C语言以结构体的方式写入eeprom数据

unsigned char   min_change0=0,  //要保存的变量值第一组，每一次改变都会保存
unsigned char   min_change_backup0=0; //该变量为中间变量，用于与min_change做对比，下同

unsigned char   min_change1=0,  //要保存的变量值第二组，每一次改变都会保存
unsigned char   min_change_backup1=0;

unsigned char   min_change2=0,  //要保存的变量值第三组，每一次改变都会保存  
unsigned char   min_change_backup2=0;

void EEPROM_Write(timeset*, unsigned char, unsigned char) ; //数据保存并写入EEPROM
EEPROM_write(unsigned char,  unsigned char, );  //内部EEPROM写入函数


typedef struct  EEPROM_Save
{
        unsigned char* min_set;
        unsigned char* min_set_backup;
} timeset;


timeset  EEPROM_SAVE[3] ={      //定义并初始化一个结构体数组，数组元素是指针，数组元素为三组需要保存的数据
{&min_change0, &min_change_backup0},
{&min_change1, &min_change_backup1},
{&min_change2, &min_change_backup2}

};

int main(void)
{
   while(1)
   {
      for(int j=0; j <3; j++)
      {
         EEPROM_Write(EEPROM_SAVE,  j,  (j+1)) ;
      }
   }
}


void EEPROM_Write(timeset* table, unsigned char i, unsigned char addr)
{
        if (*(table[i].min_set)  != *(table[i].min_set_backup)) //如果min_change和min_change_backup不相等，则开始保存
        {
              *(table[i].min_set_backup) = *(table[i].min_set) ; //保存数据
                  EEPROM_write(addr,  *(table[i].min_set_backup));  //写入EEPROM

         }
