[★ STMAN ★]

Hello.

I saw a fully ‘hardcoded cabled logic’ (No processor) Verilog code doing an USB->UART converter on OpenCores.

It may be a very good free alternative.
And from far, this approach being also the most secure one, regarding to the problems Benedikt mentioned in the last message.

Stman.
