msg display
My display uses 7x5 matrix character so I used 5 codes for each char. these codes are hard programmed in the programm mem at the time of programming the micro.
so fix message to scroll each time. But now I want keyboard /PC interface to change the message when the user wish to. need to redesign the f/w and h/w.
Suggest some suitable program logic...
