摘　　要：文章在深入思考分析和反复测量鉴定与跟踪仿真的基础上,找到了片内集成接口驱动合适的操控点并及时发出了操控指令,借鉴了成熟GPIO模拟IIC的操控,最终实现了STM-MCU-IIC硬件接口全面可靠高效的驱动,既提升了功能和性能还充分简化了驱动设计,使"弃之可惜"的闲置片内IIC得以高效运用,弥补了GPIO模拟IIC"得不偿失"。The paper based on deep thinking-analysis and repeated measurement-identification and A large number of tracking simulation,searched out suitable control-time-point for hardware-driver,timely issued control-command,draw lessons from ripe GPIO-simulating-IIC,finally realized reliable-efficient-simple driver for IIC on chip.It can use efficiently spare IIC on chip and can make up for the deficiency of GPIO-simulating-IIC.
