  1. Hello, I tried posting this on the Xilinx forums but got no response. These forums look more active and friendly so hopefully somebody can help me. I am really stuck. I am trying to follow along with the "How To Store Your SDK Project in SPI Flash" tutorial (https://reference.digilentinc.com/learn/programmable-logic/tutorials/htsspisf/start), but I cannot get it to work. I am using an Artix-7 35T Arty FPGA Evaluation Kit. I am running Vivado v2017.2 (64-bit) and SDK v2017.2 on a Windows 10 machine. First, I created a simple "Hello World" program by follo
  2. Hi, I'd like to get information from oscilloscope (like duty cycle, frequency etc.) using SDK in C language. I succeded to pilot the oscilloscope channels and read data with function FDwfAnalogInStatusData(), but I didn't find any method to get info over described. Is there a easy way to obtain duty cycle, frequency etc. info or I have to calculate these info from the data retrieved? Thanks!
  3. Hi all hope you are all doing well. I need to use the SDK and measure all this measurements but apparently there are no functions to calculate for example AC RMS values to call. do i need to come up with my formula or is there any function that can return all the following values ? thank you.
  4. Hi. I have a problem while trying lwIP Echo server wiht Zybo-Z7 I follow this tutorial faithfully https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-getting-started-with-zynq-server/start but I face with a problem This problem occurs for both connection through router and connection directly with my laptop or desktop I try with 3 PC and all of it shows same result. Google suggest me to configure ethernet to be 100Mbps half duplex with Fixed IP settings and it doesn't work. I double-check that I'm using correct MIO pin and fix the 1
  5. Hello I am attempting to follow this but I am confused about section 2.3. It says to place all the application code in DDR. The Basys3 has no external memory but for the SPI flash. From a SPI flash description from an Arty reference, it says but when I read the Xilinx answer record 63605, it says on step 5. Create helloworld application and link to DDR (in the linker script make sure that this application is executing from DDR) Can someone explain to me how to do this all in the SPI flash? Do I need to somehow set that up in my block design in? I do have the QSPI in my blo

    pmod esp32

    Hello, I am working with Artix A7 board, implementing various PMODs successfully. I am having some issue with PMOD-ESP32 unfortunately. The source files from a project off github (ESP32.c/ESP32.h) from https://github.com/mitchellorsucci/PMODESP32 as well as the included libraries (PmodESP32.c/PmodESP32.h) GitHub Project: I believe the following macros need to be re-defined in the ESP32.h file from github, however in XILINX project for Artix A7, there is a uart-lite that is connected via AXI and there is a uart connected to the ESP32 IP. I have tried to define both. When
  7. Hi, I have a question about Waveforms 3 API relevant to the oversampling functionality implemented in Analog Discovery 2. Recently, I am trying to implement the oversampling functionality for my custom-coded software (written in C#) using Waveforms 3 APIs (3.12.2). Based on the reference manual in the SDK, I think that the relevant APIs are “FDwfAnalogInAcquisitionModeSet”, “FDwfAnalogInSamplingDelaySet”, and/or “FDwfAnalogInTriggerPositionSet”. I also found the (seemingly) relevant constants for the first function as follows: “acqmodeOvers = 4” or “acqmodeSingle1 = 5” in “dwf.cs” an

