说明：  通过I2C接口读写EEPROM 在本项目中，我们利用Verilog HDL实现了部分I2C总线功能，并能够通过该总线对AT24C02进行读写操作。为了便于观察读写eeprom的结果，我们将读写的数据同时显示在七段数码管上，并设定读写的数据从0到255不断循环，这样就可以方便进行比较。
(Through the I2C interface to read and write EEPROM in this project, we use Verilog HDL to achieve some of the I2C bus function, and can be carried out through the bus, read and write operations on the AT24C02. To read and write eeprom in order to facilitate observation of the results, we will read and write data simultaneously displayed in the seven-segment digital tube, and set read and write data from 0 to 255 in cycles, so that can be easily compared.)
