  1. I would like to use waveform to log the digital output of 8 channels over a period of time. I currently manually record the output events for the 8 channels, but I would like to have the PC take a 100 ms measurement every 10 minutes and export this data to a new file every 10 minutes. Essentially, I would like to know if the waveforms software can automated run a measurement and export it to a tdms file every 10 minutes over a few days. Thanks
  2. In due course, it would be nice to have Mozilla Quantum compatibility. Just thought I would throw this out there....🤔 Mike
  3. Hello - trying to install waveforms on Ubuntu. Downloaded the .deb package but it has a myriad of conflicts and dependencies. Any help around? Thanks,

  5. Hello, I'm starting to work with custom scripts on my discovery 2 (with oscilloscope extension + probes). I'm trying to setup a measurement environment using the AnalogIn_Acquisition.py sample script. I have a power supply with output voltage at 4V. When I run the scope at WaveForms I get 4V reading, however, when I run the acquisition script I get 2.72V as average voltage. I also tried with the AnalogIn_Sample.py script and also get 2.73V. I wonder why such different results. Pictures bellow:
  6. Hi all, I'm trying to save data from an acquisition but I'm not getting it. I mean, I want to document my tests and measurements. So, I wish to save the data in a way that I can later open it in WaveForms and navigate the capture. For now, I have only image but this does not help much. Does anyone know if WaveForms supports it? Thank you, João Paulo
  7. My Analog Discovery 2 was very sensitive to movement, with Waveforms reporting the connection lost at the slightest bump. Merely manipulating the flywire leads was enough to cause a disconnect. I determined that the plug on the USB cable that came with the AD2 was not able to seat completely into the AD2's USB jack. While looking through the top of the AD2's enclosure at the USB jack, I observed that the two metal "spring fingers" atop the USB plug were not inserting deeply enough into the jack to permit them to raise and latch into their corresponding holes in the top of the jack.
  8. Hello, For one of my school projects we were asked to find the minimum signal that will give a signal to noise ratio of 10 dB. How would I go about finding this? I know that the Spectrum Analyzer for the Analog Discovery would be used but I am unsure of how to find the signal to noise ratio of a signal. Thank you, cjobi247
  9. Hello, I'm a newbie using the Analog Discovery (Legacy), and attempting to run through a few experiments. When using the Power Source or "Supplies" tool in Waveforms 2015, all the directions and manuals show a dropdown menu where you can adjust the voltage (0-5V). The manual from Digilent's own website SPECIFICALLY regarding the Analog Discovery Legacy shows this as an option as well. I can't find any such option however in my program, it just isn't there. I should mention that I am powering the AD itself via USB from my laptop, but I don't think that is the issue as according to the

  11. Running 64-bit Ubuntu 16.04 and having trouble getting the .deb file to work to install Waveforms 2015. When I open the .deb file and click install, I see a progress bar briefly (<1 second) and then it disappears and the installation process doesn't start. Is this an issue on my end or with the .deb file on the website? Thanks edit: Having the same issue with Adept 2
  12. Hi folks, I'm currently hacking a 433Mhz temperature probe, and attempting to intercept the reading using a standard 433Mhz receiver, such as the Sparkfun RF Link Receiver. Using WaveForms (desktop) I can record the Logic Analyzer output, and can see the single fine. I'm currently in the process of parsing the bit stream. The signal is repeated every 59 seconds. However I need more samples, and the manual translation of the square wave to 0/1's is tedious and time consuming (and error prone). I'd like to create a script that will read the 'repeated' (not recorded, realtime) Logi
  13. Hi Dear Digilent Team, A question concerning the measurement capabilities ot the Analog Discovery 2 and WaveForm software: Is it possible to measure continously and "without losses" a frequency of an analog or digital entry? Goal is to log a frequency over a long period of time between EACH following flanks Optionnaly also measure times between flanks of different channels Examples: - Measure the freq/time between each following rising flanks of a channel - Measure the freq/time between each following falling flanks of a channel - Measure the freq/time between each fol
  14. Dear Digilent, I've been exploring the 3.6.8 features and love the impedance analyzer. What's the schedule for updating the Waveforms SDK and its Reference Manual? I'm very interested in automating some impedance measurements using python. If this has been done already, I apologize for not finding and asking this question. Thanks for the awesome tool. Craig ps. here's my video I created a couple days after 3.6.8 release, Analog Discovery 2 Impedance Analyzer, OPTs and What Tube Plates Really See!!!
