Abstract

E' descritto un circuito d'interfaccia tra un apparecchio elettrico (PS) e una linea (L) di comunicazione di dati in forma seriale che comprende un microcontrollore (MC) e mezzi circuitali di ricezione (RIC) e di trasmissione (TR) atti ad accoppiare alla linea (L), rispettivamente, i terminali di ingresso dati (RX) e di uscita dati (TX) del microcontrollore. Per poter utilizzare un microcontrollore (MC) privo della funzione di "interrupt", il circuito comprende un rivelatore di picco (D3, C6) nello stadio di ricezione (RIC).
