ok,, in my code when compile, generate multiple output pins, not a single pin "deci" why?
library ieee;
use ieee.std_logic_1164.all;
use ieee.numeric_std.all;
entity joystick is
port
(
d1,d2,d3,d4,d5,d6,d7,d8 : in std_logic;
deci : out integer range 0 to 255) ;
end joystick;
architecture lectura of joystick is
signal val_bin : std_logic_vector(7 downto 0);
begin
val_bin <= d8 & d7 & d6 & d5 & d4 & d3 & d2 & d1;
deci <= to_integer(signed(val_bin));
end lectura;
i can save this output in one only value for send these after data to a serial COM for using in a program in PC? my code generate various output pins.
