Method of addressing a plurality of microsystems which can be individually addressed by a control circuit, the control circuit and each microsystem comprising electromagnetic transmission means, each microsystem comprising a counter and having an addressing code, an addressing phase of the microsystems comprising transmission, by the control circuit, of successive increment signals, each microsystem monitoring resetting of its counter and, upon receipt of an increment signal, incrementation of the content of its counter, and each microsystem comparing the content of its counter and its addressing code, so as to trigger execution of a pre-determined command when the content of its counter and its addressing code are identical, method wherein, the microsystems forming an array of microsystems, each microsystem comprises an identification code, in a read-only memory, and the method comprises an initialization phase successively comprising, for each microsystem, addressing, by the control circuit, of the microsystem by its identification code and storing of a reduced addressing code supplied by the control circuit in a register of the microsystem.
