24LC256 wrong address at reading

[falingtrea]

Hello all,
I wonder if someone can help me with this problem.

I'm storing manualy some values to 24LC256 with an external programmer and editor like this :

:020000040000FA                                                ' THis line was from a blank memory - not changed
:10000000 48 45 4C 4C 4F 21 FF FF 4B 4D 31 37 57 53 FF 00  'This is the line I edit with my values
>         0  1  2  3  4  5  6  7  8  9  A  B  C  D  E  F
:10001000 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF  F0    'All zeros
>         0  1  2  3  4  5  6  7  8  9  A  B  C  D  E  F  cksum
:10002000 FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFE0    'All zeros
...........continues.......
:107FF000FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF91    'Last line at address 7FF0
:00000001FF                                                        ' THis line was from a blank memory - not changed

Looks like you are one byte short on the line you edited. Each line should be 16 bytes plus a checksum. What also looks odd is that the address jumps by
0x1000 (4k) per line and not 0x10 (16).

Most good programmers have an editor built in. You would be better off using the editor to change the data and then save it off in a hex format instead of trying to edit the hex file. That way the per line check sum would be correct.
