说明：  对IIC开发非常有启发性的一个程序，像24C02，1024/1025这些IIC总线的存储器的读写都是很有用，看此程序就可以大概知道如何连续读写多个字节
(The development of the IIC a very instructive process, such as 24C02, 1024/1025 The IIC bus memory read and write are very useful to see if this program could probably know how to read and write more bytes of consecutive)
