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

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. Includin

MCU：R5F10268 编译环境：Cs+ 软件模拟IIC通讯，应用程序与驱动程序分开，可以移植到其他单片机上。已经测试验证过。(MCU: R5F10268 compile environment: Cs + Software simulation of IIC communication, application and the driver separately, can be transplanted to other
