  1. Hello everyone. I'm working on a project wtih my friend. To accomplish it, we need to get 12 bit data from microphone and observe the output on LEDs. We couldn't figure out what is wrong with the code...spi_master.vhd mic3_xdc.xdc mic3.vhd spi_master_cs.vhd
  2. I am trying to connect my PMOD MTDS to the Zybo Z7, without Arduino. I have integrated the IP files, connected it via block diagram, and set up a FAT32 microSD with the 2 files that are needed also. When trying to connect to Vivado I can seem to figure out how to get to the console for which I can do MTDS Firmware code so I can do a custom UI. Documentation does not help much with connecting this PMOD. Please advise if you're familiar thanks.
  3. Trying to connect the MTDS PMOD to my CoraZ7-07S FPGA board. I used the Digilent MTDS IP but I'm having trouble figuring out how to connect it to PMOD port JB on the Cora board. Read on another answer that I should use JD by default but that's not an option in Cora. Vivado (2019.1) also warns that the IP was packaged for arty board but assume that's not an issue for me other than the JD issue. I saw on another post that I need to edit the XDC file to change the PMOD connector but I don't see how I can do that since the MTDS PMOD doesn't show on my constrains file. Thinking about wiring it

    Pmod RF2 IP ?

    Hi I purchased the pmod RF2 and i want to know if you have an IP design for it in Pmods library ? Thanks for your reply Soufyane
  5. Hi, I am writing a systemverilog controller for read and write to ft313 chip internal memory. Kindly help me on whether i can use pmod for the external interface which consists of 16 bit bidirectional data, 8bit address bus, chip select, read and write signal. with outputs defined as reg, Do i have to use bram specifically or it is taken care if defined as reg.
  6. Hello, I have a Nexys Video and a Digilent Sevent Segment Display PMOD. I want to drive the Sevent Segment Display using the Nexys Video. The only two matching PMOD headers are JB and JC but they are are marked on the manual (https://reference.digilentinc.com/reference/programmable-logic/nexys-video/reference-manual) as "differential". However, on the Digilent provided XDC constraints file, the pins are individually controllable and marked as LVCMOS33. Can I use those pins as normal single ended PMOD to drive the seven segment display? Thanks!
  7. 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 <
  8. I recently moved my HDMI project from S7 to A7, and I am getting implementation warnings leading to bitstream errors. On the S7, I had to following setup // HDMI notes: we're using pmod JA. // for the S7: // top row is N14, M14, L18, L17 // bot row is N18, M18, M17, M16 // so TMDS1 is {L18, L17} = {hdmi_out_n[1], hdmi_out_p[1]} = green // so TMDS0 is {N14, M14} = {hdmi_out_n[0], hdmi_out_p[0]} = blue // so TMDS2 is {M17, M16} = {hdmi_out_n[2], hdmi_out_p[2]} = red // so CLOCK is {N18, M18} = {hdmi_out_n[3], hdmi_out_p[3]} where my constraints file has ## PMOD Header JA se
  9. I would like to integrate PMOD NIC100 with Microzed board with Zynq 7020 running on linux. I have a SPI interface routed through the PL logic. Are there any IP that can be directly imported to Vivado for this ? OR Are there any drivers that can be installed on the linux ? Please suggest.
  10. Hey All, I am trying to make a simple IP block design in Vivado 2018.3 to test the ESP32 PMOD out using AT commands for data transmission. I will attach a picture of my current block diagram to this post. I am getting a critical error (reference below) that says the IP has a packaged board value of "digilentinc.com:cora-z7-10:part0:1.0" which is for the Zybo z7 board. My questions are: Q1)Will this design work regardless of this error, as the Zybo and Zed boards are similar and both run off the zynq-7 architecture? Q2)If the answer to Q1 is "no", is there a method of adapting t
  11. Hello all, I would like to generate a user-defined clock (1.8V 24MHz) out from the board. (for other devices) After I use a clock_wizard to generate a 24MHz clock and make external, which pin is suitable for assignment? 1) Choose Pmod JA1 (EPP pin = Y11), however, the pin is 3.3V in default. Should I buy a Pmod level-shiftier ? 2) Is there any other proper external IO recommended? Thanks.
  12. Hi everybody, I have an RFID module which can be controlled through an RS232 communication. I have tested it with a rs-232 connection with a PC and with an also with an usb-serial converter. I can connect with the RFID module an receive its data through a terminal emulator such as Teraterm, PuTTY, etc. The data are simply ASCII strings of codes. The module can also be configured by sending some ASCII commands, this is also tested. Now I want to do the same with a microcontroller (Arduino, Lopy, etc.), i.e., the microcontroller would act as the PC, getting data from the RFID reader. I
  13. Hi, I want to connect the pmod oled display to my raspberry pi, but I'm not really getting the hang of how I should wire it. If someone can explain where to plug in each pin and how to code it that would be great. Thank you.
  14. I think my question is general but i want to know how to initialize Pmod OledRGB using case when-statment i found some vhdl codes using this method but i cant understand it
  15. Looking at https://reference.digilentinc.com/reference/pmod/specification?redirect=1 I see what appears to be template text lower in the page. Wondering whether that's intended to be filled out at some point?
  16. I am trying to use a Pmod485 (P/N 410-310) to connect an Arduino (TTL) to a motor controller (RS485). I am only using 1 Pmod485 and I am assuming I do need to short JP1, is this done just by sliding the blue cap over both pin headers? Also, the IC block diagram shows 2 separate GND (GND1 and GND2) but the module only has 1 GND available on the pin header. Does this mean both GND on the IC are connected together? pmod_pmod_pmodrs485_rm.pdf
  17. 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

