  1. Hello Digilent Community, I am working on a image processing project and was wondering if anyone had advice or could point me in the right direction. I have tried following some tutorials and example projects, but I am still trying to wrap my head around Xilinx Vivado and SDK. The project really shouldn't be very difficult, I think I am just missing some information or the best way to go about doing it. For the project I am using the Zybo z7-20 development board and want to save two images to an SD card. The two pictures are black and white frames from a video just seconds apart, so
  2. Hello, now i have installed a Linux vm with petalinux on my Windows host PC. To begin my work i tried to create a petalinux Project with: petalinux-create -t project -s /home/username/projects BSP file is: Petalinux-Arty-Z7-20-2017.2-2.bsp /home/username/Projects is the path to the given BSP file; when i execute this command then i got the following error message: "ERROR: No PetaLinux projects found in the BSP /home/czymic/Projects!" What must i do to create a new petalinux Project? Must i always use the given BSP-file or can i create an own bsp file? How can i ac
  3. Hello! I get the following error when I am going to run the createproject.tcl. Do I have to download an earlier version than 2017.3, if so is there a way to not do it since it takes me a lot of time to (uninstall and install) different versions. The error is: [Board 49-71] The board_part definition was not found for digilentinc.com:nexys_video:part0:1.1. The project's board_part property was not set, but the project's part property was set to xc7a200tsbg484-1. Valid board_part values can be retrieved with the 'get_board_parts' Tcl command. Check if board.repoPaths pa
  4. 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
  5. I'm getting these errors when trying to run synthesis a demo project from the arty resource page. On that page I tired doing the XADC. i did get it to generate the .tlc file stuff to make the project I did download the board files for the arty and placed them in the boards_files directory. but maybe it's not implemented correctly or im missing something. Some xilinx forums said to click on the "open block design" to fix this but mine is grayed out and I can't select it. Most tutorials online show the old Vivado UI the 2017.1 seems to be slightly different. mostly likely due to the missing
  6. i need a simple project in that zynq ps read dada from a ip counter can you help me?
  7. Here's a game of tic tac toe in VHDL for the Nexys4 DDR, written as a set of finite state machines and not as a computer running a program. The design is inspired from John F. Wakerly's tic tac toe code from his book "Digital Design: Principles and Practices", but I've completely rewritten it. The game logic is contained in the files TTTdefs.vhd, TwoInARow.vhd and game_logic.vhd. The rest of the code is there to interface with the user: to print strings to the user, to get digits and to control when moves are made. There are also two UART driver components. You should be able to set this up as
  8. I finally got some time to design my own Color Invaders project, originally inspired by Hamster's own Colour Invaders project. I ended up writing a lot of my own code for it since I have a personal thing about using somebody else's code in it's entirety, although Hamster's code obviously has a heavy influence on it's overall construction (thank you for posting it!). This game is similar to the classic Space Invaders game, or more closely related to Casio's Number Invaders on the calculator, where you have a stream of incoming invaders of a variety of colors coming down the WS2812 LED strip and
