摘要
简要介绍了I2C总线操作和基于Windows内核模式驱动的用户态I/O端口访问,分析了Windows平台下GPIO管脚模拟I2C总线的可行性,讲解了编程实现过程,连接I2C接口的安全芯片进行了验证。
I2C bus operations and user-mode I/O port access using Windows kernel mode driver are briefly introduced in this paper. And a feasibility analysis on simulating I2C bus with GPIO pins under Windows is made. Then we do a programming impelmentation to the simulating method, and verify the software by accessing an I2C-interfaced security chip.
