A management method is described for a bidirectional and simultaneous exchange of digital signals between at least a first device (X) and a second device (Y), both provided with a corresponding interface (TRX, TRY) and interconnected by means of at least one connecting wire (C), the method comprising the following phases: - sensing a voltage level of the connecting wire (C); - sensing a current supplied to the connecting wire (C) by the interface (TRX) of the first device (X); - local reconstruction of a logical level transmitted by the interface (TRY) of the second device (Y) by means of a logical recombination of the voltage level sensed on the connecting wire (C) and the logical level transmitted by the interface (TRX) of the first device (X), depending on the current supplied by the interface (TRX) of the first device (X) to the connecting wire (C). Examples are also described of an interface for a bidirectional and simultaneous transmission of digital signals and a system for a bidirectional and simultaneous communication suitable to implement the management method according to the invention. |
