• NEITHER USB 6008 AI acquisition and generation of pulse

  Dear users of LabVIEW,

  Greetings for everyone. I am a beginner of LabVIEW and I have a problem that I solved partially. I would really appreciate your help and suggestions that I searched for days without a bit of luck. The problem is as follows:

  I am the acquisition of tension HAVE (continue) 4 to 8 accelerometers. In the meantime, I send you a digital output signal each time when you click on the sampling frequency (i.e. 1000, 2000, 3000,...) If the sampling rate is 1000). In other words, try to send a signal of output digital (at a frequency n Hz) at intervals of 1 second (depending on the material). To make the digital output signal begins to blink a LED every one second. In addition, I need to write signals (voltage) AI and the LED blink timestamps PC (software) separately. All stages of the above are followed in my .vi program, but the real hardware/software level operations kill my timestamps. In other words each LED flash timestamps are not accurate, when I use LabVIEW measurement file express VI (the difference is not at least to the third decimal). In addition, the timestamp is kinda OK when I disable the file LVM write VI. Onemore thing I've noticed is that physically the LED blinks every second two times, I feel it's because of the shift register and loop delay of a second. Is there a way to control the speed of blinking (i.e. Boolean State must change to every 500ms without delaying the inside while loop).

  Results and comments:

  LabVIEW 2011 .vi, timestamp of files with or without generator of LVM (express VI) files are all attached. Please note that there is a considerable amount of drift in the consecutive timestamps when the file LVM generator is used, on the other hand there are derivative of 0.001 ms when the file LVM generator does not. The reason for horodateurs PC have is about aligning the various measures or observations or events to global time scale.

  Please give me any suggestions or help me do at least accurate to milliseconds in VI of witten. Finally, is there any USB DAQ module relatively inexpensive which allows to send an impulse to directly from channel impulse of output digital channels when the "n" sampling frequency Hz is obtained by level of material which could all be accurate, so that the software timer is completely reduced to a minimum. Although there are very material sophistiated of NOR, but our goal of this project is to build and test the system profitable.

  Thank you and I really appreciate your time and effort inavluable. Have a great weekend!

  Just change the samples to the constant playback at the entrance of the DAQmx Read.vi from 1000 to 500.

• acquisition and generation of signals synchronized redpitaya impetus

  Hi, I'm new in collaboration with redpitaya and labview.

  I've been trying to get the example of the "generation of signals a synchronized pulse and acquisition" has worked with labview. But I have a few problems.

  FISLY, when I downloaded it, some varibles where the wrong type, so connection could not be made (fig. 1). So I use a block converter (from string to number) in order to solve this problem, because he wan't work I changed directly two of the entries from string to number and I kept the conversion of the rest of the string variables (picture 2).

  I was getting an error, but the example did not work properly. When I play run, it only resgisted noise, but not the signal that it was created (image 3). I changed the table (chanel I used, amplitude, frequency, the shape of the signal itself)
  To check that the wire and the RF input and output was OK I tried to change the signal, put it on my hand and the change in signal to noise, but there was still noise (picture 4). I tried each entry and exit, but I still have the same signal: noise.
  To conclude: I can't do this example to work.

  In addition, I have a question on this example, the labview and Redpitaya libraries: How can I change input 1 input 2 and from exit 1 to exit 2, because I don't see that option 1 of chanel and chanel 2, but it does not say what combination of input and output is. and I can't find the block to edit entries and exits

  If anyone has had the same problem, how to solve it?

  Thanks in advance!

  Entries you 'fixed' are not numbers, looks like they are channel names. The representation has changed some time ago, but it is an example of the former.

• Continuous data acquisition and real-time analysis

  

  Hi all

  It is a VI for the continuous acquisition of an ECG signal. As far as I understand that the analog read DAQmx VI must be placed inside a while loop so it can acquire the data permanently, I need perform filtering and analysis of the wave in real time. How I implemented the block schema means that data stays int the while loop, and AFAIK the data will be transferred on through the tunnels of data once the loop ends the execution, it clearly isn't real-time data processing.

  The only way I can think to fixing this problem is by placing another loop that covers the screw scene filtering and using some sort of registeing shift to transmit the data in the second while loop. My question is whether or not it would introduce some sort of delay, and weather or not it would be supposed to be the treatment in real time. Wouldn't be better to place all the screws (aquicition and filtering) inside a while loop? or it is a bad programming practice. Other features I need to do is back up the data I na file, but only when the user wants to do.

  Any advice would be appreciated.

  You have two options:

  • A. as you said, you can place the code inside your current while loop to perform the treatment.  If you're smart, you won't need to put one another while loop inside your existing (nested loops).  But it totally depends on the type of treatment that you do.
  • B. create a second parallel loop to perform the treatment.  This would be separate processes to ensure that the treatment is not obstacle to your purchase.  For more information, see here .

  Your choice really depends on the transformation that you plan to perform.  If it's much the processor, this could introduce delays as you said.

  I would recommend that you start at any place in the first loop and see if your DAQ buffer overruns (you can monitor the rear of the buffer during operation).  If so, you should decouple the process in separate loops.

  In what concerns or not ' it would be considered as real time processing ' is a trick question.  Most of the people on these forums say that your system is NEVER in real time because you're using a desktop PC to perform processing (note: I guess it's the code that runs on a laptop or desktop?).  It is not a deterministic systemand your data is already "old" by the time wherever he leaves your DAQ buffer.  But the answer to your question really depends on how you define "real time processing".  Many lay it will set as the treatment of 'live' data... but what is "actual data"?

• acquisition and generation of signals

  Hi all!

  I'm new to labview and I need help. I am trying to acquire and generate data to two devices simultaneously. I reached successfully synchronous acquisition, but the problem I have is that whenever I run the program it is not compatible. Can someone help me and take a look at my code?

  
  

• Counter the acquisition and generation of simultaneous signals of Daqmx triggered

  I am writing a vi that collects the data of a specific length (1000 points) when writing the data of the same length on another port on the same card (PCI-6052e). Collection and production are both triggered by a pulse of a counter on another Board (PCI-6711). I am able to trigger both successfully, but not at the same rates and not to the desired resolution. The generation of waves and the collection forms should be 8 msec in duration. I have attached the screws. Any ideas would be appreciated.

  Thank you

  Jordan

  Eventually clocked continuous generation, but the displacement of the wave write vi DAQmx out of the loop (just before the beginning of vi), and this fixed the calendar.

• Excerpts from continuous data acquisition

  Hello

  I want to make an acquisition of continuous data with a NEITHER-6133 @ 1ms per channel. The data must be stored on hard disk. At the same time, I want to take excerpts from acquisition to calculate different values. The acquisition of the extract must be triggert by an external digital trigger.  Are there examples, which combine continuous data collection and collection excerpts?

  Thank you very much.

  Best regards

  Michael

  Thanks to the support of NOR-Germany, I found a solution for me:

  1.) continuous trigger switch

  Connect 2) the trigger for the signal to a digital i/o

  3.) synchronize AI and DIO

  Excerpt 4.) the samples needed by the search within the digital waveform pattern

  Result:

  The example shows 4 IA channels Cup (tested on Win7, NI PCI-6115, 4 channels each 5. MECH / s) and calculation on extracts from each channel signal triggered parts.
