  1. Hello I am creating a verilog module on the basys 3 board to interface with the Pmod DA3. I have tried running the module with the DA3 connected and wasn't getting any voltage reading. I have my sclk speed at 25Mhz. Below is my current code and screenshots of my test bench and the pmod outputs on an oscilloscope. Any help is appreciated. `timescale 1ns / 1ps module sclk( input clock, input reset, output sclk ); reg[24:0] count = 0; reg sclk = 0; always @ (posedge clock or posedge reset) begin if (reset ==1'b1)begin count <
  2. I had left my board connected to my laptop and power to the board was abruptly cut off when the laptop died. I tried to connect the board to a different computer and realized that it no longer turned on. Though, the computer's device manager shows that something is plugged in. Yet, adept and vivado are unable to recognize that a device is connected - on vivado I was planning to restore the board to it's default setting using a .bin file but received the following error message: ERROR: [Labtools 27-2269] No devices detected on target localhost:3121/xilinx_tcf/Digilent/210292AA77E6A.

  3. Hello, I'm new to this form, looking for some help with the Dual H bridge PMOD DHB1. I connected my power supplier to J4, my motors to J5 and J6. I have a custom IP that uses switches to drive motor speed with most significant bits of a duty cycle for PWM output at 2kz. I also have 2 switches connected to the DIR1 and DIR2 respectively. I also have button 3 connected to a reset condition to initialize code, inputs and outputs. To help debug, I connected the EN1 and EN2 output of the custom IP to the board LEDs to confirm that the signals are working correctly. I also checked the
  4. Hello! I am working on implementing the IBERT IP core on the Genesys2 dev board. I have purchased this daughter board to connect to the FMC, but I am unsure of how the pins relate to the SMA connectors. Has anyone used this daughter board before? I have emailed Hitech Global for documentation, but I have not received a response as of yet. Also, does anyone know if a guide such as this one exists for the Genesys2 board? I assume that the steps would be very similar since they both use the Kintex-7 FPGA. Thanks
  5. Hi, I am trying to generate a pulse wave instead of a continuous wave which is the default of Waveform Live. Is there a way to do this? I am also having a problem using the math function which is located in the bottom right of the browser, It freezes the site when it is selected.
  6. Since you folks an Digilent make these wonderful board files that make it super easy to connect components, I figured I'd make my own for a custom board. The problem is that my design uses a differential sysclock, whereas most Digilent designs use a single-ended sysclock. I have been pouring over the board file chapter in UG895 to figure out how to do this, but unfortunately I haven't found any examples or hints in doing so. A single-ended clock interface in the board.xml file looks like this: <interface mode="slave" name="sys_clock" type="xilinx.com:signal:clock_rtl:1.0" of_
  7. Good evening, My Openscope at the beginning worked regularly both as a agent and in wifi. One day he stopped working, but after a few attempts he has resumed regularly. Now I am again in the same condition, the device is not responding and when the connect on the USB port is not even seen the com. LED 4 flashes continuously and I also tried to send it to boot mode, the com is not seen the same. What can I do? Best Regards and thanks! Alfredo

    Zybo tutorial help

    i currently have a project where i need to produce a tone from a zybo board and to familiarise myself with the board i downloaded the pdf from http://www.zynqbook.com/download-tuts.html and the zip files but and i do the tutorials step for step but when i try to run the programme on the board nothing happens im using vivado 2017.1 i have the ports set to 115200 baud when i import the c code i get a warning from xparamaters.h i asked my project manager and they said its because im not using costraints but the turtorial specifically mentions not using constraints can anyone tell me w
  9. Hello, I am making a project to make the XADC read voltages, and I want to multiply the voltages from channel 1 and channel 2, do I need to send the two voltages to the multiplier at the same time? And if there is a delay when I get those two voltages, how can I send them at the same time. New to the FPGA, please help me. Thanks in advance.

