EDA16x16点阵滚动+动画显示范本模板
四、课程设计的总体步骤
1、单个字符的显示（如：
黄）：
libraryieee;
useieee。
std_logic_1164。
all;
useieee。
std_logic_unsigned。
all;
entityxianshiis
port（clk2:
instd_logic;
rck,sck：
outstd_logic；
si：
outstd_logic）;
end;
architectureoneofxianshiis
signalsel：
std_logic_vector（3downto0）；
signalq:
std_logic_vector（31downto0）;
signali：
integerrange0to31;
signalcoi：
std_logic；
begin
process（sel,clk1）
begin
caseselis
when”0000”=>q<="00000100000000000111111111111111”；
when”0001”=>q<=”00000100000000011011111111111111";
when”0010”=〉q<="00100100000000011101111111111111";
when”0011"=>q<="00100101111110101110111111111111”;
when"0100"=>q〈=”00100101010100101111011111111111";
when”0101”=〉q〈=”11111101010101001111101111111111”;
when”0110”=>q<="00100101010100001111110111111111"；
when"0111"=>q〈=”00100111111100001111111011111111”;
when"1000"=〉q〈="00100101010100001111111101111111";
when”1001”=>q〈="11111101010101001111111110111111";
when"1010”=>q〈="00100101010101001111111111011111”；
when”1011"=>q〈="01100111111100101111111111101111”;
when"1100”=〉q<=”00100100100000101111111111110111"；
when"1101"=>q<=”00001100000000011111111111111011";
when”1110"=>q〈=”00000100000000001111111111111101”;
when”1111”=〉q<="00000000000000001111111111111110”;
whenothers=〉null；
endcase;
ifclk1'eventandclk1=’1’then
si<=q（i）;i<=i+1；coi<=’0’;
ifi=31theni〈=0；coi<='1'；sel<=sel+'1';
endif;
rck<=notcoi；
endif；
endprocess；
sck〈=clk1；
end;
时序仿真：
从图中可以看出，当clk1在第32个上升沿rck变为低电频，sck与clk1是同一电频，故此程序满足要求。
