  1. I'm on the hunt for a logic analyzer to debug digital protocols. I plan to use it to debug high speed SPI busses (up to 50-80MHz) and USB 2.0 FS (I want to write my own USB stack for a STM32 as a learning experience). My eye is particularly drawn to the Digital Discovery, as for the price it has very high sample rate. I still have to buy a LA though, as I'm still scouting around what works best for me. Therefore, I installed the Waveforms software as a demo, but did not find the USB protocol in there. Obviously it would be complex to write a custom decoder while simultaneously also writin
  2. During device opening internal chips are enabled and configured. This results in consumption increases, specially when the 100 MHz clock (PLL) is started. The needed current increases from 100mA to 500mA. In case the USB can't provide enough current the voltage drops below the minimal required for the device to operate and communication fails. In case you get “Device configuration failed (PLL 1)" or "Communication with the device failed.” error message: The device needs at least 2W/400mA from USB cable. To satisfy this: - Try to use different USB cable and com
  3. If I configure the SPI with mode 0 (polarity=0 and phase=0) and LSB in WaveForms SDK in the Digital Discovery or Analog Discovery 2, and I send the byte 163=0xA3=b10100011; I would see the following: Is it guaranteed that when there is a falling edge of SCLK, the MOSI takes the value just before the transition (the SCLK edge)? What I mean is; is the following image accurate:
  4. I have a device that has a single 16-bits SPI shift register (for both transmissions and receptions). It responds to falling edges of SCLK. The input of the shift register is connected to MOSI and the output to MISO, as the following figure. As the MOSI signal is input to the first flip-flop of the shift register, it should remain stable (not change) during a falling edge of SCLK, while MISO changes its value during a falling edge of SCLK. This way, MISO and MOSI signals are not synchronized. I want to communicate with this device using WaveForms SDK. Is there a w
  5. Are there any differences between Python and C++ version of WaveForms SDK API functions with respect to execution time of the functions?
  6. Hello, I have a first generation Analog Discovery, S/N 210244626692. It recently stopped communicating with my computer. I have tried different USB ports, different cables, and tried a classmate's AD on my computer. The classmate's AD was recognized by Waveforms, but mine was not. Nothing shows up in the Device Manager when my AD is plugged in. -Nat
  7. I am finding that if I set the sweep time to anything over about 20ms, the sweep winds up corrupted. Have updated to current (3.12.2, 64-bit) - no change. Please advise.
  8. Analogue Discovery 2 https://forum.digilentinc.com/applications/core/interface/file/attachment.php?id=12669 https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019Ls1SAE&l=en-US Hi Firstly I would like to say what great product the Analogue Discovery 2 is, I have used it for 8 months to develop a product. It is by far the best PC scope that , I have used. Far better than a PICOSCOPE from the UK company PICOSCOPE or any of the Chinese PC scope knock offs. Analogue Discovery 2 is a serious peice of professional kit and not a toy. This a summary of all
  9. Hi, First, The Analog Discovery 2 is a very handy device and i am very pleased with all the functionality it offers. I got a problem with my device. The channel one of the wave form generator is not working any more. Here is the full the story. i mixed up the scopes for the signal generator and the oscilloscope and i ended up trying to measure a voltage of about 80v with the scope connected to waveform generator. As a result the device disconnected from my laptop. I noticed my mistake, unplugged the scope and tried to reconnect the device. It does show up in the list of available dev
  10. Hi, I was using the wavegen to generate 2 sine waves and noted one weird behavior. - when I changed the amplitude of one channel the other channel also is affected (amplitude and phase) Before change (2V on each channel) After change (3V on each channel) The same behavior occurred on the last stable version and beta version (3.11.4). Thanks
  11. I want to create a little circuit to connect straight to the analog discovery 2 using an analog multiplexer and some of the digital outputs to enable lower sample rate measurement of multiple channels. Would there be a part number for a suitable mating connector for the inputs and outputs of the analog discovery/analog discovery 2?
