• Working with USB high speed Interface Modul 2.7 in LabVIEW

  Hello

  is there an example works with a USB high speed Interface Modul 2.7 in LabVIEW?

  The EGG is a "Cypress CY7C68013A-56PVXC»

  Thank you

  Best regards, patrick

  Hi patrick,

  I searched on google for the module. The manufacturer is Braintechnology.
  If you need a LabVIEW driver ask them please, maybe it's that they can provide you with a.

  Braintechnology offers a DLL - USB. With a little work, you can include this dll in your LabVIEW project (call library function node).

  The following documents explain how to:

• HP dx2000MT: why fan runs on high speed

  Hello, the fan in this machine works sometimes at high speed, can someone tell me why or what I can do to stop this please?

  The most common cause of a computer running at max speed fan is a processor overheating.

  This can be caused by:

  -Extended heavy load on the processor.

  -Malware can cause this.

  -If you use many programs at the same time as background tasks, who will do as well.

  -Dirty/dusty in the computer heat sinks.

  -Malfunctioning components from the motherboard.

  -Bad placement of the computer.

  -Desktop computers should be placed where they receive lots of air circulation.

  -They should also be placed away from heater vents / air conditioning floor. AC vents may be tempting to cool the machine but will cause condensation and destroy it.

  -Observe the fresh air intakes where on the computer. Generally low and/or front of the chassis. If there is a substantive contribution, move the unit out of the carpet and on a hard surface.

  -Do not keep the Tower in a small enclosed space. Computer Cabinet should never have the door closed with the runinng machine.

  -If it was a laptop, you also to maintain it on a soft surface such as beds and prefer to use it on a desk, or on the binder or other similar when surface into the fold.

  -Vista-era of HP computers are completely garbage as well. (Sorry HP, but it's true). Watch by substituting a newer computer. The new HP machines are not nearly as terrible as those made when Vista was released.

• high speed streaming

  LabVIEW 8.5

  Hi all. I have never written LV or any other code to make streaming broadband but I have to now. I did a lot of 2 and 3-way low speed data acq but never down. I could use a little guidance as to how it works.

  First of all - what I have to measure. I am able engine valve motion, in real time on a test apparatus part motor engine. I enjoy movement to a slow control RPM can accelerate to maximum speed while taking data. The scan will take 5 to 8 seconds.

  2nd - I need to watch. I need to look at the position of the valve for 1 round, taken in 720 points, at low speed and compare it to track even the test RPM. I have to select test RPM after the data are obtained and overlay lo & Hi plots, a control and a test track at the same time. All the analyses to be performed after data collection, not in real time. Sampling of the range starts at around 12 k samples/s and a ramp at 66 k samples/s up to 8 seconds, which will generate up to 312 000 points by scanning.

  3rd - I. High speed laser sensor position, more than adequate sampling rate. Rotary encoder, 720 cards data acq pulses/Rev. and chassis conditioner GIS with inputs / outputs. Boards are 6143-PCI and PXI - 6071e. 6143 Board is connected to the encoder and entered trigger. Output laser is 0 - 10v, so I have to use the jury 6071e for analog position signal.

  Now, my questions. I know that I can stream to get a high rate, but for analysis, I need to bite these data into pieces of 720 points and they relate to a registered PLAN. It can be analysed by discrete steps, say about 50 or 100 rpm. How to handle a stream from a writing Board and "stamp" with RPM taken of an encoder on a second table? I'm looking for some basic procedure here that will give the data for me in a way that I can actually use rather than a dump of 312 000 point that would take days to analyze without a few things. I calibrate the data after the fact and analyze in a separate program, so I just need voltage data flow. But I need to start at the pulse of Z and take a reading every pulse.

  Thoughts?

  I had LV 2012 running when I responded to your post above.

  I called LV 8.5 and put together this small VI.  It generates random numbers to approximately 66000 per second and runs for about 8 seconds.  It requires approximately 17 MB.  The screen requires a copy (I think) which roughly doubles the size of the data in memory.

  Reduce the wait to 1 ms and it runs in about 1 second.  It takes a zero waiting ms 76 ms.  Then save the data in a shift register or another form of memory will not be a bottleneck.

• NEITHER 9213 changing high resolution at high speed. Screenshots included.

