• myRIO ADC problem: side affacted channel of its previous channel

  Hello

  I use several channels ADC myRIO now and facing a question about it.

  I use 3-channel ADC Port A: AI0 AI1 and AI2.

  I have connected AI0 in the middle of a potentiometer for voltage accoss it. And connect anything to AI1 and AI2.

  CDA works very well. I can move the potentiometer valtage perfectly AI0.

  However, when I changed the value of the potentiometer, the CDA of AI1 and AI2 results changed also, 0, 1V to 0.8V about. Please note I have nothing plugged in these two ports.

  Is this true? the ADC AI1 and AI2 and AI3 same (PORT A) port are affacted by AI0?

  When I connected AI1 to an Anolog output senser, the result was also affacted by the potentiometer which was connected to the AI0.

  When I connect AI1 in power, he was out of influence.

  Did someone already had such a problem? Can someone help me to solve it?

  Thank you

  It is the response of support OR:

  Please note the small change you notice when both of your strings are attached can be due to several factors such as the wrong wire shielding, etc and EMC (electromagnetic coupling).

  What is a floating channel terminal, random or variation is normal and due to internal correlated myRIO circuits and should not be a cause for concern.

  Well, I'm still very confused.

• mcb2300 (lpc2378) SPI and external ADC

  Hello

  I use LabVIEW 2011 Embedded for ARM in collaboration with MCB2300 Development Council and MCP3204 12 - bit ADC chip. I try to use the base screws of SPI to communicate with the MCP3204. I enclose below the screenshot of my VI. Can someone tell me if this is a way of thinking? I would like to read the data from all 3 channels of ADC - 3 axes of the ADXL sensor connected. In addition, I have attached a few pages of the MCP3204 datasheet.

  Thanks in advance

• The NI USRP-295xR RIO allows a front-end Ettus BasicRX IF-sampling? And what is the rate of the ADC to FPGA data?

  Hello!

  I'm in the quest to replace some aging PCI-5640R. I am currently using as a portable-Journal data solution, mounted in a Magma Expresscard to PCI box with a laptop. As a reference of the time, I use a Symmetricom XLi.

  The equipment is dependent on the sampling finished a set of samples once a trigger signal goes high and also receive antenna azimuth information using two lines PFI more. The signal is sampled at IF, 30 MHz, and the signal is less than 5 MHz bandwidth.

  Now, I started watching the Ettus X 301 with a GPS OCXO and MXI-express interface which should be the same as the USRP-295xR NI. It is available as device NI RIO with three different front ends, unfortunately, none of them work at 30 MHz.

  Q-1: Ettus has the front-end 'BasicRX', but it is only considered compatible with LabVIEW driver and not necessarily with the RIO. Is the front-end BasicRX usable with the USRP - 295XR RIO and MXI-interface with LabVIEW FPGA? Should I just avoid trying tune the nonexistent LO? As long as he gives me data, I can live with some error messages during the Setup...

  It's the best solution for me, but if it is absolutely impossible, I have a few questions:

  Q-2: information on the front end are really rare in the pages Web OR both Ettus, but the WBX is listed up to 50 MHz frequency, to have a filter of low pass of bandwidth of 40 MHz to I and Q. This should mean a total of 80 MHz of bandwidth with I and combined Q,-40 to 40 MHz. Why did the bandwidth to Web pages as OR listed being "40 MHz bandwidth in real time", if the low pass filter of the WBX is 40 MHz in I and Q? Not the band total bandwidth or 80 MHz?

  Q-3: assuming a bandwidth-40 to 40 MHz: could I put the WBX LO at 50 MHz, be tuned to the frequencies from 30 MHz to 20 MHz signal,-20 MHz and use a bandpass filter to the FPGA to extract the new signals and remove all other signals?

  Q 4: I tried to start a FPGA project in LabVIEW and add the x 301/294xR/295xR as a target. Data clock is locked to 120 MHz, which I guess means he will receive no data to 120MS/s IQ? The x 301 Ettus is listed as provide data of the ADC to the FPGA at a rate of 200 ms/s, could someone explain to me why, OR USRP RIO expects only database 120MS/s?

