    Too many parameters left unstated. What flavor of 8051 are you using? What is the specific problem you are having trouble with?

    IT CAN USE TIME CONTROLER... SOMETHING LIKE BELOW, BUT I DON'T KNOW HOW TO REPLACE THE BY USING FOR EXAMPLE PO.O OR P1.0... ORG 0H
    SJMP 30H
    ORG 0BH
    SJMP ISR
    ORG 30H
    MOV A,#00
    MOV R0,#0
    MOV R1,#0
    MOV TMOD,#02H
    MOV TH0,#118
    MOV IE,#82H
    SETB TCON.4
    HERE:
    SJMP HERE
    ISR:
    CLR TCON.4
    INC R1
    CJNE R1,#100,SKIP
    MOV R0,#00H
    INC A
    SKIP:
    SETB TCON.4
    RETI
    END
    ALSO DON'T KNOW IF THIS CAN BE IMPLEMENTED TO BCD 7SEGx4... THANKS