  Hello

  I have a card 9213 in a CRIO-9074. My sampling rate is exactly 1 s/s, which means that it is running in mode high resolution. However when I go in the project window and change it to high speed (as indicated below)...

  

  nothing happens. Remainders of 1 s sampling rate / s. below you can see my labview vi, which is a timed loop. The period can be changed in the loop is only how many samples I trace on the graph. And as you can see on the graph to 100ms graphic flatlines as the 9213 is not updated of its value.

  

  Below you can see the record of the following data and it shows that the sample time is exactly 1 s/s.

  

  So, how can I actually get my 9213 OR change of 1 s/s mode high resolution at the 75 s/s, that it is rated for mode high speed. For this initial Setup, I use only 1 thermocouple, but once I get the included sample rate I'll add more. It should also be noted that I rebooted the computer and the Committee for the acquisition of data several times.

  Thank you.

  I noticed that in your project beside the cRIO, he says "in time real features not available."  According to another thread, I found, it was because the module time real wan not properly installed:

  http://forums.NI.com/T5/FieldPoint-family/real-time-features-not-available/m-p/954231

  Also, when I recreate your project settings, if I right click on the 9213 module I the ability to "Deploy" or "deploy all.  Deployment is expected to update the settings.

• acquisition of data high-speed and simultaneous sampling

  I'm quite familiar with the coding for NOR-DAQ boards in Labview. What worries me with labview, is that each tick is about milliseconds. I intend to retrieve the data simultaneously from 32 channels at 2 MS/s/chan using SMU 6368 s. Wouldn't not possible to enter data, on average 20 to 50 samples to get a unique value, perform simple algebraic manipulations on it and send it to the PC / software to approximately tens of kHz? We already have labview code to perform similar tasks, but it is quite slow and limiting the rate of experience. I said that Simulink is slightly better than Labview in this regard, but suffers a poor user interface and that if something C/C++ offers the ability to perform at high speeds with the same cards OR data acquisition. Could someone advise me please on this issue?

  You can use your PC! You can use a PCI/PCI-e card as the interface to your computer and it should work perfectly. Take a look at these pages (http://sine.ni.com/nips/cds/view/p/lang/en/nid/10389) for more information.

• Treatment of LabVIEW data and high speed data acquisition C

  Hi all

  I am designing a data acquition VI high speed of 3 cards acquition of data at the maximum speed. Data cards are PCI 2517 Measurement Computing. The sampling frequency for each card is 1 M samples/second, if the total sample of M 3/second of three cards. Problem is the LabVIEW drivers and the screws provided by the provider works very well just for a single card at maximum speed, but does not support multiple cards at maximum speed. Their technical engineer advised me to write code in c#, C++ or VB.NET for this data acquition high speed. If I use C forever, I would like to use LabVIEW for processing of the acquired data to data acquisition. I came across a few examples that suggest the creation of dll C code and then calling it a LabVIEW. But those who have programs simple and none of them speak in C data acquisition. My questions are,

  1. is it possible to call a C data acquisition program high speed of labview and not work in any kind of present of buffer overflow?

  2 would it not simple best to use labwindows CVI?

  3. is there another alternative solution that I'm missing?

  I'll appreciate all the entries.

  Thank you!

  Nilesh-

  It's pretty easy.  Arguments for CINrun must match wiring.  You can wire your CIN function block and say LabView to generate the C interface code to begin.

  Here's my pairs for the ASIO audio project.

• T3i sync high speed with popup flash?

  When shooting outdoors with a light background, it would be nice to be able to use the flash pop-up as a fill light (to the shadows on a face, etc..). However, the shutter speed is set to 1/200 when the popup flash is in place, overexpose the scene. Is there a reason why the pop-up flash can't sync high speed like an external flash to allow a faster shutter speed and always get a filling?

  Thank you

  David

  It has to do with the amount of energy is available for the flash.  A more powerful flash can more easily manage the sync high speed.

  Sync and sync high speed are related to the work the Shutter curtain on any SLR digital.  There are two doors.  A slides open, and close other slides.  The reason for which there must be two doors (instead of one) is because that if there is only one, then the door would slide open, then reverses to slide.

  Assume the following scenario were true:

  Suppose it takes the shutter a full 1 second door to slide open.  If we set an exposure time of 2 seconds, the following should happen if there was only one door.

