  1. Is there a CAD model available for the Pmod shield? I'm using it with the Arty board (for which I do have the CAD model), and would like to incorporate both into an assembly so I can create a case. thanks! https://reference.digilentinc.com/reference/add-ons/pmod-shield/start
  2. Hi all! I'm currently thinking of purchasing the pynq-z1 board and hoping to set up CAN communication on it. I've read the documents regarding the PYNQ board (http://pynq.readthedocs.io) but I wasn't able to conclude on whether I would need to purchase a PMOD with it to access a CAN peripheral. From what I understood, many of the peripherals are available through the PL via PMODs or an arduino. There was also a comment stating that peripherals such as Ethernet, USB and UART, are connected externally, while all other peripherals are connected internally or routed to PL pins. This confused
  3. Hi what sort of connector cable can be used to connect afe5809 adc board to arty fpga board.
  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/mas

  6. Hi I'm trying to transmit digital signals through a cable. In orther to avoid noise, I am using a differential output (LVDS) to transmit the information from the FPGA to a Cable. At the end of the cable, I'm using a converter to convert the differential signal to a single-end signal (LVDS to Single End converter). For that I need to feed my converter circuit through pin 6 of pmod connector (pin6 = vcc pin = 3.3V). Initially everything was working properly. However the other day, I switched on the board again (Atlys Board) and checked that I no longer have vcc on pin 6 (pin6 = vcc pin = 0V)
  7. Hi, I need help about Pmod I/O. I have a Zedboard and I use GPIO to control some pmod pins to output voltage signal. I use SDK and c language to achieve it, but it seems like that the each time I use "XGpio_DiscreteWrite" it cost me more than 0.1 microsecond, i.e., it changes voltage with frequency much less than 10MHz. This is really slow comparing to its clock frequency. I have noticed that in the embed topic there are arguments about PS, PL side but I have totally no idea about how to improve the performance. On the other hand, I also need to use another pmod pin to "trigger" my board
  8. Hello, I am trying to avoid all of those SPI commands with higher level abstractions. The low-level example seems to help, but it is incomplete. It doesn't show how to setup or toggle the slave select lines. I presume this is done automatically, but I want manual control. I cannot find information on MicroBlaze registers. For example, let's look at XSpi_SetSlaveSelect. This is all I could find: file:///C:/Xilinx/SDK/2016.2/data/embeddedsw/XilinxProcessorIPLib/drivers/spi_v4_2/doc/html/api/group__spi__v4__1.html#ga162523a3e9b29f063701db303ac8cf17 . It's not very clear, or correct. Let me e
  9. Hi everyone I work for car seating company in the UK and we are having an issue with our operators not fitting a specific set of screws. There for I took on the project of making an inductive pen which the operators would need to use in their process to check if the screws are present. However this presented another issue that the operators would then proceed to use the inductive not on the screws but on another piece of metal which they would just tap 4 times to cheat the test. This has led me to find out if it would be possible to develop a positioning system that detects
  10. Hi, I have been working on a PMOD TFT LCD that can be used to play video directly from the FPGA using only two PMODs. I designed the hardware a couple of years ago but recently I had to do a project where I needed to use the Vivado block diagram interface. I thought it was pretty cool how fast it was to put a design together so I went about making an IP Core that controlled the PMOD. It has an AXI Lite interface used to initialize the LCD and then a AXI Stream interface that can be connected directly to a VDMA core. I ended up making three different demos including the followi
  11. Hi, I'm going to buy Pmod USBUART: USB to UART Interface for MicroZed board I have. Would I need a UART Crossover Cable for it? Also, is there any example I could use to have this PMOD working? Any help is greatly appreciated! Thanks a lot!
  12. Greetings! I am using an Arty board (xc7a35ticsg324-1L), and I want to receive an external clock signal which comes from a signal generator. To receive this signal, the Arty board needs a SMA connector, and I recall the Pmod AD5 has two of them: http://store.digilentinc.com/pmod-ad5-4-channel-4-8-khz-24-bit-a-d-converter/ Could the Pmod AD5 be a good choice for my purpose? What would you recommend me? Thanks Fields
  13. 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 (
  14. I'm trying to the Pmod RS485 as a RS-422 interface. In your datasheet, you reference 4 ports. A-input and B-input, which I assume is the Rx; and Y-output and Z-output, which I assume is the Tx. Do you specify which terminal is positive and which one is negative or does it not matter? I appreciate any support you can provide. Thanks.