  11. Hello everyone, For a school project, my group is trying to make a 3D printer and we need to run 4 stepper motors (3 for motion and 1 for the extruder) using myRIO. Since we would need 4 drivers to run each motor, we are thinking of using a combination of these following adaptors. We are also wondering how could we control the heating element in the extruder using the myRIO controller? 2 of the Pmod Adapter for NI myRIO http://store.digilentinc.com/pmod-adapter-for-ni-myrio/ 4 of the Pmod STEP: Stepper Motor Driver (2 connecting to each Pmod Adaptor) http://st
  12. I can't get my brand new AD2 to connect to my Mac. WaveForms2015 reports No device found. I don't know if there's any kind of power LED on the Discovery 2, but if there is it's not illiuminated. I followed the guide here: https://reference.digilentinc.com/learn/instrumentation/tutorials/ad2-waveforms2015-installation-osx/start and rebooted as well. Meter says 1.2A off the USB on the Air. No love. Help!
  13. Hi, I bought an analog discovery few months ago and been really happy with my purchase but for one point: I'm unable to analyze spi protocol with the logic analyzer. I have no problem using the software to see slower protocol such as uart, but when it comes to spi, I can't get the settings right to see the bits in a spi line. I'm joining a picture of the software with the data that I get... I can confirm that actual spi data is transferring in the line that I am probing and that the analog discovery cables are at the right place. Thanks for your help, Mar
  14. I am attempting to sample values from the XADC and use those values to control a video display connected via VGA. Both of these parts work separately, but when I attempt to combine the hardware for the two, the XADC stops working. Specifically, the XADC still returns values, and those values still fluctuate slightly, but they don't represent the voltage anymore. I'm using the XADC in single channel mode, and have tried both channels 6 and 14. I've connected my analog input to PMOD-JA in the appropriate places for channel 6 and 14. Both of these channels function perfectly in my XADC o
  15. Hello all, I am writing C code for the arty board to basically emulate the automotive SENT protocol. I just need to know if the output pins are open drain on this board to prevent accidental loads that could damage my parts. Let me know if any further information is required. Thanks, Tim
  16. Hi every one. I was Created HLS Ip Core. This Core is a simple Image Filer, and the input for this Core is a matrix of picture that I built in Matlab, Now I'm trying to have a input from HDMI and filter output from VGA. In other words, I don't know "How create a simple block design in ZYBO for have HDMI input, VGA output and HLS IP CORE?" and "Which commands need to read frames from input in SDK sowftware?" Best regards. Abish SJ
  17. Hi everyone! I'm Jorge an Electronics Engineer who want to buy the Basys 3 FPGA for the first time. I took some FPGA subjects at the University and I did some practical stuff using a Spartan 3 FPGA and Nexys 2 through ISE design suite. Now I want to have my own FPGA to continue learning myself and do some crazy stuff. Basys 3 description sais that it is not supported by xillinx ISE, so the only possibility is to use it through Vivado. My big doubt is: should I buy the 'Vivado Design Suite Voucher' together with the FPGA?? It is only 10$ difference. What is the difference between buy

  19. Dear Community. I've recently bought a Zybo Zynq board and i'm having some getting started problems. Im known with both C and VHDL programming before but i've never had such a multi-purpose FGPA, dualcore board before. I tried following some basic tutorials, like: https://reference.digilentinc.com/zybo:gsg http://www.zynqbook.com/ and several youtube led blinks. But I'm experiencing different problems with all of them. My board isnt listed in the Vivado 2015 > new project > boards list I can't find the right settings to get the leds to the GPIO Or when I find a "pre made tutorial led bl
  20. Hello all, I am trying to program a Basys3 to perform basic logic functions. It seems like it would be really easy to accomplish but I am still a little unclear how to program the board as well as write for Vivado. For example I think that I should be able to, in theory, program the board to be an AND gate by writing a program that looks at switch 0, switch 1, and LED 0. If switch 0 and switch 1 are both switched on LED 1 comes on. It sounds super easy I just have no idea how to write in vivado. Any help would be super appreciated. Thanks Capnfrost
