  1. I am using the AD2 on LabVIEW with dwf.dll. I am using the I2C interface on DIO bits 0 and 1 and the positive power supply. I have configured everything based on the python example code. When I set the power supply and write the I2C data, several other DIO bits go high even though they are not configured in this program. I have auto configuration enabled. I can do the same thing in WaveForms and it works fine. Any suggestions would be appreciated. Thank you
  2. Hello, I am building an SPI proof of concept for the Analog Discovery 2 in LabVIEW and I am unable to get the entire thing working, despite other successful LabVIEW projects that use the Analog Discovery 2. The issue I am having is that I am capable of generating an SPI message output where the AD2 is the master, but I am unable to get the expected response in the Rx array. The pinout is the clock is on pin 2, the chip select is on pin 1, the MOSI_SISO is on pin 4 and these three outputs are connected to an oscilloscope for observation. The MISO is on pin 7 and is connected to a pu
  3. We're excited about using the AD2 for a whole bunch of courses in our college as we teach online for the foreseeable future. One useful feature would be if we could get the raw A to D data from the scope channels so we can use them in LabVIEW. At this point, niVB_MSO_ReadAnalogDigitalU64 provides the voltages, all cleaned up, instead. Is there another dwf that provides the raw data, or could this feature be added to the next revision? At this point, I'm taking the voltage and converting it back to a step count using the step size, but we'd be just a bit more accurate if we had the raw
  4. Hi! I want to read the output data of a delta-sigma modulation based ADC (AD7402) using NI LabVIEW FPGA. Can you help me by explaining what the Verilog code in the attached datasheet (page 17) does? AD7402.pdf
  5. I am trying to get my Analog Discovery 2 to work with NI LabVIEW 2019. I've searched around and most of the info I see calls for LabVIEW 2014, so it is not clear to me if it does or does not. I have installed the AD2 Toolkit and the Digilent WaveForms VIs. My problem is what is the "Device Name" that need to be entered? I see the AD2 with the WaveForm 3.13.10 x64 using Windows 10 and full LabVIEW 2019 x32. Thanks for shedding any light on the situation. JoeD
  6. Hi, I am using your driver Analog Discovery 2 in Labview 2017. Trying to run a sampe I can't receive the results I expect. the setup is : sample rate of 7.692M wiht 8192 samples - trying to use hight rate or no. of smaple returns an error. Here is attach a picture of the case. Could you send me some information how to fix and have the wave as the example in the picture ? AD2 Analog Example(Multiple).vi
  7. I need to control a device, using LabVIEW to give command to signal generator(Agilent 33522A), which can make the device switching voltage(amplitude)with short time(10~50ms). I have a problem: Where to put the time command to make the time can be adjusted? Or indicate whether my code is proper for my requirement. Agilent 33522A Control_2.vi
  8. Hi all, I use Analog Discovery 2 to generate a ramp up waveform and observe synchronously the response in the scope. The wavegen output W1 is wired to the scope input Ch.1. I want the scope to be triggered by the generated waveform, so that subsequent acquisitions yield signal that starts exactly in the same moment. I attach the VI that I have made to achieve this (testscope3.vi). I use Configure Digital Edge Trigger.vi to set up triggering. What I expect is that on each loop repetition the acquired signal would start in the same moment, but this is not the case. Each acquisition starts a
  9. Hello, I am working on a project that uses the Analog Discovery 2 to measure the response of a DUT over a long period (hours or days). I am working in LabVIEW and have been building this project using the foundation provided in the LabVIEW project shared here. It uses both the Waveform Generator functionality to apply a signal and the Scope functionality to measure the response. Currently, I am running into a problem where my code stops working after 250 minutes. It seems to be very consistent. I and another have replicated the issue using multiple AD2 devices, multiple PCs, and
  10. Hello, I need help creating a VI on labview to read the gyroscope on the Pmod Nav. I have Linx and the Pmod example files but none are for my specific Pmod. I have the Pmod connected to a arduino uno and using Linx for the interface between the two. I can't find any examples on how to make one for this Pmod or make a custom VI for it. Help will be appreciated. Kind Regards, ARD1996
  11. Hi guys: I need know how create a Custom Command in LINX for read a encoder of two square pulses from the digital pins of Arduino in LabVIEW. Thanks.
