  1. Hi, Problem : I am new to FPGA and I would need to understand how to read an Analog input through the XADC to analyze it on the board and then be able to accordingly output a trigger for other machines. One simple thing that I would try to do for the time being is to read in the analog signal and wire it to a led so that I could effectively see the code is working. How do I do that ? Finally, one extra constraint is that I have to limit as much as possible the use of the Zynq processor (I'm not really sure this is achievable, please excuse my lack of knowledge). Product : I use the Zybo Z7 board XC7Z010-1CLG400C and Vivado Design Suite 18.3 What I have tried : I think the tutorial I've seen that best suits be needs is this one : https://cdn.instructables.com/ORIG/FRT/SYN1/IWMMH04D/FRTSYN1IWMMH04D.pdf Everything is alright until it comes to copy the instantiation template into the wrapper. I'm not really sure of how this works. After that, it is said there that the Digital input I'm interested in is named "daddr_in" ==> how should I extract it then to - let's say - connect it to a led ? Please find the Constraint file and project in the attached files and let me know if you need more. I have also made other attempts through this : http://realisenow.sdu.dk/using-the-xadc-on-the-zybo-board/ Hence a question on the fly : when I open the SDK and enter a code in C, then I'm starting to ork on the PS isn't it ? Finally, I have also tried the XADC demo project on the digilent website but couldn't sort out how to adapt it to my needs. Thank you in advance for your healp, !

  2. Hi, I am new to fpga. I am trying to read/write from sd card zusing the zybo zynq 7000 and I found the Xillfs example. For some reason the mkfs function always fails. I don't know if there is a problem with my design? I have enabled the sd0 in zynq processing system. Is the something else I should do? Any help is appreciated.
  3. Hi All, I'm working on a project that requires me to read a file from a PC (mac, windows, or linux), or external thumb drive onto Xilinx Zybo Z7 board. The communication does not have to be over USB however it does have to be able to read a file either on a USB or a Computer as well as write to that same device. I've looked at several different forums and can't find anything that would make this seem doable. Any help in this matter would be greatly appreciated, thanks for your help. If you could provide an example of a small working project that would be immeasurably helpful.
  4. Hello everyone! Someone knows how read and write files in the SD card from Standalone application in SDSoC? I think that I have to set up the option in the BSP but i am not secure, and i don't know how do this. Thanks for your time, Raúl.
  5. Hey all , I am taking a continuous 16 bit serial input from an AFE to nexys 4 ddr board and storing it . Now I have to take this data to pc using usb . I have been searching for this for a long time now (2 weeks to be exact ) but could not find any simple solution . I am using ISE design suite 14.7 VHDL for programming. This is my first fpga project, so please bear my incompetence. Thank you