  Hi Idar,

  Yes, you should be able to put the basics on your X 310/USRP RIO and use LabVIEW FPGA to receive 120 MECH. / s of the DACs.  The example I posted is in fact not for the precompiled file bit.  The example I posted is for LabVIEW FPGA, which allows you to add the IP address for the FPGA.  There is a sample project that comes with LabVIEW FPGA which is the recommended starting point to build your FPGA application.  The sample project has all the configuration set up as well as broadcast continuously and pads/FIFOs in the FPGA and examples for synchronization.  There are comments in the code example that show where he must add your own blocks of property intellectual as a filter and decimater you mentioned.  The PDF I posted shows what changes you must make to this sample project using the Remora Basic/LF.

  I would like to know if I'm not explaining this clearly, or if you have any questions, I'd be happy to help you!

• Improvement of the aquistion of ADC pulse time

  Hello

  I use Labview 8.6 Professional version and an ADC NI PXI-5114 in a chassis PXI-1033 to capture some positives.  The pulse widths are in the order of 100 ns to 10.  The impulses can reach CDA at random times.

  With the search here, I found some suggestions very useful and therefore following the examples of Labview OR-Scope my Foundation, I managed to set up a program that allows you to capture these impulses.  For now it works great except for one thing.  It will not capture consecutive pulses that are closer than 2ms.  It is too slow for my application, actually faster than I can be ready to seize the next pulse best.  If I can get this time back down to about 200 US, I'll be happy.  The ADC 5114 specifications indicate a time to rearm in the low microsecond range so I know the hardware is capable of doing much better that what I mean but this is translating to the software side of things gives me some difficulties.

  As much as I know there is no trigger to start and stop captures data on one edge, so in my program I capture of basic data on extraction into pieces and use a signal processing subVIs to pick up the trailing edge of the pulse in order to know when to stop capturing data.  If the pulse width has been set then this wouldn't be a problem, but as I don't know what it will be, I prefer to capture just the pulse so that I don't miss other legumes.

  Is it an inefficient way to solve the problem and what is perhaps originally the code is running slowly?

  I would appreciate any help with a solution to this time getting 'rearm' down (or comment on my code and that you feel would improve it).  I've been using Labview for a few years (only to learn as I go), but it's my first shot using NOR-Scope and a digitizer high speed.

  All suggestions are welcome!

  Thank you

  Daniel

  More importantly, if you want to rearm fast, deterministic, you must use multi-record acquisition.  This sets up the device automatically and very quickly (depending on the configuration and device, 1us to 10us), rearm.  As you apparently don't know how long the pulse can be at any point in time, you must set up the record for a reference position length small (say 10% for 10% pre, post 90% trigger) and samples sufficient to cover your expected worse (10us + 10% pre-trigger + a margin engineering for a pulse that is wider than expected).

  You can activate the multi-record acquisition by plugging in just in a number to Terminal "number of records" on the Horizontal VI to configure.  This will configure the digitizer to divide his memory embedded in N circular buffers to store individual records triggered.  It is the only mode that you can expect to get quick reset time on as host, recovery time, and duration of treatment are not the bottleneck.

  Once you do this, you will need to make a few small changes to the rest of your VI existing to control what (s) you are to pick up.  I suggest you look at the examples of Multirecord NOR-Scope.  If the flow is a concern, you probably want to fetch multiple records at a time.

• using several of the ADC (ad7476a) via SPI

  Hello:

  I BF537-EZkit and AD7476A-GERD and I set to work using the project "SPI and UART.

  But in my project, I have to AD7576A several... How to configure the SPI to do this?

  I used the "analog s in reading" loop inside the moment (who writes via UART), but he reads the ADC too slowly for the reading of the AC...

  What is the correct way to do it? The UART is useless I use it just to see the values read by the ADC...

