如果单片机里不带有IIC通信模块，是不是比较头疼？不用怕，我分享了一个基于IO口模拟IIC通信的C语言源代码文件，这个也可以适当修改IO口，用在飞思卡尔xs128单片机上，注意修改方向寄存器哦！-If the MCU is not in communication with the IIC module is not a headache? Do not be afraid, I share a communication based on IO port simulation IIC C-language source code files, this can also be appropriate to modify the IO port, the microcontroller used in the Freescale xs128, pay attention to modify the direction register Oh!
