imemkeycode = imemkeycode + eeprom_read(addr++);

If data in eeprom is 1234. 12 is stored at address 0x0001 and 34 is stored at address 0x0000. First you retrieve value at address 0x0001 and multiply it with 100 and you get 1200. Then you get the value 34 and add it to 1200 and get 1234. The above code is wrong. It is my mistake. First read addr++ and then read addr.

method to write to eeprom.

1234

1234/100 = 12
1234%100 = 34

12 = 0Ch
34 = 22h

0x0000 = 22h
0x0001 = 0Ch
