Honored ContributorHi 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? <div class='quotetop'>QUOTE </div> --- Quote Start --- LIBRARY ieee; USE ieee.std_logic_1164.ALL; USE ieee.numeric_std.ALL; entity juste_le_slave is port ( --entrées externes data : in std_logic_vector(7 downto 0); --export, data from the sensor vsyn : in std_logic; --export pclk : in std_logic; --export href : in std_logic; --export read : in std_logic; --avalon readdata : out std_logic_vector(7 downto 0) --avalon ); end; 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'event AND pclk='1' AND read='1') then if (href='1') then if (registre_controle="00000000") then registre_controle<="11111111"; end if; registre_ecriture<=data; else if(vsyn='1') then registre_controle<="00000000"; end if; end if; end if; if (registre_controle="0000000") then readdata<=registre_controle; else readdata<=registre_ecriture; end if; end process; end a;[/b] --- Quote End ---