  Thanks in advance,

  Antonio Freitas Verissimo

  Hello

  To control the operation of the multiplexer, you can use a digital output of the Blackfin. You can use the PPI on the Blackfin to do. You will be able to control in LabVIEW with functions at Black fins that have been added to the palette for LabVIEW.
  If you are not familiar with LabVIEW, you can learn here:
  http://digital.NI.com/public.nsf/allkb/7D5F60ADBFD9CDC2862572BA005DD96A?OpenDocument
  Besides, the exercises provided with the EZkit should help ( http://zone.ni.com/devzone/cda/tut/p/id/6949 ).

• Help with the NOR-DAQ example Code

  Hello. I just started to work with the NI IBS-6211. It's the first ADC I have ever used, so I'm farily to this news. I have some programming knowledge. After a search in the installation files, I found some examples of C Code that runs in the command prompt. I changed an a bit to get it to do what I want. My question is...

  Now, I have a few problems. I am trying to print a voltage in the command prompt. I hooked up everything and I used labview to make sure that everything works as it should (it does!). When I compile the C program and the run, instead of returning a voltage that is just acquired points and I really have no idea what are these 'points '.

  Here is the main part of the code example:

  DAQmxErrChk (DAQmxCreateTask("",&taskHandle));
              DAQmxErrChk (DAQmxCreateAIVoltageChan(taskHandle,"Dev1/ai0","",DAQmx_Val_Cfg_Default,1.0,10.0,DAQmx_Val_Volts,NULL));
              DAQmxErrChk (DAQmxCfgSampClkTiming(taskHandle,"",10000.0,DAQmx_Val_Rising,DAQmx_Val_FiniteSamps,1000));
  
              /*********************************************/
              // DAQmx Start Code
              /*********************************************/
              DAQmxErrChk (DAQmxStartTask(taskHandle));
  
              /*********************************************/
              // DAQmx Read Code
              /*********************************************/
  
              DAQmxErrChk (DAQmxReadAnalogF64(taskHandle,1000,10.0,DAQmx_Val_GroupByChannel,data,1000,&read,NULL));
  
              printf("Acquired %d points\n",read);
  
  Error:
  

  And then he moves right down to the exit clause. Is there documentation anywhere that tells me what DAQ command should I use to print a voltage continuously updated reading? (As a decimal number, such as 5.21V for example).

  Thanks to you all

  John

  John,

  The data acquired by DAQmx are written in the array called "data".  The number of points DAQmx wrote in this table is stored in the variable 'read' which was adopted by reference in.  To print the values returned, you need to loop through the array of 'data' and print each value.  See this help topic for an explanation of DAQmxReadAnalogF64.

• Average of ADC signal

  Can someone help me find the way to a signal. I used simulate the signal function of sine wave with the freq of 100 kHz, sampling FREQ 500kHz and 1250 samples. I spent this signal to a 16-bit adc and found the digital waveforms. Now, I want this signal for 1250 samples on average. Can someone tell me how to proceed?

  Hi sanju,.

  have you noticed the message #2?

  Define the "D" in "ADC"! Generally, you will get a 'value' number of bits of the ADC (12/08/16 by value bits). The SimulateSignal will also give you values - and these values are averaged in my example...

• ADC signal formatting problem!

  Personal salvation OR.

  IAM having problems trying to measure tension in the port adc to a PIC 18F4550 through Labview.

  the fact is that iam like a beginner in programming G, and I don't know how to maintain the chain that iam get VISA read module and therefore iam does not receive the data in the appropriate form.

  IAM using an 8-bit adc, so I pretend to read the 255 when iam in FS. but iam get something like "48", as you can see in the attached screenshot.

  I thought about it. I don't know exactly why but it seems that the number of the indicator and all the conversion in takes only a part of what im sending.

  It worked simply by attaching a string indicator in the outpin of the VISA-READ. It was the first option I thought the first time, but it did not work this time.

  Sorry for the flight of your time and thank you for the help!

