  1. Hi @catphish, I took a look at the possible build list for the Arty S7 and it seems that the Piecemaker board is a build option for the two versions of the Arty S7, which I was surprised to learn. The datasheet that I am looking at the for the Piecemaker DDR chip (link to datasheet) seems to say in some places that it will work with either voltage (such as in the description on page 4 and page 11) but the list of the parts list on page 5 seems to say only one particular part works on 1.35V. However, we have one of these Arty S7 boards with that same PMF511816EBR-KADN chip and we verified that it works correctly and measured the capacitors that it runs at 1.35V. I have reached out to our design engineer for this board to confirm this though. Thank you, JColvin
  2. Hi @RedMercury, I learned that those distances do not include the leg distances, so they just go to the through hole. Based on the datasheet for the female Pmod header you should be able to find out those details if you want to though. Thanks, JColvin
  3. Hi @RedMercury, I have reached back out to our layout engineer to find out this detail for you. Thanks, JColvin
  4. Hi @spri, I have moved your question to a more appropriate section of the forum where the engineer much more familiar with WaveForms SDK will be able to see and respond to your question. Thanks, JColvin
  5. @zygot no problem, I'm glad I could help out. For others reference (just in case there are other situations where the pdf displays differently than the two situations mentioned on this thread), this is what I see on page 3 of the schematic in my Firefox browser on my Windows 10 machine: Thanks, JColvin
  6. Hi @zwilcox, We weren't readily able to update the Zybo Base System Design to a newer version of Vivado. We do have an unofficial version of a Zybo Base Linux Design for our Petalinux Projects here as well as a Zybo Petalinux BSP Project for Vivado 2017.4 here. Thanks, JColvin
  7. Hi @zwilcox, Unfortunately, we do not have an updated Zybo Base System Design. We are looking into updating this, though since it was originally created in Vivado 2013.4, I do not know how successful this will be. Thanks, JColvin
  8. Hi @zygot, So I can ensure the correct schematics are available, which current schematic are you referring to that doesn't have these details? The current version that I am aware of (Rev B on it's Resource Center) shows all of these details on the 3rd page. Or am I misinterpreting what you are saying? @eric_holtzclaw, to confirm, yes changing out the clock chip will cause the USB interface to break. There is a location where you can provide an external oscillator on IC4 (intended to be 100 MHz), though you would need to remove R80 so that it and the USB clock aren't interfering. Otherwise you can always using the clocking wizard to create a PLL to create your 32 MHz signal if you don't strictly need an external source. Thanks, JColvin
  9. Hi @tmwhitt, What voltage range are you applying the inputs on the Pmod AD1? Thank you, JColvin
  10. Hello, For those reading this thread, I have sent a PM with instructions on how to reprogram the JTAG SMT2's. Thanks, JColvin
  11. Hi @SeanS, Thanks for sharing what you found to solve the problem you were running into! Thanks, JColvin
  12. Hi @NikosFotias, I heard back from our design engineer about this; the recommend input ranges are 0V to 5V, but the absolute maximum ratings for the PWM inputs are -58V to 58V. Thank you, JColvin
  13. Hi @Musko, You would receive better support for this question by posting on the National Instruments forum, https://forums.ni.com/t5/Discussion-Forums/ct-p/discussion-forums?profile.language=en; the staff here on the Digilent forum are really only familiar with the LINX add-on for LabVIEW and the LabVIEW 2014 Home Edition. I'm sorry I could not be of more help. Thank you, JColvin
  14. Hi @edge30, I have reached out to some of the other engineers more familiar with embedded Linux about your questions. Thank you, JColvin
  15. Hi @mossygreen, My understanding (I don't have a Mac to confirm this) is that you should be able to click on the Apple icon on your screen and then select the Software Update option. Otherwise, I would get the FTDI drivers (what the OpenLogger uses to communicate) directly from the FTDI website here; you might need to uninstall the existing drivers first to help facilitate this. Let me know if you have any questions about this. Thanks, JColvin

    Hi @tomas61, When the experiment is running, you can use the mouse scroll wheel to adjust the settings in the Arbitrary WaveForm Generator, though each setting will jump to the predefined settings that you can see in each of their dropdown arrows. Additionally, you can change form the Simple view to Basic view (image attached) to go the style of the original WaveForms. Let me know if you have any more questions about this. Thank you, JColvin
  17. Hello, Those of us here on the forum here will not be able accurately respond to your question. You will need to contact our sales team (sales at digilentinc dot com) to receive accurate information about the academic discounts. Thank you, JColvin
  18. Hi @amamitof7am, I do not think the Analog Discovery 2 will be visible on NIMAX. None of the Digilent staff have used the Analog Discovery 2 with LabVIEW 2019, as we have not worked on this since late 2016. What I have seen in this thread is that the Digilent WaveForms VI set is compatible with LabVIEW 2017 though the AD2 toolkit was not compatible with it. Beyond following the Instructables that demonstrates running it on LabVIEW 2016, I'm not sure if there is anything else that can be done to get it working correctly. I'm sorry I could not be of more help. Thank you, JColvin
  19. Hi @JamieJ, I don't know the full answer to your question (the engineer much familiar with this will be able to respond when they get back into the office after the weekend), but there is some information about the impedance of the Analog Discovery 2 on this thread here. Thanks, JColvin
  20. Hi @wimtormans, Digilent did make the LINX driver. However, no work has been done on it since late 2016 and there are not any plans to update the LINX 3.0 driver for Raspberry Pi 3.0 deployment for newer versions of LabVIEW, so that particular functionality is only compatible with LabVIEW Home 2014. Thanks, JColvin
  21. Hi @mossygreen, They let me know that they don't know why there are two device listings showing up for the OpenLogger; when they test on the Mac machine that they have only a single set of tty and cu devices. With that in mind, their only guess at this point to help with this would be to try updating the device drivers; they realize this isn't much help but it's their best understanding of the situation at this point. Thanks, JColvin
  22. Hi @mossygreen, It sounds to me like you're doing everything right; I've pinged our firmware guy again to see if they have some additional input. Though apparently I didn't send this message yesterday informing you of this like I thought I did. Thank you for your patience, JColvin
  23. Hi @edge30, I don't think any of us here at Digilent have attempted to use buildroot or other open source tools specifically with the Cora Z7, so the staff here will be of limited help in that regard. Perhaps some other community members have attempted this, though some basic searching online (which it sounds like you did) didn't seem to turn up anything particularly helpful. Thanks, JColvin
  24. Hi @mossygreen, I talked with our firmware engineer more familiar with the OpenLogger and they let me know that they have been unable to recreate the Access-Control-Allow-Origin errors or the broader issue that you are experiencing. Are you using the localhost version of WaveFormsLive (or how are you accessing WaveForms Live)? It looks like you are attempting to do this through Safari, but I'm not certain. Additionally, the original URL you posted has mixes of the OpenScope and the OpenLogger, which is in accurate so the when the you attempt to update the firmware the URL the app figures out is wrong (hence why the process is failing). Could you update the offline build (the zip file for it is here) and then try updating the firmware? There are some details on how to do this here. Additionally, to confirm based on what I am seeing, you are connecting the OpenLogger to your iPad? Or am I misinterpreting that entirely? Thanks, JColvin
  25. Hi @joniengr081, You should be able to attach files now as part of a reply to a thread; you were in a different member account type since you had created an account but had not posted anything within a month or so of creating that account (this is done as an attempt to help prevent any bots from just waiting until their account is "old enough" before attempting to spam). I apologize for the confusion. Thanks, JColvin
