The method applies to an electronic module comprising a gateway to a communication bus suitable for receiving digital signal frames comprising, in particular, a frame-identifier field and a data field, an identifier discriminator being provided in the module in order to authorize the acquisition by the latter of the data contained in frames comprising a predetermined identifier, this discriminator comprising a memory zone assigned to the latter. A signal frame, the data field of which contains the predetermined identifier, and the identifier field of which contains an image of the initial state of the memory zone, is initially applied to the gateway of the module to the communication bus, in such a way that the identity then established by the discriminator between the initial content of this zone and the identifier field of the frame, authorizes the loading into the said memory zone of the predetermined identifier inscribed in the data field of the frame. Application to an assembly of interconnected electronic modules in a multiplex communications network placed on board an automotive vehicle.

Method of personalizing an electronic module and electronic circuit and

Device for controlling the electrical power supply of a stepping motor

The process and the device enable the electrical powering of a circuit having a conductor (1) with high thermal inertia by means of a transistor (3) with low thermal inertia. According to the invention, the device comprises a current limiter circuit (4,5,7,11), a voltage detector circuit (8) and a control microprocessor (6) which, according to a pre-established program, controls the flowing and stoppage of current in the power transistor (3) controlling the powering of the conductor (1) with high thermal inertia. Application to the control of lights in automobile vehicles.
