目前,MCS51系列、ATMEL89系列、68HC05系列等单片机应用很广,但他们均没有I2C总线接口,限制了在这些系统中使用具有I^2C总线接口器件的应用。本文介绍了基于I^2C总线的A/D转换的接口电路设计与编程,在Proteus仿真环境下建立单片机系统电路模型,实现了基于I^2C总线的A/D转换测试过程的虚拟仿真。

At present,MCS51 series,ATMEL89 series,68HC05 series microcontroller applications is very broad,but they did not I^2C bus interface,limiting the use of these systems with I^2C bus interface device applications.This paper introduces the interface design and programming of A/D conversion based on I^2C Bus and the model for MCU system under Proteus simulation environment.At last,simulation wa...
