  1. Hello friends, I'm trying to implement ov9281 camera on my zybo z7-20, I'm using pcam 5C demo project, so far i have achieved damaged frames from camera(included pictures) can someone help me understand what's wrong with it, why its damaged? btw I'm using digilent's mipi IPs and on pictures you can see the highlighted spots are flashlights shining on camera.
  2. I am doing an image processing (not video) with Zybo Z7, and I am writing my own algorithm in C and C++ language for the image processing algorithm. For the simulation (without camera), I have some ready photos that can be loaded from SD card and then I want to test the performance of my algorithm on. I know Xilinx provide xsdps driver for the SD card, but I don't know how to use it for my project. But For the real application, the image processing will be done on the photos that are taken regularly by a camera. My priority, for now, is to first test my code using simulation
  3. Hi everyone, I am trying to connect an OV 7670 camera to my basys 3 board and program it so that it shows the live camera feed on a monitor connected to the VGA port of the basys 3. The only thing I was able to do is connect the camera to the pins on the basys 3. I've looked everywhere, including here, but cannot write the other components, like frame buffer, myself. I would appreciate any help or any suggestions about where to look for help. P.S. I have enough knowledge of VHDL and the basys 3 board to implement an adder that uses the 7-segment display. Thanks.
  4. HI, for my new PYNQ-Z1 to connect over its "USB HOST" interface: (1) will any USB Hub do, e.g., when concurrently a USB WiFi dongle and a USB-Webcam are connected to the PYNQ-Z1? (2) what is your recommendation(s) of a "compatible" stereo camera module (cf. attachment) for the PYNQ-Z1 board ? Thanks.
  5. Hello, I am working on a project using an Z7-20 FPGA for computer vision processing using a CMOS camera sensor. I am planning to run convolutions on the image data for usage such as a Sobel filter. (to avoid RAM requirements, I will most likely use a Line Buffer to store the data while it is in use. This means I will need a camera sensor which can connect directly to the FPGA and outputs one pixel at a time (through multiple wires for each color), with a well-defined (or customizable) clock to synchronize the data transmission. I want like something cheap, rugged, and easy to wire like the
  6. Hello! I have been investigating how multiple clock domains work and how you can send data ASAP from a camera module to a SDRAM (taking a pic). I am currently using a Nexys-Video and a Zed board and wonder if I could get some tips. The problems I encountered during my research is: -The picture I take has to be stored ASAP, meaning I have to use the mig7 interface for the SDRAM and HDL code. However this will be hard since it requires me to understand how the MIG7 works and thus writing a HDL that is adjusted to work with it. - What is the maximum f
  7. Hello, is it possible to sample an external analog signal using the XADC? Or do I need the AMS101 Eval-Card for that? I'm using the Sony XC-HR50 analog Camera (datasheet: https://pro.sony.com/bbsc/ssr/product-XCHR50/ ), which has a CCD Sensor. I am very new to Zedboard and trying do save the picture of the camera. Thank you, kind regards The Video Output is shown below:
  8. I'm trying to understand how to set up clocks and read data from a MIPI camera sensor. The sensor (Omnivision 5647) uses the MIPI CSI-2 protocol with D-PHY for the physical layer. The stage I am trying to get to is to be able to observer SoT (Start of Transmission) signals after which I can start parsing the CSI-2 protocol packets. In a small MIPI writeup located at http://archive.eetasia.com/www.eetasia.com/ART_8800715969_499489_TA_a466fca2_3.HTM there are 2 statements that are to be taken into consideration when trying to read data: "The high speed payload data from the transmitter i
  9. Hello everyone, I am using a Nexys 4 DDR for a school project. I am building a system that uses a video camera to detect and track human motion. Several questions: 1. Which port should I use to connect the camera? The immediate one available on the board is the USB host connector, but is it possible to use it to connect a camera? 2. Are there any PMODs available to connect a camera module? 3. Any recommendations for a specific camera model to use for this project? Basically, I need to take the video input, perform some filtering to recognize face and arms, downsample t
  10. Hello, I want to feed video from my smartphone camera to Genesys and want to display the video on the PC. I don't know how to interface. How should I connect my smartphone camera with Genesys board? I also want to do the same thing with Nexys 4 DDR board. Any kind of information will be helpful. Thank You.
  11. Hi JColvin, We used zybo for our board prototype integrated with OV7670 Camera. every time I run it. I have a warning like this: INFO: [Labtools 27-1434] Device xc7z010 (JTAG device index = 1) is programmed with a design that has no supported debug core(s) in it. WARNING: [Labtools 27-3123] The debug hub core was not detected at User Scan Chain 1 or 3. Resolution: 1. Make sure the clock connected to the debug hub (dbg_hub) core is a free running clock and is active OR 2. Manually launch hw_server with -e "set xsdb-user-bscan <C_USER_SCAN_CHAIN scan_chain_number>"

    Rpi Camera - FPGA

    HiI have been working with the Raspberry Pi Camera to make an interface with an FPGA and take the data from the camera to the FPGA memory. I want to connect the Camera Module directly with the FPGA but I have not found any document that explain the communication protocol or some procedure to make it possible to connect and configure the camera with the FPGA. If someone know any document or have an idea that can be helpful for my project I will be very grateful. Thanks.
  13. I plan to use Nexys video for image processing. I did a project before where the FPGA gets the data straight from the sensor but now I will be using one of the interfaces (HDMI, USB, etc). There is a number of options, probably any of them valid, I'm just asking for suggestions. The most available cams have USB interface but Nexyx does not have 'pure' USBs unless I'm wrong and I'm not that much willing having an embedded processor just to interface USB to my video format stream. Second thing I though was to use the HDMI input but can't find many cameras with that output... Of course I want to

    Nexys Video + Camera

    Hi, I have used Atlys + VmodCam for probing camera enhancement algorithms. This time, upgrading to Nexys Video + Camera is needed due to the termination of Atlys. Is there any suggestion for what kind of camera module is the best in the market? Jay
