| 摘 要： | MCS51系列单片机不带I^2C总线，而许多接口芯片，如存储器芯片、显示驱动、A／D、D／A等接口芯片．由于小型化，低成本需要．采用了I^2C串行总线接口，这限制了I^2C总线接口芯片的使用。本文主要介绍I^2C总线结构、基本特征及时序．通过自行设计的数据采集系统，介绍新型的带FC总线的存储芯片FM24C64。通过软件模拟的方法。实现I^2C总线在MCS51系列单片机上的应用。

| Abstract: | The MCS51 Single Chip Microcontroller family does not provide an I2C,but many I/O IC,such as the Memory?LCD driver?A/D ?D/A IC, provide an I2C, because of small set and the law cost.That limits the application of the IC which provide an I2C. Letterpress mostly introduces that frame of I2C?the basic stamp and the clock period. And introduces an data gather system which design oneself and the new-style memory IC-FM24-C64 which provide an I2C, this memory IC is used in the system. In order to implement the application of I2C-Bus to MCS51 Single Chip Microcontroller family, it is necessry to use software to simulate the operation of an I2C. |
