• Urgent: continous recorders of NIDAQmx and other instruments with multi-threaded vc ++

  I'm working on a software with vc ++ to control several instruments including a NO-DAQmx6289. For example, the features of the software.

  1. communicate with data acquisition card (card data acquisition) and continuously acquire data from several channels at a frequency of 1 kHz.

  2. connect with function via port RS232 1 generator, sending triggered bursts to the real-time features generator change state Ultrasound (G_usstatus) variable.

  3. connect with optical switch via RS232 2 port, send signals to switch between the two input channels (0,1) and six output channels (2,3,4,5,6,7) to the specified user to sequence and time interval (default: 150 ms), real-time change the channel connection variable (G_optchannel).

  4. in real-time, record data and the corresponding ultrasound status and connection status of optical channel in a specified file use for later analysis.

  I use multiple threads to make data acquisition (1-wire), control of the function (2 wire) generator and optical switch (3 wire).  I also need save data acquisition of data and the corresponding ultrasound status and use the connection status of optical channel in a specified file for later analysis. I use the following codes to read data continuously.

  Now the problem is the data acquired with daq card does not match the corresponding registered swtich optical status (G_optchannel, which specifies the light connecting channels). High readings expected certain status really appeared in any other situation.  It seems that there is a misalignment of the multi-thread data. Because the optical switching State passes to 150ms, so I put DAQmxRegisterEveryNSamplesEvent to be trigued each 50samples, which means 50ms with 1 kHz sampling to avoid missing the changes. I also check if there is any change of status during the DAQmxReadAnalogF64, by registering l_optstatus_s and l_optstatus_e, which are actually the same. I wonder if this is because the data are first registered in the buffer. When the software starts reading, at that time, optical swtich status no longer reflects the State when the data was recorded first. Is it possible to fix this?  Thank you very much!

  kGy,

  I'm glad to hear that you are progressing with your project.  Timestamp data are always a bit tricky, because the process of querying a counter on the CPU is done asynchronously with the acquisition of your DAQ hardware.  However, your equipment will ensure that the relative chronology between samples is consistent (in your case, the data will be sampled every 1 ms).  And since you have changed your program as you are now all samples acquired reading, you know that each sample follows the previous 1ms.  So, if I were to implement this I think that I take an initial horodotage when I started the task and to calculate the timestamp for all samples following this timestamp (timestamp SampleN = (*.001s + horodotage initial N) or timestamp SampleN = timestamp SampleN 1 +. 001 s).

  I would go to do that, rather than the timestamp of the end of the reading for the following reason.  As I mentioned previously, the reminder of your reading will run when the OS is planning.  Therefore, it is possible that it gets delayed or does not exactly in phase with the acquisition of hardware, and make adjustments to your code to handle this problem.  However, when you're timestamping there is another thing to pay attention to.  It's the fact that your hardware has a FIFO where sampled data can accumulate before getting transferred to the memory buffer that reading from (for example if the bus PCI were busy when the sample was acquired).  Now assume that the stars aligned against us and get the following:

  (1) the operating system is busy with other things, and our reminder read gets delayed a few ms.

  (2) at the same time, another device connects the PCI bus (or part of the data path between your device and the memory used for the buffer).

  (3) one or more samples is momentarily blocked in FIFO of the device.

  If you were to read data timestamp at the moment, your timestamp would reflect the data in the buffer as well as data that was flying in the FIFO of your device.  However, you can only read data in the buffer.  Thus, time stamp applied to data that you just read would be a millisecond or two later they should be.  Suppose that on the next read reminder, this condition has cleared up itself.  This timestamp taken here would be accurate, however, you will need to return some additional samples (those who were stuck in the FIFO last time).  If you backcalculation your timestamp at this stage, I think that the timestamp calculated for these ecaple timestamps calculated on the previous reading.  It wouldn't be ideal, nor would it reflect when the data has been actually sampled.

  One of the remaining challenges is how exactly the start of time stamp feature.  To do this, I would like to add a call to DAQmxTaskControl (taskHandle, DAQmx_Val_Task_Commit) before calling DAQmxStartTask.  This step will advance the State template DAQmx as far as possible without actually starting the task.  This will help to DAQmxStartTask as soon as possible.  Now, before the appellant beginning or immediately after, I would take my initial horodotage (perhaps timestamp before and after and take the average).  Then I would use this original time stamp and my sampling rate known to calculate timestamps for all the rest of my samples.

  That got a bit long, but I hope it has been helpful.

• different rates in multi-clip

  I turned a conference with 2 cameras. One is 29, 97i and the other at 23, 98p. I did an edit multi-pince. I noticed the movement of 29, 97i camera is choppy. What should I do to correct this?

  Jerky in what way? Jerky stabilization? Where are you seeing this? In the clip of browser? In the multicam Editor? In the project? What frame rate is the multicam clip and the project?

• problem with marking albums multi disc

  In the past when I have an album that has say 3 CD, I was able to right click > get information, then place the disc 1 of 3, 2, 3 and 3/3. In my case music files would then appear as 1-01, 02-1 right through the first disc and the 2-01, 2-02 and so on.

  Now, I do the same with itunes 12 but in the folder it now appears as the title of the 01 01 title song, 01 song title then 02... It does not differentiate which is drive 1, 2 or 3. Is it possible to go back to the old way to do.

  You'll be amazed how much multi discs, I have...

  Any help appreciated

  Let iTunes do file management and don't worry in this regard. Your only interaction with your files either through the iTunes interface, where questions of multi-disc are correctly identified.

• When Fire Fox support (again!) for display of multi column (and navagable) Favorites (bookmarks)?

