摘要
简要介绍了I2C总线的基本结构和规范、I2C总线接口芯片的基本工作原理以及I2C-Mas-terCore的工作原理,并着重介绍了在NiosⅡ上使用I2C-MasterCore实现对I2C接口芯片AT24C02读写过程,最后给出了C语言的编程代码。
The Ⅰ^2C bus interface is used comprehensively in electronic products. This paper briefly describes fundamental structure and specifications of Ⅰ^2C bus, basic operational principles of interface chip between I2C bus, and basic operational principles of Ⅰ^2C -Master Core. The procedure ofⅠ^2C interface chip （AT24C02） operated on Nios Ⅱ is introduced in detail. The C Language program code is offered finally.
