A mechatronic system comprises an electric actuator for driving a mechanical member, and drive electronics for controlling the actuator associated with a position sensor including at least one magnetosensitive probe including a programmable digital switch delivering an electrical signal dependent on the angular position of the mechanical member. The drive electronics comprise a microcontroller having at least one wake-up mode corresponding to the activation of the microcontroller only by a programmable wake-up circuit. The position sensor comprises a programmable wake-up circuit delivering a signal to a bus in the event of the mobile member moving. One of the microcontrollers controls, upon activation by a wake-up signal transmitted by the programmable digital switch: initialization of the access control register for controlling access to the EEPROM memory, writing of a digital datum to an EEDATA register of the EEPROM memory, and switching to rest mode at the end of a predetermined period.
