Abstract
A method for sharing data between a microcontroller and a plurality of driving circuits of actuators is disclosed. A microcontroller is provided with a microsecond bus and a plurality of chip-select outputs. A plurality of driving circuits have input pins for data signals received from the microcontroller through the microsecond bus. Each of the driving circuits has an input pin receiving a signal from a chip-select output of the microcontroller and at least two configuration pins connected to the ground voltage or to a supply voltage. A data frame signal is sent on the microsecond bus. Each of the driving circuits is supplied with a portion of the data frame signal as a function of the chip-select output of the microcontroller and as a function of the voltage connection of the at least two configuration pins.
