Electron system using bus between integrated circuits as interface and its data transmission method

An electronic system using inter-IC (I2C) bus as its interface and its data transmission method are disclosed. Said electronic device is composed of an inter-IC bus, multiple slave devices with same bus address and coupled to the bus, a master controller coupled to the bus for transmitting and receiving data, and a selector for choosing one from said slave devices. 一种使用集成电路间总线(I#+[2]C总线)为接口的电子系统及其数据传输方法，包括一集成电路间总线；多个从属装置，耦接至该集成电路间总线，且该多个从属装置具有相同的一I#+[2]C地址；一主控装置，耦接至该集成电路间总线，用以接收及发送数据；以及一选择器，耦接该集成电路间总线及该主控装置，具有多个输出端分别耦接至该多个从属装置，从该多个从属装置中选出一个，以配合该主控装置进行数据传输。