    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
  19. Hi everyone ! I have little project to do :displaying an image on PMOD Oled in VHDL Language. I took the Nexys4 vhdl project and tried to make it run, i have an Basys 3 Board,so i've just replaced some constraints with mine on the Board,and it gives me Failed Bitream Write:W5,J1,L1 are not valid site or package pin .Why are they not valid pins,Do I need to make extra stuff to make it work on this Different Board ? I'll attach the constraint file below.Thank you in Advance. Nexys4_Master.xdc
  20. Hi, I recently purchased one of the LabVIEW Home Computing Kits with the Beagle Bone Black along with a PmodDA2 (I2C interface) and a PmodDA1 (SPI interface) from Digilent. My goal is to make low cost, LabVIEW based controller for an EV that I have built. I was able to get the BLINK VI to work without any issue once I realized what Debian Image would work with LINX. (As mentioned on this forum 8.6 is the latest). I am currently running 8.4 on my BBB but I cannot seem to get the LINX I2C interface to work. The code required for the PmodDA1 appears straight forward compared to other,
  21. I am working on a project that involves a PIC24E and a PMOD NIC100. Is there any library or examples about how to make them interact with each other? Thank you in advance.

    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
  23. Hello, I've been trying for over a two months to make a project including the PmodWifi for sending data from PIR motion sensors to a computer with wifi. At fisrt I was working with Basys 3 board that I had but I undrstood that it doesn't have enough memory space. So I got Nexys 4 DDR board and tried using it there. Unfourtunatly I had some trouble with configuring the DDR so I reached some professional help from an engineer that works in the field. He gave me a new board, Zynq UltraScale+ MPSoC ZCU106, that he knows for sure how to work with and configure. We managed to generate

    ESP32

    Hello, I am working on integrating ESP32 PMOD into a vivado 2018.2 project. I have imported DIgilent IP library into Vivado. When I place PMOD and connect to board, during compilation. It is actually a general message from the block design (See attached image). It apperas to me that this IP is for ArtyZ7? or some other Zync product? If so, is there IP available for Arty A7 or is this message to be ignored?

    Artix7 & ZedBoard

    Hello, My group has acquired the two boards Artix A7 and ZedBoard for developing some applications. I am noticing couple differences regarding projects and documentation. One such difference has to do with the reference base design. For Artix A7 I am finding the PMOD ports, and I2C, SPI, UART, Ethernet included in Board connections. For ZedBoard, very few peripherals are included in the base design I was able to locate. Question: For developing new applications for Zynq, can you provide some information regarding Zynq base desing. Is there more complete project for i
