Saving RFID Data

Hi Skimask,
What you mean with out of bond!?
Did you mean when I receive a wrong character.
Regards Pesti

What happens if you get a character that you weren't expecting? One with a value too low or too high...

For instance:
Daten[N]= ((Daten[N]-$30) *10) + (Daten[N-1]-$30)

What happens if the value in 'Daten[N]' or 'Daten[N-1] is $30? is $20? is $0?
