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...

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.
