Are you talking Rasberry Pi ? If so certainly, via USB on e way.
Or on forum some folks have done web server solutions you
can look at, note external MAC/PHY would be needed.
Or UART to Pi, or simple bit banging a serial link between boards.
Look at this PSoC4-M board.
The PSOC 4M family does not have the DFB (Digital Filter Block) which I
think you plan on using. Thats only in PSOC 3 and 5LP.
Thank you so much for your valuable answers :)
