  1. Hello, I have had OV7670 design working on older Spartan design that would like to bring into ArtyZ7. I had purchased from Digilent some Z7 boards to get started with upgrading some of our designs. I seem to have some difficulty to convert the RGB data to HDMI output. I believe issue is with HDMI VHDL, specifically looks like timing. The HMID output is attached. When I move object near and far from camera, I can see changing intensities in the "noise". OV7670 is running at 25MHZ/50MHZ clks. I am using 125MHZ for the HDMI - out module to convert the RGB data to tmds.

    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

    Altium Files

    Hello, Yes, I somewhat anticipated this response. The company i work for would be interested in such a boot strapping design. If there is some NDA we could have signed, or some other recommended pathway than starting from scratch, I would appreciated. I have done this in the past with Spartan -3 design , and would like to avoid doing again very tedious stuff. Best Regards,

    Altium Files

    Hello, I am working with Arty A7 and Arty Z7 dev boards with various PMODS building up a platform for imaging readout. While these are useful getting started, I will soon need to roll out a board with some customized routing. I notice many of the schematics and design files are shared in pdf. Are any of these schematic/layout files avialble in Altium for boostrapping some of these custom designs off the open source boards? This would really help accelerate FPGA design projects. I noticed Altium has some open source daughter boards, but this would be a better solution. If th

    PMOD NIC100

    Hello, I am working with arty A7 and arty Z7 dev boards purchased through your website. I have downloaded IP files from github . However I when I import into Vivado (2018.2) I am not finding the NIC100 PMOD . Several of the other PMODS are working and verified. However, I am not finding the NIC100 PMOD in the add IP , even after digilent library is imported. Can you send me to correct github location that contains this file?

    Hello, I am working on integrating ESP32 PMOD into a vivado 2018.2 project. I have imported DIgilent IP library into Vivado. When I place PMOD and connect to board, during compilation. It is actually a general message from the block design (See attached image). It apperas to me that this IP is for ArtyZ7? or some other Zync product? If so, is there IP available for Arty A7 or is this message to be ignored?
  7. Hello, Thanks. Yes I am familiar with basic demos at this point and am trying to move onto more interesting projects. I have implemented this demo but it seems to be all written in vivado HDL, with which i have a fair amount of experience coming from ISE. I was looking for some additional resources for SDK side. But now that I consider, perhaps even the firmware that the ArtyA7 comes pre-loaded with is likely to be pure HDL. We can close this question. Thank-you for your attention, it is much appreciate.
  8. Hello, I am working through some of the examples for the Arty A7 device. The device seems to come pre-loaded with firmware, some simple reference design that makes use of UART, LED's and pushbuttons. Is there some project I can download to reproduce this reference design? I am planning to overwrite this in the future, but I also wanted to have a copy. Thanks

    ZedBoard PCAM

    Well Thank's for your support. I will be working on several other projects trying to get them up and running. I think this was important. One question that remains in my mind however, is how to determine if the drivers need to be imported from the ip_defs folder or not when working with various IP. It was not very straightforward, as several other IP were using "generic" and didn't seem to cause a problem. The two that we selected seemed somewhat non-intuitive. I am wondering when this kind of thing will come up again, and I will need to handle. Thanks again.

    Hello, Nice. Works. no 3.3V jumper necessary. For some reason the SDK was not populating the main.cc file with any of the driver information needed. Now when I have recompiled form start, the main.cc file comes back with much more data. I don't think I fully understand the source of the error. It could have been includes. But the project is indeed functioning now. Thanks!

    OK. I will re-run. While Re-reading the first line though this reminded me of another concern I had. It requests placing jumper on 3V3, however, no pins were soldered. Should I manually short these and remove the 2.5V jumper? If that 3.3V is used or powering camera, I am wondering if this could also be impacting. Please let me know. Meanwhile, I will continue to re-build.
  12. Ok. Will go ahead and pick up a couple of those for our team to develop with. I will still be looking to get the other demos working with the ZED, however, there seem to be several interesting projects that could be useufl for our end application using ArtyZ7. Thanks for your quick, clear, concise responses.
  13. I see. So is zed dead? I frankly don't see alot of activity on this board to use for reference designs. Many links are broken. Would you suggest Arty Z7 for zynq development projects as a more up to date development board? Another board? One project we have in the works will be driven by Zynq and would like to have as many examples with PMODS / peripherals as possible. Thanks, Jerome

    Hello, I have actually tried to do both. For C++ i wrote a similar 'Hello World' example to make sure it is getting compiled. Unfortunately, I am seeing Hello World, but I am not seeing VGA output on the monitor. Does this imply there is some issue with bitstream? BTW, this is Digilent Board with FMC PCAM adapter purchased online through Digilent Portal.

    Hello, Thank-you for that clarification. I must have skipped that when I was building the demo. As seen below, I have updated the folders, and the drivers are updated. I am also recieving "Hello World" over com port. Regardless, VGA signal is not showing up on my monitor. Any other suggestions ?.
