| Abstract: | I2C BUS and Flash Microcontroller are introduced,the principle and method of the application of I2C BUS to data collection system are investigated.The structure of I2C BUS is described and the data transfer on I2C BUS is analyzed in detail.By an example,the implementation schemes to connect the serial E2PROM to the Flash Microcontroller is proposed.The design of hardware is directly facing AT89C2051 Flash Microcontroller of the series of AT89,and the serial E2PROM can be substituted with the AT24C16.The research proves that the application of I2C BUS to data collection system is expediently,agile,high efficiency and feasible.I2C BUS can be applied to the different fields widely.The content introduced by this article is valuable for the application of I2C BUS. |
