单片机双机通讯，主机是用软件模拟iic，从机在硬件iic中断里面接收数据，单片机是2种不一样的MCU！-Single-chip dual-machine communication, the host is a software simulation iic, iic interrupt from the hardware inside the machine receives data, the microcontroller is two kinds of different MCU!

用51作为主机。ms5611气压传感器测量气压及温度并转化为高度，将数据用oled显示。包括软件模拟IIC及硬件SPI通讯方式。-With 51 as the host. Ms5611 barometric pressure sensor to measure air pressure and temperature and into a high degree, the data with oled display. Including software analog IIC and hard

该文件是使用软件模拟IIC通讯，由于硬件IIC通讯存在隐患，因此考虑到使用软件模拟IIC通讯来作为替换
