    Nexys4-ddr SD card

    Thank you Kaitlyn the tutorial on microblaze was very helpful for learning to use microblaze and the IP block design. Mahaita SPI should be sufficient for my needs so im sticking with it. So far ive managed to play around with the microblaze and the ip blocks and made this: it generates and bitstreams but i dont think it actually does anything. i think this would be the physical layer? i have no clue where to go from here or how to implement spi code to microblaze. ive seen the fatfs module for the file system layer but am unsure what i can do with it Ken

    Nexys4-ddr SD card

    Hi all, I'm currently working on a project, with a component to write an incoming video stream to a sd card. I was hoping someone could point me down a direction upon to implement a solution. I've looked into the SPI interfacing method. But am unsure how to implement it. I understand that i'll have to use microblaze to act as a processor for the image processing and what not but am unsure where to process forward. I have also looked into the native sd interface, but i am to understand that to do so would require licensing? Thank you for your assistance.

    Vmod+nexys 4

    That sounds great Hamster thank you for your generosity, however i will need to ask my supervisor if he wants to go down this path, so perhaps if you could send the design for your pcb we can get it made up if we end up using this idea. also if we did, i think we'd still need to use a cable to connect the cameras as the 2 pairs of of pmod headers are connected to the opposite ends of the board and for stereo imaging you need the two to be together

    Vmod+nexys 4

    Thank you Hamster for your insights, i am not to familiar with the Zedboard or even building the necessary connections for an adapter, hence looking for the most simple setup such as the VmodCam, i also have looked into the Atlys board but im being advised by the supervisor to stay with the Artix-7 over the older Sparten-6s. I'm also starting to learn VHDL and Verilog to program these FPGA and i'd like to try incorporate your code into the project when i understand it more. Alex i will definitely pass this on to a friend who can hopefully read this, however it looks very promising. espically the 0.3MP unit as this is the resolution and framerate we were looking at using. Else if the Nexys 4 board is unable to support these cameras, the supervisor is really pushing for the Xilinx Evaluation board but it is very costly or perhaps use a DSP as bridge between the camera and the Nexys 4 as the project will also require a DSP. Hence i'd also like to ask how would i go about connecting the Nexys 4 to a DSP? Thank you again.

    Vmod+nexys 4

    Hi all, I am a 4th year engineering student from RMIT university of Australia. I'm in the search for FPGA board for the purpose of generating a depth map via stereo cameras, as part of a larger project. What has caught my eye is the Nexys4-DDR board primarily for its Xilinx Artix-7 chip and upon further searching the Digilent store i so found the VmodCAM module which may be particularly useful for the project. However i am aware as to the fact that the Nexys4 board does not have a VHDCI port and hence would like to know of any work arounds to this issue, possible PMOD cameras or other ways to connect a pair of cameras to the Nexys 4 board. Thank you for your time and assistance.
