    MRAM PMOD

    Hello, I need to develop software to control an Magnetoresistive RAM (MRAM). I searched for an MRAM PMOD and found this item out of stock. https://www.tindie.com/products/alliedcw/pmod-mram-nonvolatile-memory/ The picture shows a Digilent board but I do not find it on your website. Do you have any of these on hand? Why don't they show on your site? Pete
  2. Hi, everyone here. Now, I have tried with my Pmod AD1. I used the demo code provided by the Digilent, but the value shown in the Vitis Serial Terminal is different from the value I have seen in the multimeter. For example, when I insert my sensor A into the channel A0, the value shown in 2.56. The value shown in the multimeter is 2.9V. When I insert my sensor B into the channel A1, the value shown in the Vitis Serial Terminal is 1.08. The value shown in the multimeter is about 2.1V. When the sensor induced voltage exceeds 1.8V, the AD1 value returns back to 0. I thi
  3. I'm trying to get the Pmod Color module for the Zynq z7-10 to work but it doesn't appear to be on. I was following along the instructions from these sites: https://reference.digilentinc.com/learn/programmable-logic/tutorials/pmod-ips/start https://projects.digilentinc.com/arthur-brown/displaying-color-readings-with-the-pmod-color-and-python-ebd794 and I have it connect to the device as such on the board's JA port: Following along with the first link, I skipped the steps where a clock and interrupt were added as the data sheet shows that the Pmod Color IP does not requi
  4. Greetings, It is my first time here so I apologise for my mistakes, I started a new project where I am using Nexys 3 board with a Pmod GPS module. I found a UART receiver/transmitter on the internet I wanted to test it out. So I connected the receiver to the USB UART Rx pin, in order to send from Serial COM data and then transmit back to the Serial COM the data I have sent. When I am sending a character from the serial, I receive the same character from the UART transmitter so I think that both of the components work fine. When I am sending the character A, I receive back the character A
  5. I am currently doing the vertical farming project. And I want to put my Pmod HYGRO and Pmod AQS sensor into the same port JC. I have tried to put my Pmod HYGRO and Pmod AQS into different Pmod ports successfully. Now, I just want to combine these two sensors into one port. For example, for port JC. I want the top layer of the port connect to Pmod AQS and the bottom layer of the port to the Pmod HYGRO. So what is my first step to do when comes to vivado block design and how am I going to write my Cpp code into Vitis IDE? I did some primary research on this topic before. I may n
  6. I want to use PmodIOXP to allow both PmodAQS and PmodHYGRO to be connected into the same port in Zybo Z720. However, I do not know how to write my block design in Vivado since there is no IP for PmodIOXP in the vivado-library. Also, what kind of C++ code should I write in my Vitis after I exported my vivado file into Vitis
  7. Hello, i just bought a PmodBt2 ( https://reference.digilentinc.com/reference/pmod/pmodbt2/reference-manual?redirect=1 ) the RN42. What i want to do is to use a Zedboard with PmodBT2 to capture all bluetooth packets that are being transmitted nearby and then analyze them using the PL and PS, so far I've managed to make the model in vivado ( thanks to some help from this forum ) but I'm unable to tell is this project is going to work from now on because I can't find a way to configure the module in this manner based on the documentation and reference manuals ( http://ww1.microchip.com/down
  8. I'm trying to run the PMOD BT2 core on a Zedboard, using vivado 2020.2 ( i have not tried other version to be honest ), later i'd like to use this hardware to work with petalinux and write a driver for the bluetooth module. I've been trying for a week now but i can't figure it out, i've read some related posts but i don't know what to do, please help! https://forum.digilentinc.com/topic/18026-pin-assignment-problem-sd-card-pmod/ https://forum.digilentinc.com/topic/79-pmodbt2-bluetooth-functionality-implementation Here is the block design ( i have used the dilligent Digilent/vivado-
  9. Hi All, I am working with a ZedBoard trying to test the output functionality of the Pmod headers. The Pmod headers on this ZedBoard have worked in the past, however, when I try to work with them now it appears that they do not transmit any output data. I've tried this for all four programmable logic accessible headers (JA1, JB1, JC1, JD1). When I assign the output to the LEDs I am able to see the output successfully, but it does not come through the Pmod headers. Here is a very simple HDL file and constraints file that I'm using on my ZedBoard that should produce output on the Pmod h
  10. I am trying to interface PMOD DA4 with atlys FPGA but nothing is coming at output. help me to rectify what wrong with code. module spi_master_v1( input sys_clk, input rst, output reg cs, output reg MOSI, output reg sclk, // input [31:0] in_data, output reg done ); // Internal registers reg [10:0] count; reg [31:0] temp_data; reg [5:0] bit_count; reg [11:0] count2; // state declearation reg [1:0] state; parameter idle = 2'b00; parameter data_tx = 2'b01;
  11. Good morning, I'm an Italian engineering student at Politecnico di Milano, Italy. Currently, I'm working on my Master Thesis in Aeronautical Engineering. My Professor recently bought a couple of your Pmod NAV: 9-axis IMU Plus Barometer boards. I was wondering if you could kindly provide a 3D CAD model of the component. I looked on the dedicated page but unfortunately I wasn't able to find it. Thank you in advance for your consideration.
  12. 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

    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
  14. 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.
  15. 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!
  16. 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
  17. 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 <
  18. 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.
  19. 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.
  20. 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
  21. 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.
  22. 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?
  23. 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

    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
  25. 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
