[Help] ad677 driver for fpga

I'm using an FPGA and already use an AD699 which works great.

Now I'm trying to drive an AD677 but I have a problem when I want to read the result because I don't have the same (nearly) results each time I want a sample.


Here the part of code to get a sample


mesure : process(Sclk, init, Sdata, Busy)

variable i : integer :=16;

variable data_out_temp : std_logic_vector(15 downto 0);



if (rising_edge(Sclk) and init>=86000) then  -- init is only to read after calibration



    Data_out_temp(i):=Sdata ;


        if i=0 then



        end if;


    end if;

end if;


If you have some answer ... Thanks
