storing strings in eeprom

[tkidder]

I have a barcode reader application that gets ascii data , up to 20 characters
that are all numeric, "0012345678905" for example. I need to store these codes in internal eeprom memory, 18f452. The only way i know is to split the barcode into two strings, then convert to long integers,
x=atoi32(string1);
y=atoi32(string2);
//then save

WRITE_LongEEPROM(20,string1);

WRITE_LongEEPROM(30,string2);

To retrieve the data I need to convert each part back
and reassamble them into the origional string.
One of the problems is that the atoi32 function strips the leading zeros.

any help would be greatly appreciated.

You could save it as packed BCD (two digits per byte), and also save a
byte the tells how many digits are in the number.

How many of these 20-digit numbers do you need to save ?

Depending on the amount of data that you need to store and the size of eeprom you could simply store the original ascii data to the eeprom. The number 0(zero) would be stored as 0x30, 9 would be 0x39 and so forth. This way you could take what you get from the serial port and go right to the eeprom without any need for conversions.

I am using, get_string(barcode); to get the data from the scanner.
into char code[20];
are there any examples of how to store this string in eeprom? I assume i would need to store each character in consecutive byte locations.Would i need to convert to hex? I would then need to retrieve the bytes and assemble into a string. There should be no problem with storage since only one code is being saved.
Sorry for my ignorance on this subject.
