EEPROM, STM8S, TE, Remote, ni

初始化部分，这个部分可以成功的写入，和读出来

void EEPROM_Init(void)
{
  //unlock EEPROM
  FLASH->DUKR = 0xAE;
  FLASH->DUKR = 0x56;
  EEP_Wait_Finished();
  if ((eeprom_variable[0]=='T') && (eeprom_variable[1]=='G') && (eeprom_variable[2]==8) && (eeprom_variable[3]==0x00))
  {
Remote_ID[0] = E2_ReadMem(0);
Remote_ID[1] = E2_ReadMem(1);
Remote_ID[2] = E2_ReadMem(2);
Remote_ID[3] = E2_ReadMem(3);
  }
  else
  {
Remote_ID[0] = 0xaa; //第一次
Remote_ID[1] = 0xaa;
Remote_ID[2] = 0xaa;
Remote_ID[3] = 0xaa;
E2_WriteBurst(0, 4, Remote_ID);

E2_ResetEEPROM();
  }
  EEP_Wait_Finished();
}

void E2_ResetEEPROM(void)
{
  EEP_Wait_Finished();
  eeprom_variable[0] = 'T'; //"TG80" is written  in the EEPROM
  EEP_Wait_Finished();
  eeprom_variable[1] = 'G'; //This allows to check later that the EEPROM content is valid.
  EEP_Wait_Finished();
  eeprom_variable[2] = 8;
  EEP_Wait_Finished();
  eeprom_variable[3] = 0x00;
  EEP_Wait_Finished();
}

在这个部分，写入ID时就是写不进去。奇怪？
if(Save_ID_标志寄存器 == 1 && RX_buf[4] == 15) //学习模式，保存ID
   {
      Save_ID_标志寄存器 = 0;
      Remote_ID[0] = RX_buf[0]; // ID
      Remote_ID[1] = RX_buf[1];
      Remote_ID[2] = RX_buf[2];
      Remote_ID[3] = RX_buf[3];
      //E2_WriteBurst(0, 4, Remote_ID);


      EEP_Wait_Finished();
      eeprom_variable[4] = Remote_ID[0]; //"TG80" is written  in the EEPROM
      EEP_Wait_Finished();
  eeprom_variable[5] = Remote_ID[1]; //This allows to check later that the EEPROM content is valid.
  EEP_Wait_Finished();
  eeprom_variable[6] = Remote_ID[2];
  EEP_Wait_Finished();
  eeprom_variable[7] = Remote_ID[3];
  EEP_Wait_Finished();

   }
