摘要
文章在介绍I2C总线的接口和数据传输格式的基础上,着重论述了平流泵的工作原理和基于I2C总线的24LC02型E2PROM与89C52单片机的物理连接及读写操作过程,从而实现了其相关参数在串行存储器的存取,确保了该仪器的精确度。
The interface and data transmission format of the I2C Bus are introduced firstly.The work principles of the constant flux pump and the physical connection and read-write processing between 89C52 microcontroller and 24LC02 E2PROM based on I2C Bus are discussed emphatically.Thus,the access of correlative coefficients from the serial memory unit is realized,ensuring the precision of instrument.