  15. Hi , Is it possible to sweep up the frequency then down in a continuous run ? like sweep the frequency from 5 kHz to 100 kHz then back to 1 kHz. regards
  16. I have been using my Analog Discovery to measure output signals from a 3-axis accelerometer (Adafruit ADXL377) during an impact test event. Being a 2-channel device I have to first measure the X+Y outputs then repeat the impact event measuring the Y+Z outputs. I export these data then use a bit of Python code to combine two tests into a single result whereby I calculate the total acceleration by summing the squares of each axis (X+Y+Z). I trigger the scope off the Y-axis and make the assumption that the Y-axis acceleration is the same in each of the paired impact tests (which seems a reason
  17. I'm confused ... should I be downloading and using waveforms2015 or waveforms? waveforms2015 seems to be the name of a program that is two years out of date, however @jpeyron just recommended that this is the newest version of the waveforms software. Am I missing something? Thanks! Dan
  18. In Waveforms 2015, is it possible to set up a wave in the AWG to be triggered by every other pulse in the scope? I'm currently trying to use a 10 Hz external pulse connected to the Analog Discovery's scope as the trigger for a 5 Hz waveform from the AWG, but I need to have the event trigger only once the 5 Hz waveform has finished one pulse. Effectively, I'm putting together a slower trigger for one device that's triggered from the AD's scope using a faster external pulse. It appears that Waveforms 2015 has some logic capabilities incorporated into the software, but as I don't have a back
  19. Hi, I'm trying to use the Analog Discovery 2 to control a stepper motor driver board. All I need to do is send an output (5V) signal using a DIO. I find the Waveforms 2015 manual to be lacking in terms of documentation for this - it does not explain how to give an output signal. How do I do this? Thanks! For instance, the reference manual has this sample code: function doStaticIO(){ print("Running StaticIO script"); StaticIO.Channel0.Mode.text = "IOs"; for(var c = 0; c < 8; c++) { StaticIO.Channel0.DIO[c].Mode.text = "Switch"; } But
  20. I seem to be having trouble getting the AD2 to trigger on a repeated pulse. If I trigger on the edge of DIO 7 then it triggers OK (see logic_trigger_simple), problem is that power up sends spurious signals sometimes and so I'm tring to pulse on the counter. I have the counter set up as the other screenshot but it just will not trigger like that. There is no reset so I've set reset to DIO 15 which is unused and tied to ground. How can I get this to trigger on the number of pulses. Also, in the protocol triggeringl, is there any way to trigger on a sequence of hex val
  21. Hi all tagging some experts @jpeyron @attila Thank you for all the help in previous questions! From what I have gathered up till now is that I cannot access the protocol analyzers since they are at the application level and are not exposed to the SDK. However in my application I need a protocol analyzer along with the analog read of the AD2 simultaneously. (attaching previous post) So my only hope is to make a custom protocol analyzer to get the logic bitstream from the digital pins along with the raw waveform data. I tried to do the same in the code snippet attached. Howe
  22. Hi, I am using the Waveforms APIs to process the raw waveform data from the oscilloscope of AD2 to a C++ code. My other requirement is to use the logic analyzer simultaneously to get the data bit stream of data as well. 1. I was able to do this on the Waveforms 2015 GUI but is it possible using the APIs? 2. There are analyzers (SPI, I2C, Serial, CAN etc.) present in the Waveforms GUI, but is there a preset to do the same in the API? (not just being able to read 0/1 but analyse the SPI/CAN bus) Thanks, Shabbir
  23. Hi I am trying to install waveforms to use the analog discovery box. I am in Linux using Ubuntu and I have downloaded both adept and Waveforms and tried installing both using the terminal and everything seems like it installed but when I search to open Waveforms I can't find it. I'm not sure what is wrong or why they are not installing properly. I'm using the 64 bit for both. Please Help Thanks
  24. Hi all, The Waveforms program installed on my 64bit, Win 10 Laptop fails to connect correctly to the Digilent devices. I have tested with an Analog Discovery 2 and Analog Discovery, both were tested in other PC's so there is no external hardware issue. As shown in the attachment, Waveforms is reading the S/N from the device and current draw is within the expected range. My best guess is that there is a USB driver issue, what are your thoughts?
  25. I have been trying to set up the Waveforms Labview toolkit. But it seems that the driver is not compatible with my version of labview (pro 2016). Is this correct? I really need this to work with my version of Labview. Update: I also just tried it with Labview 2014 Pro, with the same issue.
