internal problem related to 8051

design a microcontroller 8051 based display control system to display numbers..from 0 to 9999d.four segment display modules are common cathode type.draw the circuit diagram with multiplexer to indicate how single port can be used to connect four modules.use port p1 to connect 7 segment display.only draw the flow chart for logical program implementation.....plz give me some solution to this problem....

Did you notice that there are more forums than RF, Microwave, Antennas and Optics? A correct title would be "Help me with 8051 programm" or someting like this.
