Abstract:
1. A method for communication between a master module and a number of slaves coupled to a bus over which the slave modules communicate simultaneously with the master module according to a serial communication protocol of the priority logic state type, the method comprising: receiving a plurality of successive packets of 2p-bit digital words at the master module, where p is greater than or equal to 1, the successive packets being respectively associated with successive groups of p digital information bits associated with the slave modules and intended to be communicated to the master module, the 2p bits of a current word of a current packet being respectively associated with the 2p possible combinations, taken in a predetermined order, of the values of the bits of the group associated with the current packet, the value of each bit of the current word having the priority logic state if the values of the p bits of the digital information item of at least one of the slave modules correspond to the combination of values associated with this bit, and the other logic state otherwise; and determining by the master module of the values of the bits of the digital information items associated with the slave modules on the basis of the values of the bits of the words successively received.
