LV: Sending 'sync' to get synchronous acquisition of CDN
Hello @ all
First of all: my knowledge on the bus CAN generally is not very good, so excuse a description of the possible problem.
My task is to read the devices CAN messages. This works very well for devices that send their messages 'stand alone' with a fixed repetition rate (here: 100 Hz).
But other devices do not send their messages with such a high repeat rate. They send their message only until they come in an overflow (here: after 150ms). I ve heard that I send a message "sync" for devices to get their message across. This means that I have to send the message of synchronization with the 100 Hz for the acquisition of 100 Hz.
My question: How can I have to set such a two-way CAN transfer? Of course, I can send a synchronization message and read the reply. But what it takes when I want to read for example 10000 messages? I Don t want to trigger it by software because of the accuracy of the timer.
What should I just start "CAN read.vi" and the parallel of "CAN write.vi"? Or is it possible to start the write.vi and the read.vi at a time determined, to obtain two parallel functions?
Tanks so far.
Hi LittleJoe198,
I'm not quite sure what exactly is the problem. I only know "sync messages" in the context of CANopen. But your question indicates that you are using the API of frame. Maybe you mean sending frames remotely?
You could use the CAN objects to transmit data periodically using material timing (only supported on PXI/PCI/PCMCIA-CAN cards). Take a look in the example finder LabVIEW (hardware category of entry and exit > CAN > frame API > base), "CAN transmit - periodic.vi.
It is not a problem sending and receiving on the same port, see example 'send receive same Port.vi. "
You should also take a look at the manual CAN Hardware and Software (START > programs > National Instruments > NI-CAN).
What kind of material CAN do you use?
Let me know if you have any other questions.
Kind regards

When I try to sync, I get a message that I need to update iTunes.
When I try to sync, I get a message that I need to update iTunes. I used this button on iTunes 11.4 since it was bought, then today he refused to sync. I deleted and restored, which erased all the data and my music. I always get the same message, but now I have a Clipboard instead of a key. Any help would be appreciated.
iOS 9 does not synchronize with a version of iTunes below 12.2. So, you've been 11 iTunes syncing, but once you upgraded to iOS 9.x, the required level of iTunes has changed.
You will need to download the latest version of iTunes to synchronize.
Great win by the Packers, BTW!

I took several pictures on a recent trip, and when I highlight, click on send to:, I get this message: error: 0x8cccD040. I thought to go to settings and check for this possibility, but I don't really know how to enter in the settings. I am not informed on the evolution of info, etc, so do not know what to do here. I read several reviews, with some saying it could be my protection antiviruss, or my e-mail settings, settings etc but not sure. My antivirus is McAfee so that needs to be known.

I already have a sync account, but I don't like on any other device now I want to just save my settings on this computer browser right now. Want to replace anything by what I have here but she again just put me into something the device. I want to re add other devices later. Even I don't think that I have on my iPhone right now.
It's frustrating!Reset your FireFox sync, so you can replace the previous data synchronized with the data of the current computer.
See below for the detailed procedure & illustrations

I continue to add music to my computer library; but my iPod may only contain a part of this content. I would like to be able to periodically change the contents of the iPod. How can I select which albums on your computer get synced to iPod?
Yes, the easiest is to synchronize the device with one or more playlists selected. Over time, you can either edit the lists themselves, or lists are synchronized, or do the smart playlists that automatically rotate content on and off the device over time. For example, you might have a size limit to more recently, added another for most recently played and a normal playlist for the most part.

I created an account in Firefox, but when I try to connect to sync I get a gray white screen
I can't access it via Options/sync either. That just gets me a message saying "determining the State of your account..." "that never goes away. I refreshed FF, verified I am connected to FF and checked around on Google for all possible solutions but no luck.
Try to delete the signedInUser.json file in the Firefox profile folder and delete the folder of weaving (Sync was formerly known as armor).
If that is not enough then delete the prefs.js file to reset the prefs and may also remove the compatibility.ini file to reset the profile. -
Use sync to get my profile (without key - without reset my sync account)
I have recently installed Firefox Sync, or so I thought. I went through and finished what I thought was my stored profile. I didn't know that I was given a recovery key. But apparently I was. At the end of the day I backed up, and when I go to the online part of the synchronization, it shows that I have stored information. I'm kind of a loop here.
Because for one I can't seem to manage my account option it said to try if you have lost the recovery key, because it won't let me sync. So basically I'm confused as to how I should get my information in my profile.
To make this clearer.
Steps that my work.
1. the firefox sync Installer
2 wipe the computer and reinstall firefox
3 try to sign firefox Sync - good
4 try synchronization (no key) - badAlso if there is anyway to generate a new key without wiping all my information on sync I would greatly appreciated it was years and years of Favorites/add-ons, etc.
I'm really desperate enough, right now, my computer barely works and now I can not even the bare minimum at work. =(
Sorry, without the original key to the recovery of your data synchronization are unnecessary. That 'key' is the encryption key, without your key figures cannot be decrypted.
You have another device using this account for synchronization?

We send 5v data acquisition using a voltage generator. Hook us it up to a voltmeter and see 5V. When connect us the generator voltage to a valve "normally open" parker, the voltmeter indicates .14V. It seems that when we connect the two sons of the valve for the voltage generator, the son act as pattern. We want to control the voltage flowing to tap through Labview. We checked the wires to the valve and they work very well, because if we send a constant 5V since the acquisition of data and put ashore, she, the voltmeter indicates 5V. Someone knows why the son act as pattern and low blood to .14V?
nsatpute wrote:
Our data acquisition is NI USB-6259. The valve requires only a 5V max and our DAQ provides up to 5V. However, after connecting the valve to the acquisition of data, the grave tension to almost 0. We start from the principle that the son somehow act as the reason, but we are not sure if this is the case.
The question here is not how much voltage the valve wants, it's the current needs of the valve. The 6259 can put only 5mA via an analog output. Your very likely tap needs much more than that. If you need to add in an amplifier circuit that can supply more current to operate your faucet.

Hello
I have a laptop (Compaq 8440) running Windows Vista Enterprise (not yet upgraded to SP1). I have a shared folder mapped to the N: drive on my laptop. This shared folder is located on a computer on my home network. Every day, I move my laptop between my home network (wireless) and my work network (cable intranet).
I scored a subfolder in the shared folder available offline. It worked for about two weeks, but now when I try to synchronize with the shared folder offline files, Sync Center has constantly "waiting for synchronization" status He never goes out with synchronization, regardless how long wait.
I tried clicking "stop"button in Sync Center, but this does not prevent the synchronization. I do not see error messages or the situation in Sync Center.
I tried to restart the laptop, but nothing helped. I tried to disable/reactivate the wireless connection, but nothing helped. I can connect to the shared folder and discovers the other directories that are not 'available offline", is not a connectivity problem.
Thank you
Jason FritzHi Jason,
You can try to remove the sync partnership and add it back. Who can get things working again. See the following link on how to put an end to partnerships, then in the section above, how to create them.
