I2C总线接口协议设计与FPGA实现

摘要

本文简单介绍了I2C总线的基本原理及数据传输协议规范，提出了一种I2C总线接口协议的FPGA设计方法，结合卫星导航终端设备，给出了试验结果，实际应用效果表明，本设计方法合理有效，满足卫星导航终端设备热启动需求。%The basic principle and data transmit protocol of I2C bus are simply introduced in this paper, a design method of I2C bus interface protocol based on FPGA is presented. And according to the satellite navigation terminal equipment, the experiment result is given. The actual application effect proves that the design method is reasonable and effective, which can meet the demand of hot start in satellite navigation terminal equipment.
