Thank you very much for the help. However, I have another problem. If I write to an eeprom address over 255 (8 bits) it writes to the target address and also to the target address minus 256. For example if I write to 256 it will write the data to address 256 and address 0. Any solutions for this? Is there a format for writing the address over 256? I\'m using WriteByte from the example programs on a MinMax51c with a T89C51RD2 and serial eeprom.
WriteByte( deviceNumber, address, data )
UBYTE deviceNumber;
unsigned address;
UBYTE data;
{
ERRCODE ec;
unsigned temp;
ec = Start();
if( ec != SUCCESS )
return ec;
ec = Transmit( I2C_DEVICE_24CXX | I2C_WRITE | (deviceNumber << 1) );
if( ec != SUCCESS )
goto func_end;
ec = Transmit( address & 0xFF );
if( ec != SUCCESS )
goto func_end;
ec = Transmit( data );
printf("\\nWriteByte=%d",data);
if( ec != SUCCESS )
goto func_end;
func_end:
Stop();
return ec;
}
