocol such as http: and is used to access the built-in special pages
  You can open on: pages through the address bar.

  • http://KB.mozillazine.org/about:config

  I guess you are looking for this pref:

  • Geo.Enabled = false

  Note that Firefox will always ask for permission before using the geolocation.

  If geolocation is not used Web sites can do a reverse DNS glance upward from your IP address and is generally not very accurate.

• Airport network guess without the access control list.

  In fact, on the page AirPort base stations: on the guest network feature, Apple write this:

  "If enabled, access control lists will be applied to both the main Wi - Fi network and the network of comments. If you use Access Control Lists, you will need to add your comments network clients to the list so that they can join. »

  I think that on previous versions of the airport, it was possible to use the network to guess without the access control list.

  The idea is that only the (primary) private network should use this access control list.

  The network presupposes that is give for direct and temporary access (not necessary to access Airport utility, ask your friend and note its Mac address, restart the resort from the airport... for every friend who invited you to home)!

  Is there a workaround resolution?

  Unless you have set up a default rule 'No access' in the timed access settings, then it is not necessary to set up a rule for each "guest." Just give them the password for the network of comments and they will be able to access the network.

  IF... you have set a default rule 'No access' in the timed access settings, then you must also configure a rule for each device that you want to allow to connect with the settings for the time that the device is allowed to access the network.

• Safari screen claims to make Apple Macintosh system alert, saying: my data was in danger and telling me to call 1-844-316-5 * 5. I'm guessing it's a scam, but it is also a sign of a problem? I have to run some sort of cleaner? Thank you!

  Hello. When you click on a link in Safari, I got a screen that says: "ATTENTION Verizon Online Lic user: your Apple macintosh has been blocked." Apple Macintosh system alert! System was infected due to an unexpected error. "Immediately, certified technicians Mac 1-844-316-5 * 5" etc.  I guess it's a scam and did not call the number. But it does not suggest that I was hacked somehow? Can I launch a kind of cleaner? Thank you!

• With 2 pencils of Apple, I guess...

  So with the iPad 2 Pro (a 13 ", 10"), but a single case of stylus, I guess I'm either going to 'mark' a pencil so that I know that he is paired with Device13 or Device10 or go through the pairing process, whenever I take the wrong pencil?

  Not sure I'm wild in this topic...

  Alternatives?

  Seems to be the only solution.

  Personally to prevent permanent making devices, I'll wrap a piece of clear tape/Ribbon adhesive on one end, permanent marker allows to place some type of visible mark on the first layer of tape, and then cover the mark with another piece of clear tape to protect the brand. Permanent marker on Scotch tape is not very "stable".
