RS:out STD_LOGIC;
RW:out STD_LOGIC;
EN:out STD_LOGIC;
a:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
b:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
c:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
d:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
e:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
f:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
wa:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
wb:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
wc:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
da:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
db:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
ma:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
mb:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
ya:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
yb:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
yc:OUT STD_LOGIC_VECTOR(7 DOWNTO 0);
yd:OUT STD_LOGIC_VECTOR(7 DOWNTO 0));
process()
begin
RS<='0';
RW<='0';
EN<='1';
a<=qa;b<=qb;c<=qc;d<=qd;e<=qe;f<=qf;wa<=week1;wb<=week2;wc<=week3;da<=day1;db<=day2;ma<=month1;mb<=month2;ya<=year1;yb<=year2;yc<=year3;yd<=year4;
year1234是年的四个数字month12是月的两个数字,以此类推,abcdef是时分秒,我用vhdl语言写的是这样的,可要怎样在液晶显示屏上显示出来呢
求求各位大哥大姐
