I av used 89v51rd2 microcontroller, a decoder to select one row at a time, 8 shift register to which data is serially bitwise sent. The shift reg controls the scrolling display for 8 (5*7)led matrix [7 rows,5 cols, anode=row,cathode=col]. Now I am breaking my head on developing the code to control scrolling display. Can nebody explain me wrt to 1 character suppose 'A' wat codes to send to decoder and shift reg to display it scrolling.
