Hi all,

Finally, we decided to make something as simple as possible, and to compensate with the power of the NIOS II.

Is it possible to use only export signals? The data from my sensor would go into a register.

Then in the NIOS IDE, I would read registers (registre_ecriture) thanks to IORD.

How can I know the addresses of my registers?

read : in std_logic; --avalon

architecture a of juste_le_slave is

signal registre_ecriture : std_logic_vector(7 downto 0);

signal registre_controle : std_logic_vector(7 downto 0);

begin

process(pclk)

begin

if(pclk&#39;event AND pclk=&#39;1&#39; AND read=&#39;1&#39;) then

if (href=&#39;1&#39;) then

if (registre_controle="00000000") then

registre_controle<="11111111";

end if;

registre_ecriture<=data;

else if(vsyn=&#39;1&#39;) then

registre_controle<="00000000";

end if;

end if;

end if;
