摘要
主要介绍在单主系统中,利用单片机的通用I/O口来虚拟I2C总线接口,通过相应程序的设计,实现在无I2C总线接口的单片机系统中扩展具有I2C总线接口外围设备的目的。
This text introduced simulating I^2C (Inter Integrated Circuit) bus with ge4neral input/output in the system of single microcomputer.The chief object of which is to extend peripheral equipment with I^2C port by corresponding to program designed in the system of single microcomputer without I^2C port.
