  1. Hi @anshumantech, I looks like you posted this on the Xilinx forum (though I don't know why it is marked as solved, so you may want to post on that thread again). Unfortunately, Digilent does not have much in the way of advice as it is my understanding that the Spartan-3AN support is all done by Xilinx and the hardware portion was done by Digilent. Since you have the same OS setup between both boards, I am not certain what the issue might be. Thanks, JColvin
  2. Hi @kranthibabu, What version of Vivado are you using? Additionally, the word document you attached shows you are using ISE's iMPACT, not Vivado. Are you specifically using the Zedboard? Could you also provide a picture of your physical setup with the Xilinx Platform USB Cable and the FPGA? Feel free to attach the details directly in the thread. Thanks, JColvin
  3. Hi @Meins321, The Analog Discovery 2 digital inputs are based on 3.3V CMOS logic with 5V tolerant inputs; there is some more details available in the Digital I/O section in the reference manual here: https://reference.digilentinc.com/reference/instrumentation/analog-discovery-2/reference-manual, so you would need to get the 24V signals to much lower values. That being said, I do not see a way to do this with a single pin. It may be possible to set this up with two possible pins, though I'm not seeing an easy way to do this. @attila, for when you get back from vacation, is setting up an inverting output something that can be done? Thanks, JColvin
  4. Hi @Victor, Yu can ignore these warnings; I ran the 2016.4 HDMI project (generated the bitstream and launched SDK) on the Zybo Z7-10 and can successfully see my desktop extension. Please let me know if you have any questions about this. Thanks, JColvin
  5. Hi @ChrisFishbowl, The part is a linear regulator. Specifically it is ADP123AUJZ-R7 in a 5 lead TSOT package. Thanks, JColvin
  6. Hi @P. Fiery, I have tagged the engineer, @attila, who will be best able to address your question as they are much more familiar with the WaveForms software. Thanks, JColvin
  7. Hi @ChrisFishbowl, I apologize for the delay. Unfortunately, it sounds like that particular IC got burned out. As you noticed, all of these components are surface mount and tightly packed together, so a repair would be difficult to perform (in addition to not knowing if other components are damaged besides the one getting hot), but let me know if you want to pursue that route. Thanks, JColvin
  8. Hi @petera, As an additional thing I forgot to ask, do you have the Digilent board files installed? If not, you can make sure they are installed by following this tutorial that we have. Thanks, JColvin
  9. The pdf version of the reference manual has been updated to include the Oscillator section that was previously missing.
  10. Hi @alexpeck, I have tagged the engineer, @attila, who will be best suited to address your question. Thanks, JColvin
  11. Hi @Geoff, I'm personally not super familiar with getting WaveForms up and running on a Ubuntu system, but if you happen to be getting a crash or segmentation fault when you connect the Analog Discovery 2, I would recommend taking a look at this thread. Otherwise, I will likely defer to @attila for any additional troubleshooting advice. Thanks, JColvin
  12. Hi @mmdsaifudn, Unfortunately, the Digilent staff here on the forum haven't used that FPGA or eval board so we don't have any specific advice for them. I did find a couple of threads that might be helpful here and here. Thanks, JColvin
  13. Hi @MANOJ, I presume you are using an external serializer, but I would recommend taking a look taking a look at the demos we have for the Arty A7 in it's Resource Center, in particular the XADC and the GPIO demo as those take external inputs and then send data to the host computer over UART. Let me know if you have any questions. Thanks, JColvin
  14. Hi @Lucky, I sent you a PM with the contact information. Out of curiosity, what details about the voltage supply, oscillator, and UART details are you looking for that are not explained in section 1, section 5, and section 6 of the Cmod A7 reference manual? Thanks, JColvin
  15. Hi @jfranz-argo, @kharoonian, and @Franky32, I apologize for the delay. I have sent each of you a PM about this. Thanks, JColvin P.S. to other readers, be sure not have Digilent boards attached when you are reprogramming other FTDI devices. A long list of users will tell you it's an easy mistake to accidentally select the wrong device.
  16. Hi @juavo, I asked one of the engineers more familiar with the OpenLogger firmware and they think it would be possible to disable the WiFi via that pin/resistor and use the OpenLogger exclusively over USB. I do also want to clarify (much like other hardware) that making direct modifications to the hardware such as changing/removing the resistor will void the warranty for the board. Let me know if you have any questions about this. Thanks, JColvin
  17. Hi @petera, It looks like the 2016.4 variant of the GPIO project on the release tab doesn't have all of the needed resources packaged into it; I'll request that gets updated. In the meantime, you can use the 2018.2 release variant available here: https://github.com/Digilent/Nexys-Video-GPIO/releases. For this particular release of the project, you won't need to go through the steps you listed in your initial post. You will be able to simply open the Vivado project and tell the pop-up that appears to automatically upgrade the project. You will then be asked to upgrade to some IPs via the Report IP Status. Make sure they are all selected and press the Upgrade Selected button at bottom of the screen. You might see a pop-up that asks if you want to enable core container; go ahead and choose to continue with the core container disabled. You should then be able to successfully generate a bitstream for 2019.1 Let me know if you have any questions. Thanks, JColvin
  18. Hi @Lucky, In general, we do not provide this information. If you wish, I can provide you with contact information of the Digilent employee who addresses these inquiries, though I personally have never seen this request granted. Thank you, JColvin
  19. Hi @czepek88, Thanks for sharing the solution you found! Thanks, JColvin
  20. Hi @Arvid, I have sent you a PM about this. Thanks, JColvin
  21. Hi @Zainab, I believe that is correct that the 1 million samples is only available on the record mode. However, because it is streaming the data over USB, you will be limited to a 1 MHz sample rate and would not be able to use the 100 MHz sample rate you show in your screen capture. The sample rate and frequency are effectively the same thing; the hardware is always sampling at the 100 MHz rate, but the software will report a smaller number of samples. The Analog Discovery 2 (and the original) both have a maximum sample rate of 100 MHz as limited by the hardware, so you would not be able to achieve a 500 MHz sample rate. Let me know if you have any questions. Thanks, JColvin
  22. Hi @Geoff, I believe the issue with the Raspberry Pi's was the underlying USB firmware on the Raspberry Pi end of things. I presume none of these ports have been through a USB hub? Thanks, JColvin
  23. Hi @cepwin, I was actually referring to Xilinx SDK; it usually comes with the Vivado download unless you specifically exclude it. I don't think you would need Adept SDK in your situation. Thanks, JColvin
  24. Hi @petera, Which project are you attempting to run and which version of Vivado are you using? Thanks, JColvin
  25. Hi @cepwin, This particular demo does utilize some IPs created by Digilent that we would need to upgrade to specific Vivado versions. I believe there is a plan to upgrade all of the Digilent projects in the upcoming months, though I do not know to what version they will be upgraded to. I don't think you need to use HLS specifically, though I would probably recommend using SDK (I didn't create the Pcam project so I don't fully know the intricacies). Thanks, JColvin