  -l' shutter starts to slide open from left to right, allowing light to reach the pixels on the left edge of the sensor.  The right edge is always in the dark.

  -as slides of doors, more and more pixels are eposed to light.

  -a second later reached the opposite end and all the pixels are exposed to light, but the door must immediately reverse and start close because it will take a full second to slide the door closed.

  -the door begins to move and immediately the pixels on the edge of most on the right are in the dark, because they are covered by the shutter, but the pixels on the left edge are still exposed to the light.

  -the door has finally reached the edge against a second later and no pixel is exposed to light.

  Think to what just happened... the pixels on the edge of 'left' of the sensor got a second exhibition 2... but the pixels on the right edge of the probe were barely exposed for a fraction of a second.  You'd have a horrible blow to look.

  To resolve this problem, the camera uses TWO doors... begins a sliding open... the other follows a moment later (based on the selected shutter speed) and starts sliding closed.  Now, all pixels are exposed for the same period of time, regardless of the shutter speed you use.

  But the reality is they are mechanically sliding doors and it takes time to move.  Flash sync speed is shortest possible exposure that can be turned where the first door has enough time to COMPLETELY slide open so that when the flash goes off, the entire sensor is exposed and benefit of lightning.  The second door can slide THEN closed.

  If you do not use flash and you set a very fast shutter speed (say 1/1000th) the second door actually starts closeing long before the end of the first door opening.  In fact the second door is "hunting" the first establishes a "slot" which sweeps the sensor.

  With this in mind... now think just what a flash how to predict sync high speed.

  Assume that your camera has a maximum speed of flash-sync of 1/200th, but you want to shoot at 1/400th.

  This means that the first door must begin to open.  When he reached the midpoint, the flash must trigger to light the subject - but half the sensor did not lightning.  The second door closes as the first door continues to open up.  When the first door reaches the opposite edge, the second door will now be in the middle.  The flash needs to fire AGAIN - this time to expose the pixels on the 2nd half of the sensor.

  This means that the flash should fire TWICE in quick succession and the impulses must be PRECISELY 1/800th second (half or your second 1/400th total exposure times) apartment.    No flash would be able to recycle in just 1/800th dry if she gave a burst of the power of the light.  In other words, that it must reserve at least half of its power for the second round.

  If you increase the shutter speed to 1/800th... now the flash to trigger FOUR times and no single burst may be stronger than 25% of the power of lightning - and gusts must precisely timed occurs 1/1600e seconds, independently of the other.

  You can quickly see how this is going to require a flash with a power or you won't be able to finish the sync high speed on something more than just a few feet.

  For the light of day, the most brilliant exhibition is going to be the sunny 16 rule... f/16 with the shutter speed, the value in contrast to ISO.  So, for 100 ISO, you can use 1/100th sec.  To f/8, you can use 1/200th (and now you are still below the max flash sync speed).

• Internet high speed & 1stgen AirportExpress

  Recently I upgraded my internet speed to 150Mbps. using my (model A1264) 1stGen Airport Express, I am only able to get 50Mbps to my office. My iMac is at short range with my router. My internet is slow speed b/c my Express is outdated? A new Express will allow me received the speeds I have upgraded to or is a desperate need? On the 2nd floor, there is an another desktop or home that connects to the internet regularly (teenage son online games).

  The 1 st Gen AirPort Express and 2nd Gen AirPort Express have only 100 Mbit/s Ethernet ports, so in theory, it would be the top speed that the Express could never offer.

  To the extent where wireless is concerned, 50 - 60 Mbps would be what to expect from an AirPort Express which is provided a 100 Mbps connection, since he has never been known for its performance wireless... primarily because of a small simple antennas buried in the product.

  A new AirPort Extreme has 1 000 Mbps Ethernet ports and the much higher speed wireless capability... (six wireless antennas all located towards the top at the top of the "tower")... which would be the product to try if you want to stay with a router from Apple.  At Apple, and you buy a 14 day no questions asked return guarantees, so if the product does not wait, it may be returned for credit or refund.

• WiFi unstable and slow Internet high speed

  Hello world:

  Recently, I am facing a problem of unstable wifi, slow speed of the internet of my macbook pro. I hope someone could help me with my problem.

