| How to file in a Eeprom |

I am trying to log the date on a EEPROM, but my code doesn't want to work. Please help me for some reason my rs232 communication doesn't want to work either.
Thanks in advance

| Code: | logtoEE(i , i);
readEE (i , i); |
The second parameter is wrong in both calls. |

Try the changes below (not tested)
| Code: | void main()
{
int8 RecordNr; // Moved the variable declarations out of the loop.
// And I like int8 better as it is easier to port to other compilers.
struct lvlData currentEntry; // removed the '*' because you do not want a pointer but have to reserve memory.
setup(); // moved out of loop for optimization.
while(1)
{
RecordNr = 0;
printf( " \n Die datum " );
// delay_ms(50); no delay required here
levelData.dd = 1; // Day
levelData.mt = 2; // Month
levelData.hh = 3; // Hour
levelData.mm = 4; // Minute;
levelData.ss = 5;
levelData.lev= 6;
logtoEE(RecordNr, &levelData); // A '&' indicates the compiler we want to pass the address of the struct
readEE (RecordNr, ¤tEntry);
// Because we changed the declaration of currentEntry, we had to change the data access below from '->' to '.'
printf( "\nDag %d", currentEntry.dd); // Day
printf( "\nMaand %d", currentEntry.mt); // Month
printf( "\nUur %d", currentEntry.hh); // Hour
printf( "\nMinuut %d", currentEntry.mm); // Minute
printf( "\nSeconde %d", currentEntry.ss); // Second
}

Thanx very much for the help, i understand a lot better now, still i get this errors
--- Info 300 "P:\main1.c" Line 83(2,9): More info: First Declaration of lvlData
*** Error 31 "P:\main1.c" Line 175(18,25): Identifier is already used in this scope
it has something to do with
| Code: |
struct lvldata currentEntry
|
when i change it to
| Code: |
struct lvldata *currentEntry
|
it works but returns the wrong values.
Sorry to bother |

'levelData' declaration is missing:
| Code: | struct lvlData currentEntry;
struct lvlData levelData; |

My mistake (I said I didn't test it) 
Forget the well intended suggestion from SET. In my posted main(), change | Code: | | struct lvlData currentEntry; |
to | Code: | | lvlData currentEntry; |

Oops, I didnt see levelData declared further up, I only looked at the snippet in 'main'  |

So now i have both
| Code: |
lvlData levelData
lvlData currentEntry
|
No error anymore - Thank you very much!
But the only value that is returned is -1
Any futher ideas would be greatly apreciated
Thank for all the help up to here! |

What is your compiler version?
Where do you see the -1 values? |

when i printf dd,hh,mt,ss etc.
My compiler version is V4.033
dd = -1
hh = -1
etc |

Sorry i wasn't logged in.
| Code: |
printf( " \nDag %d" , currentEntry->dd); // Day
printf( " \nMaand %d" , currentEntry->mt); // Month
printf( " \nUur%d" , currentEntry->hh); // Hour
printf( " \nMinute%d" , currentEntry->mm); // Minute
printf( " \nSekondes%d" ,currentEntry->ss); // Second
delay_ms(500);
|
The values being displayed here returns -1 values |
