  1. We are suppose to add a library from here: https://github.com/Digilent/vivado-library/releases and add it to the projects IP repository list to be able to add the block in the IP Integrator. I have checked all the releases and i cant find the Pmod NIC100 anywhere, i think its called PmodNIC, but correct me if am wrong because i haven't seen it anywhere anyway. Until i find this IP, the Pmod is just another paperweight on my desk along with my stalled project, Please help. I am using the Arty A7: Artix-7 FPGA Development Board.

    Pmod wifi

    Hi, I have two problems regarding wifi 1- I am trying to connect the pmod wifi to an arduino uno. I looked for a library, the best I could found is the WiShield https://github.com/airsoftsoldrecn9/WiShield . Clearly, this library is for the WiShield https://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=90_186&products_id=2165 but I thought because they use the same wifi chip as the pmod wifi this could work. However, after I manage to compile the library (I attached the working library after some minor modification in order to for it to compile) and after I connected the pmod wifi to the SPI of the arduino uno nothing seems to work. I tried to debug and I noticed that the code stuck in initialization stage, specifically in the file g2100.cpp line 144 (do-while loop). Could any one be kind enough to help or, if there is a working library for pmod wifi, that would be great. 2- I have the chipkit wi-fire rev C,I tried the example WifiTcpEchoServer which is working just fine. However, I need to make the kit act as TcpClient, so I tried the example WifiTCPEchoClient, however it does not work. The problem is that the kit does connect to the router, however, it does not connect to another tcp server on the PC. I tested to see if that is a problem with firewall, but it is not. I tired to debug and I noticed that the code stops at deIPcK.tcpConnect function. I appreciate any help. Thanks WiShield3.zip

    PmodRS485 on Zybo

    For various reasons I need to use RS485 for communication with my Zybo board. PmodRS485 seems to be a perfect add-on module, however, so far I could find only an MPIDE example. In my understanding Xilinx Uart should be the way to go because the Analog Devices chip is supposed to take care of the protocol. Correct me if I am wrong. Hope someone has such experience and can share it with us. Thank you!
  4. Hello, some people might already know The PoC-Library. It's a collection of over 120 free and open source IP cores, that are platform independent. The IP core work on Altera, Intel, Lattice and Xilinx FPGAs of any device family. The core are describe in platform independent, generic VHDL code. If vendor primitives are required or better implementations can be achieved, a configuration mechanism will select a suitable implementation. PoC has gotten a first simple set of new I/O controllers abstracting Digilent's Pmods. These are located here: https://github.com/VLSI-EDA/PoC/tree/master/src/io/pmod I might wonder if users in this forum or Digilent itself would be interested to add more Pmod abstraction layers for modules like the temperature sensor, OLED displays, ... I'm going to release a set of basic I/O controllers for I²C, OW and SPI soon. These can then be used as a communication base for higher level protocol implementations to the Pmods. If one is interested or has questions, please let me know. You can contact me e.g. via Gitter: https://gitter.im/Paebbels Kind regards Patrick Lehmann
  5. Hello! Recently I bought a PMOD AD5 board to hook it up with my Arduino DUE in order to measure AC Voltage. In terms of libraries, I tried two - the official AD7193 library and the AD Converter one, from GitHub. The AD Converter one seems like it's based on the official DSP library from your wiki, but adapted to Arduino. With that one, I had a few problems, so I went with the other one. For starters, I have my signal connected to AIN3 and GND connected to AIN4 (both on J2). The SPI is properly connected to my DUE, settings are SPI_MODE3 and SPI_CLOCK_DIV32 (initially it was DIV16, but I decided to try 32 as well, unfortunately to no avail). I am powering up everything from the 3.3V pin on the DUE and my signal is 50 Hz sine wave, with a 1.65V reference. I am measuring it with normal differential type, not the pseudo type (even though I tried that). Originally, with the default library, I could measure the 1.65V, but the sine wave isn't there (because of the 50Hz/60Hz rejection filter). Trying out different things with the mode and configuration registers from the AD7193 datasheet, I tried to set it up the following way: Chop Disabled, SYNC4 (and SYNC3 afterwards), FS=1; which from the datasheet it said that the 50Hz and 60Hz rejection would be disabled. I tried a whole lot of things, but I just couldn't get the filter turned off. Reason I am writing this is that I am hoping someone here can help me with my dilema and give me the means of measuring AC Voltage, because the ADC is great. Here are my register values: Mode - 0x080001 Configuration - 0x000208 I got these register values from the AD719X AFM Simulation Software. Running this configuration there, with 5MHz of the SCLK generates the Frequency diagram exactly as I need it. But for some reason, with the Arduino library, that just doesn't want to work. Thank you a lot for reading and I'm hoping someone can help.
  6. Hi, I need a library called <plib.h>. Seems it is a quite commonly used library, but I could not find anything to download on-line. Could someone point me to where I should download it please? Thanks, Jack

    reading program counter in Xilinx SDK

    Hello everyone; I am using Zybo board with standalone OS using Xilinx SDK. I wonder to know if there is any library or board support package that I can get the value of PC (Program Counter). The reason I am looking for that, is that I want to measure how much clock cycle does a portion of my code take (by calculating difference between PCs at two test points of the code). Appreciate your comments.
  8. Hi all, I've recently bought an Arty board (Microblaze processor) and some Pmods (PmodDPOT, PmodDAs, PmodADs), which use SPI protocol. I've looked everywhere for an example on how to access the Pmod headers or just how to use Pmods with the Arty but I couldn't find anything (even on the reference wiki page for the Arty). I found a library for SPI on Xilinx SDK which is called Xspi but I also am not sure how to use it. Can anybody perhaps help me by giving me the basic steps on how to do this? I'm very new to FPGA, so any feedback or suggestions are welcome! Thanks Viv
