Up/down counter Quartus II UP2 board

before to show my vhdl code i thanks you for reply me :))))

this is my work until now:

library ieee;

use ieee.std_logic_1164.all;

use ieee.std_logic_unsigned.all;

ENTITY counter IS

PORT(

clk : in BIT;

upordwn : in STD_LOGIC;

initial : in STD_LOGIC_VECTOR(7 DOWNTO 0);

count : OUT STD_LOGIC_VECTOR(7 DOWNTO 0);

LED_1 : OUT STD_LOGIC_VECTOR(7 DOWNTO 0);

LED_2 : OUT STD_LOGIC_VECTOR(7 DOWNTO 0);

LED_CENT : OUT STD_LOGIC_VECTOR(7 DOWNTO 0));

end counter;

ARCHITECTURE prova OF counter IS

SIGNAL totalbit : STD_LOGIC_VECTOR(7 DOWNTO 0);

SIGNAL up_four : STD_LOGIC_VECTOR(4 DOWNTO 0);

SIGNAL low_four : STD_LOGIC_VECTOR(4 DOWNTO 0);

BEGIN

PROCESS(clk)

--QUI DEVO INSERIRE IL VALORE INIZIALE

if(clk'EVENT AND clk='1') THEN

if (upordwn='1') THEN

totalbit <= totalbit+1;

else

totalbit <= totalbit-1;

end if;

end if;

END PROCESS;

low_four(0) <= totalbit(0);

low_four(1) <= totalbit(1);

low_four(2) <= totalbit(2);

low_four(3) <= totalbit(3);

up_four(0) <= totalbit(4);

up_four(1) <= totalbit(5);

up_four(2) <= totalbit(6);

up_four(3) <= totalbit(7);

WITH up_four SELECT

--abcdefg

LED_1 <= "00000011" WHEN "1111", -- 0

"01100001" WHEN "0001", -- E

"01110001" WHEN "0000", -- F

"00000011" WHEN OTHERS;

count <= totalbit;

end prova;

I have two problems yet!

1. initialing a strart number for the count by 8 switches present in UP2 board;

2. show the result in decimal (not in hexadecimal format) in the 7segment display.

thanks again :D
