Hi there , can anyone give me some tips , hints or examples about this topic. I am sure anything will be a great help.
I made a program with a few displays where are one or two keypad entry variable . I just want to scroll between the displays to see the values of variables ( this I all ready made with keypad force entry) and when I want to modify the values of variables a password entry will appear. In this case the variables will be protect against changes made by unauthorized persons .
Best regards.