  I always use rev 31. This is the last version that is compatible with the add-in on, "Multicolumn Bookmarks 1.5', I have several brands of books collected over the years and the single column format is frustrating and not helpful."

  Asked to provide a current version, which is compatible with "MultiColumn Bookmarks 1.5' Fire Fox, or provide a favorite navigable multi-column as option display in a near future program revision Fire Fox.»

• How can I get multi channel audio via the HDMI port on an early 2015 MacBook Pro?

  I try to get the 7.1 audio channels to flow from my MacBook Pro to a cinema set up. The display works fine now I plug the HDMI in however the sound still Mac speakers. I checked the settings and no HDMI output is available. An airtime option is available, but that returns only two channels as a maximum to the receiver. When I go to the configuration of the source on the receiver it receives video at 1080 p 60herts however it is specifically stated No Audio from the Source.

  Also, I have connected my iPhone 6 s more using an Apple through the same HDMI cable adapter and it works perfectly. We also use HDMI with our PS4 occasionally and it works perfectly, even with the 3D.

  Thus, the MacBook Pro is early 2015 with an i5, the receiver is a Harmon Kardon AVR 2700 (we run 7.1 channels of this) and we are connecting via the HDMI port through a 50 ft HDMI before. The receiver sends the audio to a projector with 1080 p 60 hertz if it changes anything...

  Also if it helps the receiver supports dts - hd master audio decoding, Dolby True HD/Digital Plus decoding, HDMI 1.4 (HDMI is compatible 2.0), as well as multi-channel input and PCM and linear PCM.

  I use a "Behringer UCA202' audio device I bought on amazon.com for only $29.

  It works very well for the audio 5.1 or 7.2. Works connect optical toslink. Just plug it into a usb port on your Mac and a cable optical toslink to your AV receiver.

  My Yahmaha 7.2 audio/video receiver is measuring process the digital signal in THX, DTS, Dolby digital Pro logic, a cinema, etc.

  

• How to preserve the multi-level iPhoto in Photos folder directory

  If you upgrade OS to Yosemite or El Capitan, how to preserve my folder customized Photos iPhoto multi-level directory? My iPhoto library is 105 GB and contains 41 000 photos, all carefully arranged in a directory of custom and subsidiary subjects.

  iPhoto (the beloved and only) has a great power in its ability to custom folders full of full of albums etc. subfolders directories several levels deep, with photos that can be duplicated in different albums, folder & file size info, etc. Unless this can all be kept in the Photos, there is no point me upgrading until Apple gets serious on the needs of demanding photographers, who want the custom control and want as their stuff protected in their hard drive and not on the cloud. Automatically generated 'events' and 'albums' are things of grandmother-and-the-children, useless for people like me. I need a custom control over making inventories of multiple folder levels based on my own custom categories, categories or undated events Apple thinks we should have. Home, school, family, travel, etc. just does not cut it!

  Someone really aware with this situation can help me get clarity? Promo stuff on pictures Apple responds to virtually none of my questions.

  I would like to begin by asking in the forum of Photos, but until you do, you need to specify your terminology. iPhoto offers events, Albums, and smart Albums for the organization. Thus, by "directories" I can only imagine say you you have files of records nested within other folders? If so, you can do with Photos. There is no need to use the features of cloud Photos. They are not mandatory in any mode.

  Regarding your comment, if you're a serious photographer why you use iPhoto? Make sure you used Apple app for photographers, it was called Aperture. Now for photographers you use applications 3rd party - Lightroom, Capture One etc.

• Multi-port USB adapter for the MacBook USB - C Port?

  Hello

  I'm in pain, trying to find a USB adapter multi-port for my MacBook 2016, which only has a single port USB - C which is also like a power port.

  I already done is connect the WD My Passport drive external HARD to the MacBook via an adapter HooToo, that to see any HARD drive mounted in OS X.

  OS X makes a sound when it is connected, but apparently the adapter provides insufficient power for the HARD drive needs to be loaded.

  I got Belkin USB multi-port here:

  http://www.Apple.com/us/search/USB-ports?SEL=accessories & src = SERP

  But it is not certain if one of them provides enough power, so I would try rather than a person has used successfully with a MacBook and an external HARD drive,

  If not, opt for a multi-port adapter USB brand Apple.

  Please let me know about your experience or an Apple adapter.

  Thanks in advance

  My Apple 3 port works as advertised. The USB port has a perfect compatibility with the old and readers USB 3, my adapter Ethernet USB Apple and Trendnet USB adapter that I use in series. This includes the perfect function with a 10 VM Windows via VMware Fusion.

  A non - Apple C to an adapter that I bought works fine too. I don't see the brand on this subject but he chose via Amazon ratings. There were some with higher ratings, so that's how I made the choice.

• a separate album multi disc set

  I can't for the life of me, see why a created disc multi disc shows separately for the album.

  This is the Portrait of Dan Fogelberg, 4 CD set. I did read the information and changed the orinal separated from 4 albums at all with the same name.

  Deleted "Disc X" in the title of the album. So disks 1,3,4 now appear under an album for the album, but disk 2 shows upward in a separate album.

  What's funny, is that if I go to the windows folder, the MP3 from all 4 disks are in the same folder. Watched a lot of attributes through windows Explorer

  and they all seem compatible. I also did the same Album artist for all. Any other ideas? I even deleted and ripped out again to see if that would clean things up.

  Im running the latest update of iTunes in Windows 7, if that matters,

  Thanks for all the ideas.

  I had a similar problem recently... try to remove the title of the album of all disks, so you get the artist with the unknown album, then readd the title of the album.  Worked for me