  12. HI , iam using Analog Discover 2 NI edition, for the first time, i used and measured the RC circuit analysis with Waveform 2015 ,i connected with USB and also external supply also i connected , when i opened digilent waveforms its directly connected and status is OK, then i measured , but all of sudden after its not at all detecting the device, when am selecting the current device in configuration settings its saying the error :DptilO failed ERC:0x2, the device is using by another application .device programming failed .i had used for other PC also saying the same, my Lappy USB serial d
  13. Hi, since forum search did not yield much on subject and there seem to be no built in functions did write little something and decided to share below: Script is quite automatic. It will account for sampling rate, memory depth, oversampling changes in real time - just run it to auto create and configure Ref* channels that will display functions. Possible need fiddle Range a little for integration. If wish reset to auto values just disable/delete Ref* and it will instantly re-enable in default configuration. Attached script is provided in demo mode, does integral(derivative(x)) functional che
  14. 64 Bit LabView 2017 DLLs are not available anywhere. 32 bit DLLs all generate errors. Is there a solution for this? Best Regards... Kamran
  15. Hello, I ordered a brand new Analog Discovery bundle directly from Digilent a few weeks ago for use in a college class, but every time I have attempted to build a simple circuit and connect the board to WaveForms, I consistently get one of the two attached errors. The components of the parts kit have been working fine but it seems like there is a problem with the amount of power being supplied to the Analog Discovery board itself. Any help would be greatly appreciated. Thanks, bucklc2
  16. Dear Digilent Support, I have erased an EEPROM of FT232H of Analog Discovery (not Analog Discovery 2) due to my mistake. Launching WaveFormus "No supported device detected." is displayed. Could you tell me the setting of FT_Prog? Related discussion https://forum.digilentinc.com/topic/2467-analog-discovery-2-ftdi-chip-erased/ Thank you in advance. Best regards,
  17. I have been following many Analog Discovery users trying to use it in Raspbery Pi and also about the problems. I've got a little tutorial on how to use Analog Discovery with Orange Pi PC Plus, an excellent alternative to power the system. https://www.hackster.io/agaelema/using-digilent-analog-discovery-in-orange-pi-pc-plus-b7e865
  18. When I use the waveform generator on my analog discovery 2, the input signal produced has started clipping at around -1.2 or so. I tried it on multiple computers and tried each type and setting and cannot produce correct results. When the amplitude is set to 1V the negative swing does not reach all the way to -1 but the positive swing is correct. When amplitude is greater than 1V it clips on the negative swing. Anyone know what could be wrong?
  19. Hello there!! I'm trying to do capacitance measurements over the time with a Analog Discovery 2 NI edition and save then, as the code on the image below. But now, I need to implement 2 things in this script, wich I would like to know if it is possible to. 1) Save the measurements acquired automatically in a file on the computer (like a .txt or anything like that) 2) Make the script change the frequency of the Impedance meter as it run ( for example, acquisition 0 to 4 runs in 10kHz and 5 to 9 runs in 5kHz) If it is possible, how could I implement that on my script ? Than
  20. Hello, I've got a question on how to sniff SPI data using Analog Discovery with the WaveForms SDK. The following example uses "sync record" which only stores samples on SPI clock or select (rising) edge. This lets you capture SPI data with an average bit rate of around 2MHz. SPI bursts of up to 40MHz are supported but the average rate needs to be lower. DigitalIn_Spi_Spy.py
  21. Hello, What I would like to do is generate N number of arbitrary signals (regardless of Run time). So I configure digital channel as Custom, I then select Samples to be "N" from which a CSV file contains the N logic signals. I also select the Idle signal as appropriate. Now With Waveform 2015, pattern generator has Wait, Run, Repeat configurations. None of these configuration combinations results in just N logic signals and idle for the remaining duration. They always repeat the generation. For example, if I select Wait: None, Run: 20ms, Repeat:1 , there is no repetition which is w
  22. Is there anyone that has a direct link to download just the USB drivers for the Analog Discovery II (not part of Waveforms 2015)? We are having driver issues on Windows 10. We've tried every other solution that we could find on these forums. (Manually pointing to the drivers, rebooting, reinstalling waveforms including the Adept Runtime, etc.) We are looking for JUST the drivers that someone from tech support can send us while trying to fix this problem.
  23. Hi, I am working on a project and I want to incorporate the Discovery for Data Collection. I was wondering is there a way to automate the collection of data using analog discovery so I don't have to launch Waveforms each time to collect data? My project will only include the Analog Discovery as another puzzle piece, there are other boards and chips that will be connected to the discovery for data collection. Once I collect data I would want to pass it on for processing and interpretation. I am hoping to use Python to control the whole system if possible and make most of the processes
  24. Using the analog discovery with waveforms 3, it seems like the UART interpreter is telling me things that are incorrect. I could be completely wrong, and maybe I don't know enough about UART framing to tell, but if that's the case let me know, The data stream I am sending is arranged like so: [FF pad byte] - [data(lower 6 + 2 tag bits)] - [FF pad byte] - [data(upper 6 + 2 tag bits)] - [FF pad byte] - [checksum] To get a much better look at the bits, go to: http://s306.photobucket.com/user/Krb686/media/waveforms_uart_bug.png.html?o=0. Then hover over the image at my photobucket, and click t
  25. Hi re Analog Discovery 2 Configuration in Device Manager is kept default: Scope 2x8k Wavegen 2x4 k Logic 16 x 4k Patterns 16x1k Question: Can Wavegen and Patterns be triggered simultaneously and generate output in parallell, 2 analoge channels and 16 bit logic simultaneous and perfectly syncronized ?