  15. Hi, I have loaded a Linaro Ubuntu on the Zedboard using Vivado 2016.2 and I want to extract the CoreSight trace data off the board. By applying the same idea suggested in the link http://blog.idv-tech.com/2014/03/22/howto-export-zynq-peripheralsi2c-spi-uart-and-etc-to-pmod-connectors-of-zedboard-using-vivado-2013-4/ , I enabled CoreSight component in the block customization of the Zynq PS, mapped its IO to EMIO, made the TRACE_0 external, and changed my .XDC file to map the 8-bit output data to the JA1 PMOD data pins. However, I'm not sure with my next step. When I powered on my board and
  16. Hello dear We are students whom are working on an IoT project. We want to use the Pmod Hygro to get the temperature and humidity. We also use the Artik530 by Samsung platform, with the Arm processor which supports the I2C protocol. When we try to use the example code given by the resource center of this sensor, we get the error which can be seen in the added file . in addition, we also get a temperature and humidity reading ,but the values are not making sense nor changing as the temperature and humidity are changing. Can you please help us finding what's the problem?
  17. Hello to everyone, I want to show the temperature data with Teraterm . I get from PMOD TMP3 . But I have to design the PMOD TMP3 IP and I do not know what is the difference with led_ip_design on the link there. https://forums.xilinx.com/xlnx/attachments/xlnx/gendis/16930/1/adding ip.pdf Can you help me? How can I show the temperature data?
  18. Hi, I have pmod gps receiver, and I connected it to my zybo board using pmod. I would like to get data from it but it can't connect to the satelite. I have petalinux on arm processor so I execute cat < /dev/ttyPS1 and I receive the gps module output but fields like position etc. are empty. The green led is still blinking. I am waiting about 30minutes and I still have the same problem. What have I do to run it correctly
  19. I made a order with a FPGA board and some pmods and the shipping was about 20 bucks, later down the road if i decided to buy more Pmods for my board, will I still be charged 20 for shipping even if i order only 10 bucks worth of Pmods? I did a checkout without confirming and it still wanted to charge me 20+ bucks for shipping. if that's correct i'd have to save up a lot more and buy a big bundle of Pmods to justify the cost of shipping seeing that it's the same for 1 Pmod or 10 Pmods. correct me if im wrong.
  20. PS/2 interface makes random data from the keyboard when using dev board power, does nothing when using external 5V, tried different keyboards, tried different connectors. Please advise.
  21. I'm using DA4 and OD1 PMod boards in a project. We will have quite a few add-on boards in the device, and I want to get placement nailed down. Is it possible to get a 3D CAD model (.step, .iges, etc.) for them? Many Thanks, -Sberry
  22. Hi everyone; I want to build a real-time control system using the Zedboard. I want to connect the board using the Pmod modules to the actuator and the sensor, and I want to ask you if it is a good idea to do it throught the Simulink HDL Coder. So, My first question is: is it possible to interface the Pmod AD/DA with the board using simulink coder? And how? I did it in Vivado in VHDL but now I want to build the overall system in Simulink and I don't have idea how to do it. Thank you so much. Paolo
  23. Hello All, I tried the program given in http://hamsterworks.co.nz/mediawiki/index.php/Pmodi2s but there is no output on the SD. I have simulated the clock with 100MHz and got these values. clk 10ns 100Mhz Sclk 1.56Mhz mclk 40ns 25Mhz SD is always zero in-spite of setting the input data_l and data_r as Ones as shown in picture and simulation output files. I am unable to find the cause for the problem. Am i missing anything in testbench code, as I am simulating only CLK ? What changes are to be made in that code if i have to use internal SCLK. I have a
  24. Hello I am new to FPGAs, and I'm using Pmods AD1 and DA2 in a control application on ZedBoard, using VIVADO and SDK. Is there any tutorial or hint to know how to start the design and interfacing between ZedBoard and these pmods. Thanks. Elie.
  25. I am using a Nexys dev board (Yes, I know they are old) but I am wondering if I can interface with 5V signals? I see that I can supply the USB 5V out on the PMOD Vcc, so does that mean that I can drive the PMOD with 5V logic?
