Occasional ContributorUART receiver loopback characters VHDL
Hi Tex,
You may check on this first example design link:
https://github.com/Domipheus/UART
https://domipheus.com/blog/a-uart-implementation-in-vhdl/
Make appropriate connection between O_tx and I_rx to form a loopback. The simulation result like below:
This is second example design link (apparently state machine):

Make appropriate connection between o_TX_Serial and i_RX_Serial to form a loopback. The simulation result like below:
Thanks,
Best Regards,

Occasional ContributorThanks for your reply,
I'm a student, I would like to learn UART with fpga in VHDL
loopback what i mean is, if i enter in the keyboard any character it should display in the serial monitor
i'm thinking state machines are tough to learn
please help me with any kind of tutorials where i can learn it or any codes
best regards,
Tex
Frequent ContributorThe concept of 'state machines' is not hard to learn, and in fact is indispensable when it comes to digital design in general.
So I suggest you pursue learning state machine concepts, be it graphically or encoding the state machine into VHDL.
It will make your life so much easier and more enjoyable when it comes to using FPGA technology.
Here is a simple tutorial centered around using VHDL (I am a verilog guy myself):
There are lots of other tutorials on the web and youtube.
