EEPROM dump setup


In order to catch data losses, the data is stored redundantly.



CRC function:

unsigned char dump[0x1000];
...

unsigned short getCheckSum(unsigned short dumpStartIndex,
                           unsigned short dumpEndIndex,
                           unsigned short blockNumber)
{
  unsigned short checksum = 0;
  for (unsigned int i = dumpStartIndex; i <= dumpEndIndex; i++)
  {
    checksum = checksum + dump[i];
  }

  checksum = 0xFFFF ^ checksum;
  checksum = checksum - blockNumber;

  return checksum;
}



OMI function:

unsigned int getOmi_1(void)
{
  return dump[0x156];
}

unsigned char getOmi_2(void)
{
  return dump[0x176];
}
...

//omi On  -> omiByte = 0x73;
//omi Off -> omiByte = 0x60;
void setOmi_1(unsigned char omiByte)
{
  dump[0x156] = omiByte;
  unsigned short checksum = getCheckSum(0x140, 0x15D, 4);
  dump[0x15E] = checksum & 0xFF;
  dump[0x15F] = checksum >> 8;
}

void setOmi_2(unsigned char omiByte)
{
  dump[0x176] = omiByte;
  unsigned short checksum = getCheckSum(0x160, 0x17D, 4);
  dump[0x17E] = checksum & 0xFF;
  dump[0x17F] = checksum >> 8;
}



WFS-Code:

unsigned short getWFSLogin_1(void)
{
  return dump[0xE7] * 0x100 + dump[0xE8];
}

unsigned short getWFSLogin_2(void)
{
  return dump[0x107] * 0x100 + dump[0x108];
}

unsigned short getWFSLogin_3(void)
{
  return dump[0x127] * 0x100 + dump[0x128];
}



Mileage of engine control unit:

unsigned long getKM_1(void)
{
  return dump[0x502]  * 0x1000000  +  dump[0x503]  * 0x10000  +  dump[0x504]  * 0x100  +   dump[0x505]; //unit meter
}

unsigned long getKM_2(void)
{
  return dump[0x542]  * 0x1000000  +  dump[0x543]  * 0x10000  +  dump[0x544]  * 0x100  +   dump[0x545]; //unit meter
}
