FPGA DE0-nano with RFS for serial communication

Hi, I'm new new new newbie using FPGA I am having difficulty in sending processed signal data using the DE0-Nano FPGA to my PC. I've read some suggested methods on this forum, one of which involves us...

Hello rosesea,


There is the document named RFD_UserManual.pdf provided in the link provided by @Farabi.

Have you check the document?


There are the RTL Example designs provided as well as the demonstration setup that you can follow and see if it can help you with your difficulty.


Regards,

Aqid

    Hai Aqid,

    Thank you for your advice. I have tried to search for demonstrations on the use of UART to USB, but I am having difficulty finding ones that only use UART to USB.

    Then, I attempted to use the DE10-Standard, which in its system builder has an RFS port declaration. I have also added the UART (RS-232 Serial Port) library to my platform design and created a program on NIOS II to send "hello world" with transmission configuration for the host PC as per the tutorial at https://www.youtube.com/watch?v=7xJ9dhVDCwU.

    There were no errors, but the "hello world" message did not transmit to the host PC. Is there any advice on what else I should ensure for my project?

    Thank you,

    rosesea

      If you are using NIOS II in your design, Intel UART IP is a reasonable choice. Don't know why your test doesn't work.
      For designs without soft processor, I'd prefer a simple fixed baud rate UART module. I'm not aware of suitable Intel IP, but there are many examples on the internet. I'm usually writing it from the scratch. It's basically a shift register, a baud generator and a state machine.
