作业LED灯1秒闪烁

源代码：


module ledflicker(sys_clk,
                  sys_rstn,
      LED
      );
input sys_clk;
input sys_rstn;
output[7:0]LED;
reg[7:0]LED;
reg[25:0]delay_cnt;

always@(posedge sys_clk or negedge sys_rstn)
      begin
      if(!sys_rstn)

         if(delay_cnt==26'd49999999)
          delay_cnt<=26'd0;
       else

教程实现的功能我就不上传了，教程发有完整的工程文件

作业LCD12864中文显示
我的是带字库的，将文字转换为十六进制来显示的。
转换用的软件：ASCII


关键代码：
always @(posedge clkr)
begin
 current=next;
  case(current)
    set0:   begin  rs<=0; dat<=8'h31; next<=set1; end 
    set1:   begin  rs<=0; dat<=8'h0C; next<=set2; end

作业LCD12864显示其他图片

主要代码：

调用rom的部分：
wire [7:0] showdata;
rom rom (.address (cnt),
   .clock (sys_clk),
   .q (showdata)
   );

 
endmodule

VGA显示彩条

通过拨段开关7、8可以实现棋盘四种模式：横条、竖条、棋盘格A、棋盘格B的显示


关键代码：
//vga行、场扫描
parameter hsync_end   = 10'd95,
   hdat_begin  = 10'd143,
   hdat_end  = 10'd783,
   hpixel_end  = 10'd799,
   vsync_end  = 10'd1,
   vdat_begin  = 10'd34,
   vdat_end  = 10'd514,
   vline_end  = 10'd524;
