Lossy Enqueue Setup

• Covered wagon with an average of analog voltages DAQmx

  I searched through screws, I can't seem to find something that will automatically average numbers of boxcar fed into it. I am trying to create a feature of my software that will allow the dynamic configuration of the car covered with an average of some inputs. I would like to avoid hard-coding tables which are filled/rotation etc etc.. Any help is appreciated

  Thank you

  If you use a Functional Global to store the values and call that VI of two different screws, you will access the same data. You could use two Global in the functional shift registers and use a selector to place / extract data from / to the appropriate shift register. Only VI call access one commune VI at the time, so one of the caller of the screw will be 'blocked' until the first caller is done. This does not usually work for data acquisition applications high speed.

  You might consider using named queues instead of functioning overall. You might be interested in this thread on the forums of LAVA that deals with boxcar implimentations. You create a queue for each data stream and can perform functions such as "preview" queue to get all items without actually removing them from the queue. If you use a LabVIEW 8.6, there is a new feature called with loss of queues. You set an upper limit on the size of the queue and "lossy enqueue" allows to add items at the end of the queue. If the queue fills up, then the oldest data element will be lost.

• Circular buffer with reference

  I create two measurement systems that will enjoy air with instruments 13 and 10 respectively. I communicate with instruments through the series, MODBUS TCP, voltage and current. In order to synchronize the data of different instruments (which have their own data rate) in the stream, I need basically a circular buffer by instrument. I wish to add to each buffer circular instruments in a loop for each instrument and have a timed loop that records the data in a file by reading all the instruments circular buffers. Circular buffers must also be able to give me data that are not the most recent data.

  How can I create a circular buffer that I can add items to a loop and read another looping? I would prefer something but who uses a reference that I can pass both the loop of the instrument (producer) and save data of loop (consumer), like the queue works in Labview, I don't know how to implement this in a good way.

  Use LabView 2010 Fall edition...

  Thank you

  Native queues in LV 2010 allow you to create a circular buffer if you are using the antiderivative of Lossy Enqueue.

  Warnings:

  1. You must specify the size of the queue when get everything first, if you can not resize dynamically.
  
  
  2. To play the buffer, you can use the primitive that returns the queue information and wire a T in the items back? entry (very important to remember it). This will create a copy of the data in the queue.

• Smart way to save large amounts of data using the circular buffer

  Hello everyone,

  I am currently enter LabView that I develop a measurement of five-channel system. Each "channel" will provide up to two digital inputs, up to three analog inputs of CSR (sampling frequency will be around 4 k to 10 k each channel) and up to five analog inputs for thermocouple (sampling frequency will be lower than 100 s/s). According to the determined user events (such as sudden speed fall) the system should save a file of PDM that contains one row for each data channel, store values n seconds before the impact that happened and with a specified user (for example 10 seconds before the fall of rotation speed, then with a length of 10 minutes).

  My question is how to manage these rather huge amounts of data in an intelligent way and how to get the case of error on the hard disk without loss of samples and dumping of huge amounts of data on the disc when recording the signals when there is no impact. I thought about the following:

  -use a single producer to only acquire the constant and high speed data and write data in the queues

  -use consumers loop to process packets of signals when they become available and to identify impacts and save data on impact is triggered

  -use the third loop with the structure of the event to give the possibility to control the VI without having to interrogate the front panel controls each time

  -use some kind of memory circular buffer in the loop of consumer to store a certain number of data that can be written to the hard disk.

  I hope this is the right way to do it so far.

  Now, I thought about three ways to design the circular data buffer:

  -l' use of RAM as a buffer (files or waiting tables with a limited number of registrations), what is written on disk in one step when you are finished while the rest of the program and DAQ should always be active

  -broadcast directly to hard disk using the advanced features of PDM, and re-setting the Position to write of PDM markers go back to the first entry when a specific amount of data entry was written.

  -disseminate all data on hard drive using PDM streaming, file sharing at a certain time and deleting files TDMS containing no abnormalities later when running directly.

  Regarding the first possibility, I fear that there will be problems with a Crescent quickly the tables/queues, and especially when it comes to backup data from RAM to disk, my program would be stuck for once writes data only on the disk and thus losing the samples in the DAQ loop which I want to continue without interruption.

  Regarding the latter, I meet lot with PDM, data gets easily damaged and I certainly don't know if the PDM Set write next Position is adapted to my needs (I need to adjust the positions for (3analog + 2ctr + 5thermo) * 5channels = line of 50 data more timestamp in the worst case!). I'm afraid also the hard drive won't be able to write fast enough to stream all the data at the same time in the worst case... ?

  Regarding the third option, I fear that classify PDM and open a new TDMS file to continue recording will be fast enough to not lose data packets.

  What are your thoughts here? Is there anyone who has already dealt with similar tasks? Does anyone know some raw criteria on the amount of data may be tempted to spread at an average speed of disk at the same time?

