  1. I am unable to make Waveforms working with my Analog Discovery on Linux. I installed Adept 2 and Waveform, when I plug my device in the usb port I have it recognized. It seems it is Waveforms that refuse to recognize the device or something bad happen as soon as I start Waveforms to the USB connection. Here is the log output when I connect the device in the USB port: oct 06 20:49:09 feynman kernel: usb 2-1.7.4: USB disconnect, device number 11 oct 06 20:49:09 feynman dbus[1324]: [system] Activating via systemd: service name='org.freedesktop.Avahi' unit='dbus-org.freedesktop.Avahi.servi
  2. Hi, I am working for an instructional laboratory where we have a number of the Analog Discovery devices that we are using as oscilloscopes. Our primary issue is triggering? We have some experiments that require at least three scope inputs and a waveform generator. We are trying to get two of the devices to sync nicely with each other using the in/out triggers, to trigger two scopes simultaneously. Much to our surprise, we found that the wavegen trigger out, is simply high when running and low when it is not as opposed to the standard TTL sync out found on most devices. Is there a
  3. Hi, Long post warning! Short version question: When using FDwfDigitalInTriggerPositionSet and FDwfDigitalInTriggerSet API functions, is the first sample coincident with the trigger or at the next clock (divided down) tick? I am using the Analog Discovery Board to implement a SPI master interface in Python. I essentially married two examples which come with the SDK: and DigitalIn_Acquisition. It supports both options for CPOL and CPHA. The problem I am facing at the moment is that CPHA=1 is unreliable. It seems that I am not configur

  5. I've been experimenting with a Analog Discovery system controlled via Python and have determined how to generate a digital signal out, however I have not been able to have the signal change frequency or duty cycle mid run. I have tried just use the function that controls duty cycle a second time however that just seems to overwrite the first. Below is the python code I have been using, any guidance would be much appreciated. -ZG """ DWF Python Example Edit ZG Requires: Python 2.7, numpy python-dateutil, pyparsi
  6. I am trying to download Waveforms 2.9.4. I am logged in to When I right click on the blue Windows icon and click Save As, I get a message "... couldn't be downloaded". I am using Windows 7 and IE11. Yes, I am trying to download the legacy version, I do prefer it. Any ideas as to what I am doing wrong?
  7. Hi, I am using an analog discovery to record relay trips. The goal is to record voltage a set time before the trigger and a set time after the trigger. i am writing the average and time to an array and saving the array to a csv file once the after trigger is complete. currently i am using the default script that comes with the program. it works and i get the information but the time stamp using Date() gives hh/mm/ss and i need smaller units of time. My question is: How can i get an accurate time stamp using the script? I need to maximize the number or samples i can take so
  8. I'm using Analog Discovery 1 with Waveforms 2015 3.3.7 (64-bit) and trying to get the UART decoding to work for me. My serial settings in my test apparatus are 115200 baud, 1 start bit, 8 data bits, no parity, no stop bits. When I send 0x55 (01010101b), it appears to decode properly as shown in the image below: If I send 0xAA (10101010b). It gets confused about the start bit and the first data bit (i.e. two 1's right next to each other) as shown in the image below: I tried forcing the decoding to start at the appropriate place with the "Start UART from here" fea
  9. Hi I want to record approx 50-1000 us long square wave signals from a separate waveform generator with Analog Discovery (Portable Analog Circuit Design Kit) via Matlab. The official Matlab code for recording with an Analog Discovery does not work ( Instead, the program is continuously busy when executing startForeground(s) and does not produce results. The official Matlab code for waveform generation and acquisition at the same time (
  10. Hi, I am trying to figure out how to use either ScanShift or ScanScreen acquisition mode for Digital Inputs into the Analog Discovery. And well, I can't get it to work, and haven't really been able to find any information online. My overall goal is to be able to stream out the digital data, so that I can capture and store more (continuous) data than the 16 kB buffer size. This doesn't have to run fast, I need to capture at 10,000 samples per second. The problem seems to be that the Digital In is staying in a "trigger" state. I am using Python, and using the function: dwf.FDwfDigitalInStatus(hd
  11. Hello there, I am using Analog Discovery 2 and WaveForms software. I was wondering either there is any way to export the scope view to pdf or eps format? Or any other vector graphics format. That would be great for papers. If there is no such feature, maybe developers would consider this option? I would appreciate all help.
