器计时器,你能教我怎样写吗?
当然可以!下面是一个例子,你可以参考一下:
```
module led_and_display(
input clk,
output [7:0] AN,
output reg [6:0] SEG,
output reg LED
);
reg [23:0] count;
always @(posedge clk) begin
count <= count + 1;
if (count == 24000000) begin
LED <= ~LED;
count <= 0;
end
end
always @(posedge clk) begin
case (count[19:17])
0: SEG <= 7'b100_0000;
1: SEG <= 7'b111_1001;
2: SEG <= 7'b010_0100;
3: SEG <= 7'b011_0000;
4: SEG <= 7'b001_1001;
5: SEG <= 7'b001_0010;
6: SEG <= 7'b000_0010;
7: SEG <= 7'b111_1000;
8: SEG <= 7'b000_0000;
9: SEG <= 7'b001_0000;
default: SEG <= 7'b111_1111;
endcase
case (count[23:20])
0: AN <= 8'b1111_1110;
1: AN <= 8'b1111_1101;
2: AN <= 8'b1111_1011;
3: AN <= 8'b1111_0111;
4: AN <= 8'b1110_1111;
5: AN <= 8'b1101_1111;
6: AN <= 8'b1011_1111;
7: AN <= 8'b0111_1111;
default: AN <= 8'b1111_1111;
endcase
end
endmodule
```
这段代码实现了一个简单的数字计时器,每秒钟LED灯会闪烁一次,同时七段数码管会不断显示增加的时间。不过该代码并未完整实现所需要的功能,你可以根据需要进行修改和完善。