  Thank you very much

  OK, I'm reaching back four years when I've implemented this system, so patient with me.

  We will look at has a trigger and wanting to capture samples before the trigger N and M samples after the outbreak.  The scheme is somewhat complicated, because the goal is not to "Miss" samples.  We came up with this several years ago and it seems to work - there may be an easier way to do it, but never mind.

  We have created two queues - one samples of "Pre-event" line of fixed length N and a queue for event of unlimited size.  We use a design of producer/consumer, with State Machines running each loop.  Without worrying about naming the States, let me describe how each of the works.

  The producer begins in its state of "Pre Trigger", using Lossy Enqueue to place data in the prior event queue.  If the trigger does not occur during this State, we're staying for the following example.  There are a few details I am forget how do ensure us that the prior event queue is full, but skip that for now.  At some point, relaxation tilt us the State. p - event.  Here we queue in the queue for event, count the number of items we enqueue.  When we get to M, we switch of States in the State of pre-event.

  On the consumer side we start in one State 'pending', where we just ignore the two queues.  At some point, the trigger occurs, and we pass the consumer as a pre-event.  It is responsible for the queue (and dealing with) N elements in the queue of pre-event, then manipulate the M the following in the event queue for.  [Hmm - I don't remember how we knew what had finished the event queue for - we count m, or did you we wait until the queue was empty and the producer was again in the State of pre-event?].

  There are a few 'holes' in this simple explanation, that which some, I think we filled.  For example, what happens when the triggers are too close together?  A way to handle this is to not allow a relaxation to be processed as long as the prior event queue is full.

• Apple Watch unlock Mac Setup Frustration

  I own a first generation of Apple Watch and an end 2013 13 "MacBook Pro and last mac mini (i5). I went through the entire setup process to have my watch unlock my MacBook several times. (All along the) When I get to choose the button "Allow your Apple Watch unlock your Mac", it runs for awhile and then I get the "unable to contact Apple Watch" fast. It seems to be my watch because if I try and let the Apple Watch locked, she'll tell me to unlock, and then try again. Happens on MacBook Pro and mac mini in the same way.

  I tried to research on this problem and we tried all authentication reset to two factors for an agreement again all settings and turn it on again.

  Any thoughts?

  Thank you!

  Hello pgirardi,

  I appreciate that you try to unlock your two computers using your Apple Watch with watch OS 3.  The resources below provide the steps and requirements to do this.  I would just try it with a single computer until you have a job before trying the second computer.

  Automatically unlock your Mac with your Apple Watch
  
  

  The first time you open a session after you turn on or restart your Mac, connect by entering your password manually. After that, Apple Watch connects to you.

  Set up automatic unlock

  Make sure your Apple Watch uses watch OS 3, and your Mac to mid-2013 or newer model uses macOS Sierra.
  For more information, see system requirements of continuity.

  Automatic unlocking

  Automatic unlock works with these devices and operating systems:

  watchOS 3	macOS Sierra
  Apple Watch (1st generation) Apple Watch series 1 Apple Watch series 2	MacBook (early 2015 or newer) MacBook Pro (late 2013 or newer) MacBook Air (mid-2013 or newer) Mac mini (late 2014 or newer) iMac (late 2013 or newer) Mac Pro (end of 2013 or later)

  Make sure your Apple ID to use instead of the two-step verification two factor authentication. Learn more.

  Make sure that your devices are configured as follows:

  • Your Mac has Bluetooth and Wi - Fi enabled.
  • Your Mac and Apple Watch are connected to iCloud with the same Apple ID.
    On your Mac, choose Apple () menu > System Preferences, and then click iCloud.
    On your iPhone, open the Apple Watch app, then go to general > Apple ID.
  • Your Apple Watch uses a password.
    On your iPhone, open the Apple Watch app, then type the access code.
  • Your Mac has "allow your Apple Watch unlock your Mac" selected in Security & Privacy preferences.
    Choose the Apple menu > System Preferences, click on Privacy & Security, then select the general tab.

    

  pgirardi, if you are unable to unlock your main computer after trying these steps, then you will need to cancel the match your iPhone and Apple Watch and try again.

  Cancel the match your iPhone and Apple Watch

  Take care.

• Setup various AE advise

  I have problems to get the maximum speed. My ISP is 150 MB and I have this Setup:

  Airport Extreme (6th generation) placed in the living room connected to the Ethernet modem (modem is bridged, no router). When I connect this way, it gives me 130-150 MB, which is fine.

  However, when I connect these devices all starts to vary:

  1. an other Airport Extreme (6th generation) is connected to the hand on. Expansion of the network. When I try to change the option expand Network turn off this airport restarts but never succeeds and gives me an error. The only thing I can do is add then reset again and then I can only use the extension of the network. This normally works very well but do not know what it might cause the heavy fall.