  12. I am using Raspberry Pi 3 with raspbian jessie and installed labview 2014(32bit) in my windows 7 laptop. Everything goes smoothly as I connect to my rpi using the linx target configuration. The problem is that everytime deploy a vi (I deployed blink), i get this: Initializing... Calculating dependencies... Checking items for conflicts. This operation could take a while... Preparing items for download. This operation could take a while... Deploying NI_PtbyPt.lvlib Deploying LMH-LINX.lvlib Deploying LMH-LINX.lvlib:Local IO.lvlib Deploying LMH-LINX.lvlib:Device.lvlib Dep
  13. I'm working on a university project and I've programmed the stepper motor on LabVIEW and am using the digilent motor adaptor but the signal leaving it doesn't seem to be right even though the labview control is correct in the signal that it's giving it. It can run up to 30rpm but then it stops and doesn't run. I have run out of ideas and think the error must be generated from the connections in the motor adaptor but I have no idea why as the connections seem simple enough. Has anyone done it before and have a ready made program for it. This is the program I am using at the moment. Main.vi

    hi, can you help please what digilent hardware you offer for digital datalogging (on/off, date/ time stamp, txt file(?)) and for easiest access to Labview thru lan? thanks, sandor
  15. Data Types Data types indicate what objects, inputs and outputs you can wire together. For example, if a switch has a green border, you can wire a switch to any input with a green label on an Express VI. If a knob has an orange border, you can wire a knob to any input with an orange label. However, you cannot wire an orange knob to an input with a green label. Notice the wires are the same color as the terminal. The dynamic data type stores the information generated or acquired by an Express VI. The dynamic data type appears as a dark blue terminal. Most Express VIs accept and/or return t
  16. I have an Analog Discovery 2 and am using Waveforms to test circuits, measure voltage and current, model protocols such as I2C, SPI, and CAN. What would the home edition of Labview do to help me? Thanks
  17. Hi, I have designed an UART core without any flow control for use with FPGA devices when communicating with LabVIEW. I am looking for a way to receive (from FPGA to LabVIEW) data fast and correctly, hence I am investigating the following configurations for setting the VISA READ when to start or stop reading UART bytes: 1-with termination char: this is very tricky in the binary world as are the FPGAs, because it can trigger false stops sooner than expected. A solution will be to use a custom 3 termination chars like "/n/n/n" and LabVIEW will read till will receive this sequence.
  18. Hello, I am working on a project that involves using the digilent analog discovery 2 to act as a an input and output for a VI in LabVIEW. I have downloaded the Adept and Waveforms software to communicate with the discovery 2 and LabVIEW. In this VI, I am getting an error number 1097, which has to do with the call library function. The error is in an attached photo. I have tried the suggested fixes online but have not found one to work for me. The error does seem to occur at the sub-VIs I downloaded from National Instruments, built to work for the discovery 2 in LabVIEW. When I open the ca
  19. I need to make a UI on C#.NET or LabVIEW and wirelessly(WLAN) speak with an communicate with an application for hardware control running on linux fundamentals based Single Board Computerr. What is the best and simple approach to complete it? NOTE: linux based application will be written in C/C++.
  20. Hello everyone I am trying to interface the Pmod Gyroscope with myRio with the code provided in the myRio Project Essentials Guide. I have made connections as per the diagram in the guide and there is no problem with it. When I run the VI, when the sensor is stationary the value of x displacement should be zero and not change but it is incrementing with time even when I am not moving the sensor. You can check the problem in the YouTube link I have shared bellow. There is no problem with the hardware since I have tried the same program with other gyroscope of same IC. The program file
  21. Hello, I am getting successfully data from an accelerometer and I then I want to calculate the frequency of a vibrating object where the accelerometer is placed at. As you can observe in the attached VI after I obtain the accelerometer measurements I use data queue function in order to collect a certain amount of data(200), in order to have enough samples for my FFT. Then I use build waveform function and at the end filter and spectral measurements vi. But unfortunately I do not thing that I get the frequency I want.And that means not only that the x axis in waveform graph is not
  22. Hello, I am trying to get x,y,z axis data from the accelerometer adxl345 using linx in labview. I have managed to do that with I2C protocol, but I want to do it also with SPI protocol in order to achieve greater sampling rate. I have read the adxl345 datasheet but I struggle figuring out to which exact registers I must write so that I can read the datax,y,z registers. I attach my -so far now working- program below, thank you in advance. adxl345spi.vi
  23. 64 Bit LabView 2017 DLLs are not available anywhere. 32 bit DLLs all generate errors. Is there a solution for this? Best Regards... Kamran
  24. Greetings, Is there a toolkit, etc. for use with the AD2 and Labview for I2C or SPI? I would like to monitor and simulate if possible. I have download and looked at both the Waveforms toolkit and AD2 toolkit, but did not immediately see this functionality. I'm guessing no such bundled library exits. Thank you Cheers, JMA
  25. Waveforms is excelent for setting up data Collection, recording data and save to file. To analyze the data I want to use LabVIEW. Is it possible to read the aquisition files stored by the Waveforms software from LabVIEW? I am using the Analoge Discovery 2 Scope function.