    Pmod wifi SDK problem

    Hi i'm using Vivado 2018.2 + Zedboard, my goal is to use the WiFiScan from the examples attached to Pmod WiFi folder. i have build the project in vivado section and exported it to SDK at that point i'm creating new application project, choose C++ project and select finish. i'm getting the following errors: flexible array member 'DHCPDG_T::options' not at end of 'struct DHCPMEM_T' DHCP.h ‪/proj_bsp/ps7_cortexa9_0/include/DEIPcK/utility‬ line 216 C/C++ Problem flexible array member 'DHCPDG_T::options' not at end of 'struct DHCPMEM_T' DHCP.h ‪/proj_bsp/p
  9. Is it possible to control the power supply and set the voltage of the positive and negative respectively? The aquisition toolbox of matlab (2019a) doesn't allow the possibility of controlling the power supply. The closets solution seems to be to use a h-file library from the SDK (see below). However the header of the h-file (dwf.h) says "This spans all 4 main instruments supported by the WaveForms system: Analog In, Analog Out, Analog I/O, and Digital I/O", the text doesn't leave any information about that the supply can be controlles as well. Further, looking through the functions in t
  10. Hello, I am working through some of the examples for the Arty A7 device. The device seems to come pre-loaded with firmware, some simple reference design that makes use of UART, LED's and pushbuttons. Is there some project I can download to reproduce this reference design? I am planning to overwrite this in the future, but I also wanted to have a copy. Thanks
  11. Hi, I want to read analog data from ad1 pmod. For Vivado part, I use digilent pmod ips to connet fpga. For SDK part, I use AD1.h and AD1.c library in examples. My sensor sends to me analog values between 0-3.3V. (This is a heart rate ECG values). During using arduino, all heart beat data can be read. But I use same function for zedboard, Analog values doesnt look like arduino's. How I can configure and fix this problem? As you see ad1-zedboard connection as below.
  12. hey there I am a beginner to zynq. I have bought a zybo board. I am using vivado version 2015.4. I followed the below link to add zybo board file to vivado: https://reference.digilentinc.com/reference/software/vivado/board-files?redirect=1 then I this tutorial: https://reference.digilentinc.com/learn/programmable-logic/tutorials/zybo-getting-started-with-zynq/start?redirect=1 but it did not work. in this tutorial says: but when I select Hello world demo, I see the below attached image. it says that could you please tell me what I should do? thanks in a
  13. Hello, I am having troubles setting a constant voltage level for a tristate digital out pin on the Digital Discovery using the SDK. I can easily set a constant voltage level for a push-pull configuration using the below code, but this does not work when the OutType is set to tristate. dwf.FDwfDigitalOutTypeSet(hdwf, c_int(1), c_int(0)) dwf.FDwfDigitalOutCounterInitSet(hdwf, c_int(1), c_int(0), c_int(0)) dwf.FDwfDigitalOutCounterSet(hdwf, c_int(1), c_int(0), c_int(0)) Any suggestion on how to implement this for the tristate case?
  14. Hello, I have recently purchased Zedboard along with Pmods AD1 and DA4. I want to implement Gradient Descent algorithm in the Zedboard using these Pmods with bandwidth more than 100 kHz. To get started, I tried to regenerate a analog signal using the Pmods AD1 and DA4. The experiment is completely explained with block design and output plots in the ADC_DAC_1_compressed.pdf. The SDK C code for acquistion and generation (adc_dac.c) as well as for finding max. working speed of DAC (dac_maxv.c) are atttached. The ADC clk is set to 20 MHz and DAC clk is to 50 MHz. It could be observed fro
  15. Hello I'm using PYNQ-Z1 board. I am trying to receive CAN traffic with PmodCAN on the board. Here is my Block Design. Then, Generate Bitstream was successful. (But some warnings appeared and the messages are like Generate_Bitstream_messagex.png) I did Export Hardwear and Launch SDK. When I created the Hello world project in SDK and compiled it, there was no problem. However, as soon as I executed Program FPGA, the following error message appeared. How can I fix this error? ---------------------------------------------------------
  16. Hi, I want to use Nexys4 ddr board to read sdcard, reference this topic and read @jpeyron answer, but after I create the block design with Pmod_SDcard ip and generate bitstream and launch Vivado18.2 SDK tool, an error for new Application Project occur, it may relate to this PmodSD IP, but I an new for using SDK tools. Can you help me how to deal with this error? Thank you! design_1_wrapper.hdf
  17. Dear All, "I'm working with Vivado 2018.3 and a Zybo Z7020 board" I write here because I have a very strange problem in a project that I have been developing in the past months. Namely, I've been writing a verilog code to run on a Z7020 board. This code takes user input as parameters (that are hence hard-coded) and everything works fine with this project (no errors or not understandable warnings...) Now, my job is to make sure that these so-colled parameters can be changed through a serial connection from a laptop. Hence, I've packaged my module in an IP and connected it to
  18. Hello, I have been successful in running the lwIP echo server on the Zybo Z7 board. However, I want to develop a web server on Zynq. I have gone through the lwIP documentation. However, in the discussion of this topic, I was successful in reading the .bin file from the SD card. Now I want to set up a web server on Zynq so I can command the server to read the .bin file from SD card and store it in the DDR. How do I start working on the web server. I have been searching a lot for the tutorial or anything that could make me understand in a simpler way but I failed to find any.!
  19. Hello Digilent Forums, I have an Analog Discovery 2 + Impedance Analyzer board, and have been programmatically manipulating the board via the DWF library. I am now trying to plot Input Phase (∠) programmatically. The SDK for Python comes with a `dwfconstants.py`, which houses values of `c_int()`, corresponding with various measurement types. For example, `DwfAnalogImpedanceImpedance` measurement type corresponds to `c_int(0)`. I do not see a constant for Input Phase inside `dwfconstants.py`. Is it possible to get Input Phase? Thank you in advance for your help!
  20. Hi, I'm trying to use the UART of my Analog Discovery 2 in python. I've had a look at the example and just ran it. At first, I thought it worked. But then I realized it was okay only for the first frame. After increasing the sleeping before the print (see the pics just under), the values are more often correct, but there's still a lot of unexpected results. (see the pics just under ). The thing is, when I use Waveforms, it works(see the pic just under). Also I thought of a problem with the SDK, even if I don't really think so. Could someone help me?

    OpenCV and Pcam5-c

    Hi everyone, I am working in teh demo that was created by Digilent to get images from teh Pcam5-c that is connected by a MIPI CSI-2 interface to teh zybo z7-020 board. In this case, I was wondering if I decide to do the processing of the image (edge detection, enhancement of light,...) I would need to use SDx. I have seen that there are plenty of solutions in OpenCv but I dont know how the hardware proyect and the SDx project can be linked. Note, in this initial design I have teh initiallization od teh camara and platform in a C++ application file that I dont know how if I should export t
  22. Hello, I am a college student currently working on the HDMI Input demo for the Zybo board on Vivado 2018.3 and SDK. I am following the steps provided on this forum, but I end up with trouble displaying the HDMI source onto the monitor. Without any modification, I can get the HDMI source to display properly; however, there seems to be many errors and warnings. In addition, modifying the C code by commenting out some of the switch statements resulted in no change whatsoever. After creating a new bsp and application project, followed by copy and pasting all of the source file

  24. Hello, I am using Vivado 2018.2 i downloaded "Zybo-Z7-20-Pcam-5C-2018.2-*.zip" demo project in original project "part" option is choosen then I created a new vivado project i choose "board" option and i created same block design with "Zybo-Z7-20-Pcam-5C-2018.2-*.zip" demo project. I inserted same IP blocks and made connections. I did synthesis and implementation succesfully but when i exported to SDK and i tried to boot from SD card (i used hello world template) i did not see anything on terminal but when i am trying to export original project to SDK not which i create, then i can see he