  On this second AE Ethernet port I have attached a Synology NAS with my music, and so on

  2. an Airport Express (A1392 3rd gen) that I now set to join the network to see if things would improve. This one I use for music and it has a smart thermostat bridge (Tado) plugged into the Ethernet port

  3. an Airport Express (A1392 3rd gen) which I used to use to expand the wireless network but have disabled now I read that the extension of the network makes the slower WIFI and I'm afraid the Express slows down the extreme speed AC but not sure about that.

  4. a Time Capsule from Apple (4th gen) which I use for backup. I disabled the connection here as I believe join or extend the network would be to ask questions. I have attached a few devices through Ethernet at the back of the TC.

  The various airports are in different places in my house but not more then 10 meters (30 feet) on the other.

  That Setup would you recommend in order to get the best speed in different places?

  Thanks for the help!

  1. an other Airport Extreme (6th generation) is connected to the hand on. Expansion of the network.

  If you extend the network using a wireless connection between base stations, it will be the first performance issue you will encounter. It would be preferable to extend it using a wired connection between base stations. This is known as a roaming network configuration.

  2. an Airport Express (A1392 3rd gen) that I now set to join the network to see if things would improve. This one I use for music and it has a smart thermostat bridge (Tado) plugged into the Ethernet port

  In this configuration the AirPort Express performs like any other client wireless on your Wi - Fi network. He also performed an Ethernet bridge wireless for the Tado. It does not perform routing functions, or it extends the network. In addition, please note that the A1392 is a base station 2nd generation 802.11n. There is no 3rd generation... yet.

  3. an Airport Express (A1392 3rd gen) which I used to use to expand the wireless network but have disabled now I read that the extension of the network makes the slower WIFI and I'm afraid the Express slows down the extreme speed AC but not sure about that.

  Yes, what you read is correct. Again, you can reduce the amount of the penalty to performance of a network using a network of itinerant type instead. This requires not all base stations to be connected by Ethernet.

  4. a Time Capsule from Apple (4th gen) which I use for backup. I disabled the connection here as I believe join or extend the network would be to ask questions. I have attached a few devices through Ethernet at the back of the TC.

  How this time Capsule is connected? Wired or wireless and other base stations? For the record, it cannot be configured to 'join the AirPort Express wireless network'.

  The implementation of recommendation would be a roaming network.

• the iTunes Setup program finishes, but the application does not appear

  For starters, I'm on Windows, but it seems that the system is not the problem because it's happened before, with my Macbook Air.

  I download iTunes on Apple's site and Setup will run as usual and finishes. But iTunes never displayed in Program Files, the destination he was supposed to have downloaded. I opened the Task Manager and tried to manually run the program yourself by using 'itunes.exe', but he writes that the application does not exist.

  For general advice, see troubleshooting problems with iTunes for Windows updates.

  The steps described in the second case are a guide to remove everything related to iTunes and then rebuild what is often a good starting point, unless the symptoms indicate a more specific approach.

  Review the other boxes and other support documents list to the bottom of the page, in case one of them applies.

  The more information box has direct links with the current and recent if you have problems to download, must revert to an older version or want to try the version of iTunes for Windows (64-bit - for older video cards) as a workaround for problems with installation or operation, or compatibility with third-party software.

  Backups of your library and device should be affected by these measures but there are links to backup and recovery advice there.

• That means "bad connections" warning to the average of the Mail account setup?

  The Mail account setup dialog box, the works of autodetect IMAP, but after clicking "Done", a warning is displayed (see image), declaring "Thunderbird may allow you to get your mail using the supplied configurations." However, you must contact your administrator or your e-mail provider about these incorrect connections. See the Thunderbird FAQ for more information. ».
  I checked the Thunderbird FAQ (or what is the information that I found) but there is no explanation of this warning.

  On the connection used:

  -C' is a working IMAP with STARTTLS on port 143

  -the server is using a self-signed certificate (not expired), which Thunderbird complains not in the warning

  -with the help of a Setup from another existing SMTP account (no control in the Mail account setup dialog box)

  So I ask myself, what this warning is really all.
  Best regards

  Watch dialog box seems to occur only if:

  • There is an e-mail account, SMTP outgoing self-signed certificate
  • The new e-mail account uses the only existing outgoing SMTP Protocol

  This could be a default in Thunderbird 31.7.0, because there is only one such warning dialog to the configuration of the e-mail account that is used for reporting several different problems. The code (source Thunderbird: mailnews/base/prefs/content/accountcreation/emailWizard.js) power switches of the incoming and outgoing messages, but in this particular case, it seems to turn off all messages - which leaves just the text displayed in the screenshot - compare to https://support.mozilla.org/en-US/kb/server-doesn ' t-use-encryption

  When you use a new profile without all accounts in Thunderbird 31.7.0, new account creation work without such a warning.
