I^2C总线测试系统的设计与实现

Design and Implementation of I^2C Bus Test System

针对I^2C总线通信直接测试方法不足问题,提出了一种I^2C总线测试系统的方案,设计了一种具体的I^2C总线测试系统。I^2C总线测试系统可实现对任意通信协议的测试,同时可根据被测单元通信模式的需要完成主从通信模式的自动切换。实际应用表明,测试系统可快速完成对被测单元的I^2C总线通信协议测试,缩短驻留应用的I^2C通信协议开发周期,降低开发成本。

Considering of that there is insufficient method for testing I^2C bus communication directly,the I^2C test system proposal proposed forward.A specific I^2C bus test system is designed.The I^2C bus test system can meet the requirement that any communication protocol shall be test, and the I^2C bus test system proposal can realize master/slave mode switch automatically according to the requirement of units.It has been proved in practical application that test system can complete the I^2C bus communication protocol test efficiently.Test system can shorten hosting I^2C communication development lifecycle and reduce the cost.
