STM32的I2C-EEPROM已调试成功

万利的I2C-EEPROM例程有些问题，经本人两个昼夜的反复试验，已修改完善。

修改了两个地方，在void I2C_EE_BufferWrite(u8* pBuffer, u8 WriteAddr, u16 NumByteToWrite)写操作函数和void I2C_EE_BufferRead(u8* pBuffer, u8 ReadAddr, u16 NumByteToRead)读操作函数体内的开头先要执行一句I2C_EE_WaitEepromStandbyState();

这样在以后调用写操作函数和读操作函数时就不用执行I2C_EE_WaitEepromStandbyState()了。但上电复位后先要执行一次读操作，以后就可以无限制的随便调用这两个函数了。

详细如下。
