摘要
MCS-51系列、MCS-96系列等单片机由于都不带I2C总线接口而限制了其在I2C总线接口器件的使用。文中介绍了I2C总线的特征和时序,并以串行E2PROM为例,给出了在51系列单片机上使用并行I/O口实现I2C总线接口的硬件电路和相关软件程序。
The paper introduces the character and time sequence,and,giving serial processor E2PROM as example,presents the hardware circuit and its software program of the bus interface I2C implemented with I/O lines within the single chip processor of series 51.
