Abstract:
1. An interface for communication between sensing devices and an I2C bus, said interface comprising: a conversion module that converts an analog signal to a digital signal, wherein an input of the conversion module is connected to the sensing device to measure a given magnitude, and wherein an output of the conversion module is connected to a buffer memory module; wherein the conversion module contains an asynchronous analog-to-digital converter with an output signal generated at irregular time intervals, wherein an output of the asynchronous analog-to-digital converter is connected to an input of the buffer memory module, and an output of the buffer memory module is connected through an internal bus simultaneously to a source address module, to a configuration registers module, to a control module of an interface, to which a reference generator is connected, and to a destination address module, to a selection register module, to a transmitter/receiver module, and wherein control inputs/outputs ( wherein the transmitter/receiver module output is connected through a data line controller to a data line of the I2C bus having a clock line that is connected through a clock line controller to an output of the clock control module, and wherein a write control output of the asynchronous analog-to-digital converter is connected to the write control input of the buffer memory module.
