    Hi

    Dear vwone, We're happy to hear you got a hold of LabVIEW and a WF32. All of our boards are on our reference page. Here you can look at the reference manual, the schematic, tutorials, and even sample projects. The link to the WF32 page is here. If you're looking for more info about labview you can go check out the LabVIEW MakerHub. This is a community just like our forums here but it focuses on LabVIEW. They will have more info about LabVIEW and can help you get started with programming your board. I hope this helps! Welcome to the Community Best Regards, Bobby
  2. Dear ab, Could it be possible to see the circuit that you wired up? it would give us a better view and may help us understand what could be wrong. I did go through and make a quick circuit and I was also getting about 4.8 V. I will read through some of the reference manual to see if there is a reason for this. if you could post a picture of your set up that would be fantastic. Thanks, Bobby

    Map problem on Nexys4DDR

    Dear Anding, I have escalated your question to our APS team who will be able to answer your question. They will answer your question as soon as they can. Best Regards Bobby
  4. Dear Anding, That is a very strange case for pin changing so I went and checked the schematics. I found the two that in the two schematics for the Nexys4 and the Nexys4 DDR that the pins D10 and C11 have been flipped when connecting to the RXD1/Mode1 and RXD0/MODE0. The reason behind this is unclear to me but i'm glad you asked so that way in the future we can know that this isn't a typo. Thanks so much for pointing it out. I would have just assumed it was a typo. Best Regards, Bobby

    PMOD connector spacing

    Dear JasonT The spacing between the PMOD headers is about 0.3 inches. I hope that helps. Best Regard, Bobby
  6. Dear adecold, I looked into that DC motor and it turns out the product title on the webpage is wrong. The 1:19 DC motor voltage is 12 V and the datasheet on that web page is correct also. Sorry about that confusion I'll be sure to get it fixed. Best Regards, Bobby
  7. Dear Christopher, In this video the instructor just skipped some steps to get to an answer faster. The instructor used a voltage divider equation to get the 1/3 and 2/3 values that he used. I have provided a solution of how he found the 1/3 value of his first superposition step. I just used a simple circuit analysis to solve for this to prove that the value of 1/3 of the source voltage makes sense. If you look below you can see my calculations for the first part. I will leave the second part of the superposition problem for you to solve. I hope this helped. If you have any more questions feel free to ask. Best Regards, Bobby
  8. Dear Vardhan, A metal casing would actually help reduce any em fields that happen to be enacting on the Analog Discovery. The metal casing would be used as a sort of Faraday cage around the system. The closer a Faraday cage is to the unit it is shielding the more effective it will be. Since this product is mostly a student tool there seemed to be no need to add a higher shielding unit to the device. You could still keep the plastic casing a then put a smaller metal casing on the inside. The only problem with making a metal casing is that it would make the Analog Discovery pricier. We try to make our products as affordable as possible. Best Regards, Bobby
  9. Dear Vardhan, You definitely could measure 300 volts using a homemade voltage divider. I would recommend against doing it until you are sure you know what you are doing. There are a couple things you will have to consider before making the decision to use a voltage divider. Whether your system is running DC or AC will help you determine what components you will need. You'll need to be cautious of what resistors and other components you use. If you use smaller resistors you will be getting a very large power out put which could fry your set up. There are a lot of different ways to measure high voltage. Explore some of the other options out there and then make the decision. It'll be best to do that to learn about the advantages and disadvantages of multiple options before making a decision. I did find a handy little website where someone used an arduino to measure 300 volts. I hope this helps a bit. I would try poking around the Instructables website to see what other people have made to help you with your idea. If you have any more questions we're happy to help. Best Regards, Bobby
  10. Dear Rob, I got the chipKIT Pro MX7 to try and recreate your problem. Unfortunately/fortunately I was not able to recreate your problem. I do have a question as to what Ethernet Demo you are doing? There are multiple multiple demos and then from that I might be able to pinpoint the issue. Also I would go through and do a check on some the little things. Is your sketchbook location in your preferences mapped to the right location? Did you unzip the folders into the libraries folder where the sketchbook location is? I know this seems little and small issues but I have had countless of issues involving the small things. I hope this might have helped a little but if not we could probably help with more information. Get back to us and we'll try our best. Best Regards, Bobby
  11. Welcome Princeton/Richard, I hope you like the ARTY board and I hope yo do some very cool things with it. If you do do something with it and want to show us or other people feel free to talk about it in the Project Vault section of the forums. I would very much like to see the software radio you are talking about. Maybe you can involve the ARTY in a project for a certain musical about muppets, haha I hope you have fun with your new board. Happy birthday. ~Bobby

