摘要
The invention relates to a device comprising an array of microsystems which can be individually addressed by means of electromagnetic transmission, and to a method of addressing one such device. According to the invention, the microsystems (2) communicate with a control circuit (3) by means of electromagnetic transmission (4, 5, 8), preferably by radio frequency. The addressing method initialisation phase comprises the following successive steps, whereby: the control circuit (3) addresses each microsystem (2) with an identification code which is unique thereto, and a reduced addressing code (C) which is supplied by the control circuit (3) is stored in a register of the microsystem. Moreover, a subsequent addressing phase is performed, whereby the control circuit (3) transmits reset signals and increment signals to all of the microsystems (2). Each microsystem (2) controls the resetting of at least one counter upon receipt of a reset signal and the incrementation of the contents of the counter upon receipt of an increment signal. Furthermore, each microsystem (2) compares the contents of the counter and register thereof, such as to trigger the execution of a pre-determined command when said contents are identical.