  
  

  Symptom:

  Internet mainly speed just unstable using a wifi connection. (no problem with wifi connection self and my wifi suddenly grave would not be)

  Example:

  • FaceTime with my friends and the connection would suddenly abandon or images & audio gets fuzzy.
  • Videos in online streaming and suddenly occurs buffering.
  • Download file of software update iPhone via iTunes, the speed is slow, he needed to take 2 h at the end and later on a window display "cannot download and check your internet connection".
  • Suddenly cannot open websites like site apple.com, google.com. Sometimes it will take more time to open Web sites.

  Hardware and software:

  MacBook Pro mid-2009, OS X EL Capitan 10.11.5

  ISP: Cox, 50Mbps

  Modem & router: Netgear N450

  Test:

  Turn off my wifi and connect my macbook pro with modem & router with cable, internet high speed is stable and fast. Internet speed download speed test result display is of around 60Mbps, download speed is around 8Mbps. And I tried streaming using the connection cable, there was no buffering.

  I already tried the possible Solutions:

  • Restart the Macbook pro and restart Modem & router: will not work. I mean the internet will be very well at first, but later would be unstable again.
  • Reset Wireless Modem & router and change channels: useful, but not completely solve the problem. After you change the wireless channel, I tested my internet speed and the result showing 20-40Mbps (slower than 60mbps) speed download. Sometimes, the result will be like 6-8Mbps and sometimes it will be 60Mbps. If its unstable.
  • Wireless diagnosis: result indicates connection is good.
  • Called my ISP provider: they checked and said all right.

  
  

  Other Questions & details:

  • The internet is ok for most of the time. But when all of a sudden I can't open site or I can't download and streaming & FaceTime at normal speed, his frustration.
  • I thought it might be related to my hardware since its an old macbook pro. I can't run Apple hardware test because I don't have the installation disc more and my macbook pro is very old. Is it a third party software that can perform the test hardware on mac?
  • My wifi used to be very stable and I don't have to worry. Just for these last two weeks.

  
  

  
  

  I really appreciate your time and help! Looking forward to any reply!

• Super High speed internet Time Warner installed (50mbps) but foxfire operating only at 1.35Mbps, while the internet Explorer works fine

  Internet (50mbps) Time Warner installed high-speed yesterday on my computer, but when the guy left I noticed that the speed was very slow. SIS one test on speedtest.net and found I was getting a maximum of 1.35mbps (sometimes as low as .62mbps). So I had them come back and they tried all kinds of things, only to discover Internet Explorer gets 50mbps, so it's something with Foxfire. What would it be?

  Hello, when you use speedtest.net or a similar site based on flash to measure your connection speed, it could be a problem with the protected mode that adobe has implemented for its flash plugin for firefox. Some older versions of f-secure or report of trusteer are known to cause slowdowns with flash, or it could be something similar on your system that interferes (maybe security software that block/sandbox the container used for protected mode, etc...).

  as a solution, you could try downgrading of 10.3 flash (which is always supported) or Disable protected mode & see if that makes a difference.

• S50 satellite - B 15 P - Fans running at high speed and system crash

  Hello

  I have a new SATELLITE S50 - B 15, i7-5500U, 8 GB Ram, SSD etc., IV and v have some problems with it.

  for unknown reasons the CPU fan starts to operate at high speed, even if the temperature of the CPU hit is not 35%.
  It also froze about 10 times since I got it (April this year).

  The only way to make it work again would be me to hold the power button down until stop and start it back up.
  Once launched upward there is no mention of potential problems in the newspapers of events other than the forced closure.

  I just wanted to know if anyone else has experienced problems?

  Thank you

  Chris

  The only way to make it work again would be me to hold the power button down until stop and start it back up.

  Forcing order restores the fan activity and performance?
  Hmm it sounds like there must be some sort of system emits probably the bottom of some process locks the CPU and therefore increases the activity of the fan.

  You could start the the Task Manager and in the process tab, you will find all background applications that would appeal to the CPU.
  Click the CPU column to display all the processes of loading the CPU.

  However, you can also try to change the option of cooling method that is available in Windows Advanced Power options.
  Go to control panel → power options.
  Click here on the power plan that is currently in use.
  Then click on advanced power options and access the cooling method.
  Here you can change it from active to passive.

  

  In addition, you can decrease the status of CPU max at 90-05%
