Sebbene il meccanismo di connessione sia importante per la progettazione del sistema, una volta collegato dovrai considerare la possibilità di inviare i dati da e verso i dispositivi, aggiornare il codice da remoto e monitorare lo stato di salute dell'intero sistema. E naturalmente non dimenticare la sicurezza.

Ma tutte queste cose sono solo comunicazioni digitali.
In effetti, qualsiasi cosa a cui il tuo processore invia byte attraverso un'interfaccia digitale ha un proprio processore.
