Communication PC-DE0 Nano using UART

1,152 Views

Hello everyone,

I'm trying to connect my FPGA with my laptop using the serial protocol. For that purpose, I implemented the UART protocol on the FPGA side.

The connection between the FPGA and the Laptop is done with the UART-TTL to USB converter. I Get the wrong frame on the Laptop side.

Thus, I analyse my frame continuously using a logic analyzer, I observed that the frame sent wasn't stable, i.e sometimes a wrong frame is received instead of the one sent.

Thanks for you help.

please find attached the source code for the Serial code(TX.vhd) and the control unit (UART.vhd)

Best regards,
