小弟帮你
1、车速控制模块源程序如下：
LIBRARY IEEE;
USE IEEE.STD_LOGIC_1164.ALL;
USE IEEE.STD_LOGIC_UNSIGNED.ALL;
ENTITY SPEED IS
PORT(
CLK,RESET,START:IN STD_LOGIC;
K :IN STD_LOGIC_VECTOR(4 DOWNTO 0);
CLKOUT :OUT STD_LOGIC
);
END SPEED;
ARCHITECTURE A OF SPEED IS
SIGNAL COUNT1 :STD_LOGIC_VECTOR(1 DOWNTO 0);
SIGNAL TEMPCLK,CLKS:STD_LOGIC;
SIGNAL KINSIDE :STD_LOGIC_VECTOR(4 DOWNTO 0);
BEGIN
KINSIDE
