  1. 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.
  2. Hi, I have a basys mx3 with a pic32MX370 I want to know how to write non-ascii caracters on the LCD. I want to make a Tetris game, but the LCD screen is only 2x16, so how to write very little caracters on the LCD, like one dot at the time. I guess I need to write at the accurate adress on the LCD, but how ? It could be done in assembly or C, I don't mind. I want to do something like the picture: Thank you.
  3. Hello, (FPGA board is Nexys A7 100T) So my end goal is to implement RC4 stream cipher and implement it onto FPGA. I was trying to configure a switch that will utilize the 7-segment 8- digital display and display my original plain text. And another switch that will display the encrypted text. I have attached the sources and test benches below that works. And have screen captured the simulation to show the results. Thanks for spending the time, I'll be high alert for response and try to respond on follow up questions. Can someone help me with this?

    SPI TFT Display

    Hello everybody. I recently got this SPI TFT display for my Raspberry Pi: https://www.conrad.at/de/raspberry-pi-display-modul-schwarz-rb-tft32-v2-raspberry-pi-a-b-b-raspberry-pi-1380381.html http://joy-it.net/tft-display-3-2-v2/ But I'd have more use for it in an FPGA project of mine. Now, I couldn't really find a pinout but as it's made for Raspberry Pi I could already figure out what lines are already reserved for power and with a little bit of luck, the MOSI / MISO / SCLK / Chip Select run on these pins: https://de.pinout.xyz/pinout/pitft_plus_35 I just wanted
  7. Hello, I bought the Nexys 4 ddr and the pmod oled (Pmod OLEDrgb: 96 x 64 RGB OLED ) display. I'm trying to display ascii text on the PMOD using the microblaze. I've gotten this up and running to the point where I can display lines etc... In looking at your resource center I still can't figure out how to print characters. How does this process work? I've figured out you need to define the characters in a "font" array and it looks like you use 5 bytes to create a 5x7 grid and the 1's determine what pixels are on there for allowing you to create the character. I'm confused as t
  8. Hi, currently, i managed to run linaro linux on my zybo by using this guide http://www.instructables.com/id/Setting-up-the-Zybot-Software/ inputs such as mouse and keyboard are working fine, however the touch input from my lcd display are not working (the touch input works in my windows computer, so its not the display which is broken) the touchscreen display is from eGalaxTouch or better known as eGalaxTouchscreen can someone kindly help me to solve this problem? thank you very much Regards, Lightning
  9. Hello Digilent community, I am currently taking my first digital electronics class and my final project is a calculator written in VHDL using a Basys3 board, 16-key keypad, and a 16x2 LCD display with parallel interface, all provided by Digilent. I took a look at the provided example code from the resource library and I just had some questions about how it works. Now, the example code declares a constant before any of the processes, and this constant is an array of std_logic_vectors so it holds a preloaded message "Hello From Digilent" with the necessary function sets and all that prec
  10. Hello, I've got some troubles while trying to fully understand the Zybo base system design. I need to replicate in my design (with Vivado 2015.4) the video part of the bsd, with the Axi display control ip. The design works but some points are not very clear to me: I've notice that 2 different clock sources are feed to the PL: (FCLK_CLK0 @ 100 MHz and FCLK_CLK1 @ 150 MHz). What is the reason behind this? Isn't 100 MHz enough for the VDMA? Why an Axi protocol converter is used? The design was build for an older version of Vivado (and ip library)? Thanks

    SPI

    Hi, I have PmodALS with basys 2. I need some example, in VHDL, to read data with the SPI protocol. I want to show the lectures on the 3 seven segments display of basys 2. thank you
  12. I realised a Vivado ip axi controller for basys3 4 digits display. You can find ip and test project here https://www.dropbox.com/sh/62c4uoar3lf9gzn/AABWfCCFOgShxkID7U6OjXdha?dl=0 It's easy to expand for nexys4 8 digit display. Actually the controller manage the number of digit to use in hex or bcd mode with the limitation of overflow. Dp are not managed. It will be helpful if Digilent can develop some ip templates for Pmod modules .... just a suggestion
