本程序实现了用TI LM3S系列单片机的IO端口接入I2C总线，可以实时监控总线上的变化与传输，并将I2C传输的内容，实时通过串口打印出来，可用于破解各种I2C通信协议，曾经用于解析PIC单片机之间的I2C通信，解决了串口实时打印的问题，采用FIFO，UART接受与发送均采用中断，并解决了FIFO中断深度等等问题。仅供参考。(This program is used to achieve the IO port access I2C bus by using TI LM3S Series MCU, this program can detect the change and transmission of I2C bus, and real-time monitoring the bus, and real-time print them out through the serial port. It can be used to solve all kinds of I2C communication protocol used for communication between I2C ,for example on the PIC microcontroller. To solve the problem of serial real-time printing, using FIFO on UART, and receive and send all by the interrupt, and the problem of the depth of the FIFO interrupt in the program.
