UART 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,