• Pico Tech Adc-212

  Hello

  Im having a problem with an exception caused when I use the "call library function node" for initializse my ADC-212 im not sure what else I can try.

  Thank you

  Gordon

  Exceptions occur mainly because the parameters you pass are of the wrong type of data.

  The example provided with labview

  C:\Program NIUninstaller Instruments\LabVIEW 2011\examples\dll\data pass

  does not give you much information about the different types of data.

  Hope that helps.

• Check an ADC with the PXI-6259

  I use the PXI-6259 M Series DAQ in LabWindows/CVI ADE, and now I want to check if a 8-bit ADC works properly or not.

  The entrance to the ADC is a sine wave and I acquire the 8 bits of data (in Digital Format or Port) every time that the A/D conversion is complete. Then, I want to regenerate the sinusoidal wave with digital data using 6259.

  The analog channel supports only the numbers to decimal floating 64-bit data format but not Unsigned and data format signed integers, have of I scale digital data acquired for floating-point numbers 64-bit data format according to the amplitude of the sine wave and then regenerate the waveform?

  If so, I have to Brown the APFI0 or the APFI1 as the DAC reference voltage source?

  Thank you very much for your help.

  Done writing DAQmx supports the signed and unsigned writings. Open the library > NOR-DAQmx > write functions and find DAQmxWriteBinaryI16, DAQmxWriteBinaryU16, etc.

• Gel system and random blue screens of death, help!

  Hi all

  I'm hoping to get help with my system. TI all started since I installed a new video card, or at least, that's when I think it all started. I went to a Nvidia GTX 260 to a 750 from Nvidia and the problems seemed to start from there.

  Since I put the 260 in however problems only got worse.

  I scanned my system for malware, and I also ran CCleaner without result.

  Here are my system specs:

  AMD processor with Six cores (tm) - 6100 FX 3.30 GHZ
  RAM: 8.00 GB

  Windows 7 Home Preemium - SP1

  64 bit

  On the BSOD I became IRQL not less or equal, but has not been able to take a picture of it in time. I also got planner of video with BSOD, memory management. (See attached pictures)

  As I said before I'll sometimes get a BSOD but the system just hangs and what is on the screen will just stay there and nothing to move or respond to all.

  I also ran memtest86 and took photos of the results after an hour, eight hours and 24 hours. (See attachment)

  I uninstalled and reinstalled several times video card drivers thinking that could be the problem, but it does not solve too anything.

  I'll post my files minidmp in a few minutes.

  Here is the link to photos of the errors. http://share.PHO.to/4tTvj

• Need help to find an adapter for a third-party monitor

  Hi all! I find myself in need of a little guidance, and I hope that someone out there will have a quick n easy for me...

  I have a Mid-2011 27 'iMac. which has two ports Thunderbolt It is taken with a Wacom tablet that I use constantly, and the other is made by an external hard drive to a solid state, which has a built-in cable to Thunderbolt (no way to hang it on a different port). I also have a 27 "HP monitor that is currently connected via an HDMI USB adapter.

  The problem is that the HP monitor is actual "jiggy" - the USB does not seem fast enough to deal with requests for the monitor. It is almost unusable. I know I should run it via a HDMI adapter Thunderbolt, but as I have already mentioned the two my Thunderbolt ports are already in use.

  Someone at - it ideas? I need sort of three to two ports Thunderbolt hooks, but I can't seem to find anything for less than $300 that would work. (I am illiterate when it comes to the different cables, adapters, ports, etc., so I hope someone can point me in the right direction by using short words... Most of the products that I travel through list specifications that me Chicane).

  The monitor has two HDMIs and a VGA port, and my iMac has a Firewire 800 port, if that helps at all...

  2011 iMac have only 1 Thunderbolt port and there is no such thing as a Mid-2011, you must have an iMac of year later, if it has 2 ports Thunderbolt. All the 27 "iMacs, from 2012 to 2015 the current have 2 ports Thunderbolt.
