  2. what is boot loader?

    hello how does boot loader work?
  3. How to make led wall with FPGA?

    i have seen i don't understand it coding?
  4. how to build satellite for radio communication?

    hi I have seen processor what does they do which battery they used?
  5. Matlab for AD2

    I'm not sure if this is the right area! BUT, I'm trying to use matlab to control a DC motor for the purposes of control labs at a university. So far I have found that MATLAB is very limited with its functionality when it comes to the AD2, which is not good for me...... Does anyone know if MATLAB's Simulink has functionality to run both an output and input from an AD2? doesn't seem to work with both! this is not good for control. My other option was to just write the MATLAB code and put it into a GUI, again MATLAB appears to be quite slow when it comes to sending the information out to the motor. Any advice or examples would be appreciated, I'm also looking at labview, but I MATLAB is preferred!

  7. AXI Stream FIFO

    Hi @newkid_old, also how often you getting a full packet from the FIFO? thank you, Jon
  8. AXI Stream FIFO

    Hi @newkid_old, What is the clock frequency you are giving the AXI Stream FIFO? thank you, Jon
  9. AXI Stream FIFO

    80Mhz is my target speed.
  10. AXI Stream FIFO

    Hi @newkid_old, The AXI Stream FIFO looks to be the best Memory device for your situation. Also to clarify what frequency are you planning on moving data from the ADC? thank you, Jon
  11. MAX 32 Bootloader

    Hi @KStock, I think I found the solution/work-around, but unfortunately, it seems to be a hardware problem that will involve cutting a trace and seems to prevent the use of the SD card slot. The thread (and corresponding threads that it linked to) are on the chipKIT forum back from 2011 with the main one here, and the discussion about what the issue is on this thread here, which goes on for a couple of pages until you see the post that is referenced in that first link. I do not have the Arduino Ethernet shield to test this (and the Digilent person on those threads retired a number of years ago), but looking at the Max32 hardware I have now and seeing the date of the Arudino Ethernet shield schematic (2010 is what I'm seeing), I do not think that a hardware board change has been made or a software change has been found. Thanks, JColvin
  12. AXI Stream FIFO

    I have an ADC that outputs a new number on the rising edge of a clock. I want to store x number of samples, for now say 128, then read them into my Microblaze and spit them out over UART.
  13. AXI Stream FIFO

    Hi @newkid_old, Could you clarify what you mean by storage device and what your project is? thank you, Jon
  14. AXI Stream FIFO

    I suppose I should have framed this as a question. Whats the best method to clock data in to a storage device? Xilinx has a few choices and I'm not sure which is the best.
  15. HDMI In to VGA out on Zybo

    Hi @cgarry, We currently do not have a basic project with these ip cores that does not have a processor involved. I have reached out to more experience engineers about your thread to see if they have any other input. Could you please attach your time errors? thank you, Jon
  16. I finished step 36. On this forum, mffrac downloaded a pre-built ramdisk8m.image.gz file over at: According to this page, it says to use -C instead of -c to specify to compression type. I still don't completely know how much functionality I will get with only a ramdisk. Frank
  17. MAX 32 Bootloader

    Sorry - I am not using your shield - it's retired. I am using the Arduino Shield (see attached) I do have another board (ARINC 429 Board by HOLT) attached to the SPI bus but with it removed, still have the bootup problem. A000056_DATASHEET.pdf
  18. SPI_SLAVE_intr_example not working

    Hi @rahulgujaran, I would suggest to scope the external pins along with using the SDK debugger to better see what is going on. thank you, Jon
  19. how to build satellite for radio communication?

    Hello! I'm not trying to be an internet troll and perhaps I'm misunderstanding what you mean by satellite, but I suspect most of them are some expensive military grade processor that isn't very user friendly. This website seems to list some processors that have been used but it hasn't been updated in nearly 6 years... On the other hand though, what exactly does a satellite have to do with Digilent products considering this is on a Digilent forum instead of something like stackexchange or reddit? ~Natsu
  20. How To Program The Quad-spi Flash On The Basys3.

    Hi @Ankit, We responded to your question on your other thread here. thank you, Jon
  21. zybo: lading bit file to SPI flash using Vivado

    Hi @Ankit, You can also erase the flash with the hardware manager in Vivado. You could make your own custom application to do this with Adept 2 sdk thank you, Jon
  22. Zybo HDMI untouched design not meeting timing req.

    Hi @Casio342, For confirmation of getting the project working, it may be good to test out the project in Vivado 2016.4 since that is what it was designed in. thank you, Jon
  23. How to make led wall with FPGA?

    Hi @Riteshkakkar, I have not made a led wall for video purposes. Here is a link to FPGA4FUN dealing with led displays. Here is a led display we made for the snake game. thank you, Jon
  24. MAX 32 Bootloader

    HI @KStock, Looking at the schematic for the Ethernet Shield that Digilent has (link), there shouldn't be any connections to that MCLR line. Are you using the same ethernet shield that I linked to? The other thing that can cause this reset (on any PIC32 device with this USB/FTDI setup) is if a new USB connection or COM port is established; this can be a serial terminal opening, flash drive being plugged in, another PIC32 board, etc. Is anything like that happening in your setup? Thanks, JColvin
  25. Transform pins into Pmods

    Hi @tester11, You can use pin IO0-13 and A0-A11 as shown in the reference manual in section 16. All of the pins on the pmod ports are connected in the Arty-Z7-10.I do not see an issue with your third GPIO. thank you, Jon
  26. Arty Artix-35T complete xdc

    Hi @Trillian, The master xdc is here. The pins that are not in the xdc are accessible in the schematic here. The power and ground pins on J7 would not be accessible pins connected to the fpga. You are correct with the vp and vn pins being k9 and j10. thank you, Jon
  27. Infos about MAX32

    Hi @Dan84, I believe you only have to connect the Max32 to the PC via the PICKit (or similar) and then you can flash it with the desired code, yes. If you want to load the original bootloader, it is available for download on the Max32 Resource Center on the right hand side under Design Resources on our Wiki here. Let me know if you have any questions about this. Thanks, JColvin