    hirose fx2

    Dear vport, The VGA port on the nexys 2 is a female connector. You would male connector but as for type I am not sure. Since we do not sell the Hirose FX2 I will not be able to help as much as you would probably like. If you have any questions about the Nexys 2 our team will be able to help you more with that. Best Regards, Bobby
  13. Dear mb7270, I had to do some research about this software. This is a NI academic product so I do not have all the information I would like to have to answer this question. What I have found may be able to answer. Looking at the full version of Multisim software on NIs website I have found that when you purchase that program you will get a product license which you would input into an account on NI. From there you would be able to down the program and then use your account license to be able to use that program. It appears you would be able to upgrade to a new computer and use that license on the new computer. That information is for the the Full-edition of Multisim. While I do not know if that applies to the student edition I do have a recommendation. If you go onto the NI website and go to their forums or contact their sales department they will be able to give you a more complete answer. I hope this helps. Best Regards, Bobby
  14. Hi Ciro, The dimension of the Nexys 4 board goes as follows: The longest side of the board is 12.2 cm while the shorter side is 10.9 cm. The height of the board (from the pegs to the top of the ethernet port) is 2 cm. As for the part number of the external power jack we can not disclose this information. I'm sure you could find a similar jack at a hardware store or even online. I hope this information helps. Best Regards, Bobby
  15. Dear Capnfrost, Programming for Vivado can be frustrating I understand. Let's see if I can help point you in the right direction. We have a couple websites that can help you in your process to learn about the Basys 3. Your best option is going over and looking at our Learn site. Here we have a multitude of projects and guides to help you with just about basic function you can think of. Next would be checking out the project vault in the forums here. People will often post similar projects that can help you learn how you want to accomplish your task. I did find a particularly useful Learn page that has what you're looking for and it will also generate the a file for your Basys 3 towards the bottom of the page. I would recommend trying to accomplish it yourself before you generate the file that way you can try it yourself. I hope this helps. Best Regards, Bobby
  16. He rajashekar, If you're looking for a specific example using the VmodCam on the Nexys 3 we don't have such an example. The best bet you have at this is edit previous examples to fit what your looking for. A lot of the examples are designed for the Atlys board. You can probably edit the constraints to get those examples working on the Nexys 3. I provide links to various places that have different demos. I hope his will help you in your quest. Nexys 3 - https://reference.digilentinc.com/nexys:nexys3:nexys3 Atlys - https://reference.digilentinc.com/atlys:atlys:atlys VmodCam - https://www.digilentinc.com/Products/Detail.cfm?NavPath=2,648,931&Prod=VMOD-CAM Also I found a forum post on the Xilinx forums that might provide some helpful thoughts. You can view it here. I hope this helps. Best Regards, Robert
  17. Dear Illimi_207, All of our JTAG USB cable have an operating voltage of 1.8V-5V except for the JTAG_HS2 which operates on 1.5V-5V. I looked up the operating voltage for the ATmega644A on this website which says they operating voltage is 1.8V-5V. If you would like to look at the difference between our JTAG programming cables you can look at this website we have. I hope this helps. If you have any more questions let us know! Best Regards, Bobby
  18. Hi there, I think we might be able to help you with some of this. We have an excellent reference page that has a lot of information for our different boards and parts. Here is the link to the Zybo page. Also here is a link to the "Getting Started with Zybo" page which will show you how to add the Zybo to the board listing and how to start a demo using Vivado. The reference pages contain a lot of information that should help you find the answers you're looking for. Our forums get a lot of questions about FPGAs such as the Zybo. A good majority of them have been answered also. Poke around the FPGA section to see if anyone else has similar problems and if they do there's a good chance they have been answered. But feel free to ask any and all questions you have. We are happy to try and help you the best we can. Best Regards, Bobby
  19. Dear Rajbex, What you are seeing is the noise of the signal. Waveforms is probably just filtering out all the unnecessary spikes from the signal to make it look more clean. You can turn off the background signal if you would like. All you have to do is go to the channel the signal is coming from and click the options buttons. You'll see a drop down window with multiple options. Find the noise option and then change the value to 0%. I hope this helps and if you have any other questions let us know! Best Regards, Bobby
  20. Dear GertJL, We don't have any demos for the DP32 but one of our other interns here has made an Instructable about getting started with the DP32. It'll be very helpful to get you started with this board. I also searched for the DP32 on the Chipkit forums. You can look through there and see if they have any helpful material. I hope this helps. Best Regards, Bobby
  21. Dear Marton90p, You certainly could get a virtual machine running on your Windows 10. Another thing you could do is see if you could get the beta for the new Waveforms which I'm told will work on windows 10. It may take them a couple days to get back to you but it may be a safer option then loading up a virtual machine on your system. Check out this forum post to get more details about Waveforms 2015. I hope this helps. Best Regards, Bobby
  22. Dear Jack Z, There's a couple places we can look for this. If you go to the Digilent product page of the Max32 and find the schematic link towards the bottom of the page it will take you to the schematic of the Max32. Also you go to the wiki page of the Max32 and find another link to the schematic view. Once in the schematic you should go to the last page and find the J14 section. That section will label all of the pin names that correspond to whats printed on the silkscreen. So Pin 3 on the silk screen is Pin 7 - J14 on the schematic page and it is OC1/RD0 which can be used as PWM output. I'll give you a chance to find Pin 5. If you have any more question feel free to ask. Best Regards, Bobby
  23. You can downloads peripheral libraries from the Microchip website at this location. I hope this is what you're looking for. If not let me know and I'll do some more digging. Best Regards, Bobby
  24. Dear John, The new version of Waveforms (Waveforms3 or Waveforms 2015) will have Mac OS-X support. You can try getting the beta by looking at this forum post. I hope this helps. Best Regards, Bobby
