我想根据不同的时钟显示段，但我不能

Question

棒形状固定在片段的左侧，点片段要根据时钟单独显示。 但与此同时，它显示了这是一个示例图片https://imgur.com/LXGVUJO

    library ieee;

为你的第二个过程尝试类似的东西

signal digit_display : std_logic := '0';

process(clk)       
begin

    if rising_edge(clk) then

      digit_display <= not(digit_display);

      if digit_display = '1' then

        dot_seg <= '0';

        if player_clk = '1' then        -- player 
          case player_in is                       
            when "00" => seg <= "1000110";
            when "01" => seg <= "1000011";
            when "10" => seg <= "0010101";
            when "11" => seg <= "1000110";
            select_seg <= "01111111";
          end case;
        end if;

      else

        seg <= "0000000"; -- Full off, I don't know polarity

        if dot_clk = '1' then       -- dot(road) segment
          dot_seg <= '1';
          select_seg <= "01011111";
        else
          dot_seg <='1';
          select_seg <= "10101111";
        end if;

      end if;

    end if;

end process;

如果clk太快而无法使用digit_display闪烁，你可以像这样放一个计数器：

signal digit_display_count : unsigned(15 downto 0) := (others => '0');

if digit_display_count = 100 then -- Choose an appropriate value
  digit_display       <= not(digit_display);
  digit_display_count <= (others => '0')
else
  digit_display_count <= digit_display_count + 1;
end if;