  12. I would like to incorporate the Analog Discovery into a piece of equipment, but I cannot get it to work over a longer USB cable. In fact, sometimes I can't get it to work reliably over the short USB cable that is supplied with the device. I have tried all of the tricks suggested on the forum to no avail. I have also tried a powered USB hub. It appears that it will mostly only work with the cable supplied by Digilent. This makes the device functionally useless to me. I need to be able to separate the computer and the Analog Discovery by more than 18 inches. When I try to use a cable that
  13. Here is a summary of my issues, my Teacher's Assistant's response, and the results of further troubleshooting: --------------------- I am having trouble with what I would expect for some of the voltages in the H0-2 lab. I have successfully completed the first portion of the lab. Now I am attempting to measure the voltages with the voltmeter. I was connecting the + voltmeter end to the red power source and the -v end to the black ground. With the power supply on, the reading was about 2.76V. I thought this may be due to some resistance or bad wiring, so I directly connect
  14. Hello! I have a system receiving a sine wave of one of the analog discovery waveform generator channels. The sine wave changes when crosses the system and at the end, the modified sine wave is read by the analog discovery scope channel. The original sine wave starts at t=t0s but the acquitision only starts at t=t1s. I need your help to try to read, simultaneously, both the modified sine wave and the original sine wave. sAnjo
  15. Hello, I am new to the Analog Discovery and WaveForm software, so this might be a "silly" question. I did try to run some scripts in WaveForm3,0 (The latest version). Right now, I am just running the example code coming with the tool. It is shown in the following, it gave errors, like Can't find variable: Wavegen1, etc. I believe I have to add a library which includes all the definitions of this variables, but I didn't find them. Can anyone help with me and show me how to get codes like this to run successfully? Thanks so much! function main(){ if(!('Wavegen1' in this) || !('Sco
  16. Hi I have an analog discovery that has been working fine for the last 2 months. But yesterday i got the error message: The device needs at least 2W/400mA from USB Cable. I am running the Wave From 2015 app. Have tried it on both mac and windows (bootcamp on my mac), but got the same message. When im running diagnostic on my usb ports, I get the result that i have 1000mA available for use (with my analog discovery connected) Have tried changing the usb cable but no luck My analog discovery works on other computers Any tips?
  17. Hi, I have a question from a customer. Can anyone help? Would it be possible to do some simultaneous sampling with the analog discovery board with a sample rate of e.g. 500khz or is it time limited due the internal buffer length? Would it be possible for the ADC and DAC at the same time?
  18. I'm an electrochemist wondering if I can use the Analog Discovery to do impedance spectroscopy. I've ordered one to try out, but it hasn't arrived yet so I'm playing around with WaveForms 2015 software. I am no electrical engineer, so I have lots of questions. The normal settings we use in electrochemical impedance spectroscopy (eis) are as follows: Frequency range: 0.01-10,000Hz (1-10,000 probably ok), single sine wave to probe system: amplitude 10mV, use Nyquist (real/imag impedance) and Bode (freq vs impedance/ohm) plots to analyze the system. There are other settings such as wait
  19. Which Breadboards fit to Analog Discovery 2? Do myDigital Protoboard for NI myDAQ & myRIO fit to AnalgDiscoverys connectors? Or to myProto Protoboard for NI myDAQ & myRIO ? Thanks for help! Andi
  20. Hi, I am trying to run the python script "", but cannot seem to load the dwf.dll. When I attempt to run the script in anaconda 2 or Idle (python 2.7.8), I get the following error: runfile('C:/Users/John/.spyder2/py/', wdir='C:/Users/John/.spyder2/py') Traceback (most recent call last): File "<ipython-input-8-4aa4827489b3>", line 1, in <module> runfile('C:/Users/John/.spyder2/py/', wdir='C:/Users/John/.spyder2/py') File "C:\Users\John\Anaconda2\lib\site-packages\spyderlib\widgets\externals
  21. Hi, per my professor's requirement's, I bought The Analog Discovery (link here) which I believe interfaces with the original Waveforms software linked here: . I have a Mac running OS X and am worried these will not work with my system. Any help or guidance is greatly appreciated. Sean
  22. Hi, I have an Analog Discovery and installed Waveforms 2015 on OSX 10.10.5. When I start Waveforms I receive a "No device detected" error. However, if I am running Windows 7 in Parallels on the same machine and launch the Windows version of Waveforms 2015 then the device is detected just fine. I have installed the device driver for OSX. Does anyone have any suggestions? Thanks Bryon
  23. Hi! Is it possible to buy Analog Discovery in Europe (with academic discount)? When I tried to make an order via site it showed it was going to send it from the US. This greatly increases the total price (not to mention troubles with customs).
  24. Hi, I just purchased the adm kit. After installing the software, I've found that when I try to launch it, it appears in the task manager but no windows come up? I've tried reinstalling and restarting everything but nothing seems to help. I am running windows 10 and I downloaded the latest software for waveform. Any help would be great!
  25. I’ve just purchased the Analog Discovery 2 last week and everything works fine when using the Waveforms software. I am now trying to use the SDK to customize my own application by using your sample Python code as a starting point. I was able to run file and everything worked as expected. However, when I ran file, the power supply was not turned on. I used a multi-meter to measure the voltage at V+ and V- pins but they all stayed at zero volt. I also tried to modify the parameters in dwf.FDwfAnalogIOChannelNodeSet(hdwf, 0, 0, 1) function but
