The following excerpt shows how to map the decinal counter output to ASCII charcters for the LCD display.

parameter LINE1 = 5;
parameter LUT_SIZE = LINE1+5;

always
begin
    case(LUT_INDEX)
    0:    LUT_DATA    <=    9'h038;
    1:    LUT_DATA    <=    9'h00C;
    2:    LUT_DATA    <=    9'h001;
    3:    LUT_DATA    <=    9'h006;
    4:    LUT_DATA    <=    9'h080;
    //    Line 1
    LINE1+0:    LUT_DATA    <=    9'h120;    // blanks    
    LINE1+1:    LUT_DATA    <=    9'h120;
    LINE1+2:    LUT_DATA    <=    {5'h13,digit3};
    LINE1+3:    LUT_DATA    <=    {5'h13,digit2};
    LINE1+4:    LUT_DATA    <=    {5'h13,digit1};
    LINE1+5:    LUT_DATA    <=    {5'h13,digit0};
    default:        
        LUT_DATA    <=    9'dx ;
    endcase
end

The LCD display state machine is restarted once per second, corresponding to the timer update rate.
