摘要
文章分析了PC并行口和I2C总线的结构特点,提出了适合PC并行口特点的I2C总线接口方案。给出了PC并行口与常用I2C器件AT24C02的接口方法实例,介绍了用PC并行口模拟I2C总线控制时序的实现方法。实践证明,该方案硬件结构简单可靠,读写I2C存储器件的软件方便实用。
To analyze the structural characters of PC parallel socket and I2C bus interface and put forward plans suitable to the characters of PC parallel socket. To provide examples about the interface of common I2C and AT24C02. And then to introduce the methods of simulating controlled I2C Bus interface with PC parallel socket. Confirmed by practice, hardware structure used this experiment is simple and reliable. Furthermore, software is also convenient and practical to meet the market.
