好的,以下是一个简单的Verilog代码实现双灯左移右移和闪烁的流水灯程序。
```verilog
module LED_flow(
input clk,
output reg [7:0] LED
);
reg [2:0] state;
reg [23:0] count;
always @(posedge clk) begin
count <= count + 1;
case(state)
3'b000: begin
if(count >= 2000000) begin
LED <= 8'b00000001;
state <= 3'b001;
count <= 0;
end
end
3'b001: begin
if(count >= 2000000) begin
LED <= 8'b00000010;
state <= 3'b010;
count <= 0;
end
end
3'b010: begin
if(count >= 2000000) begin
LED <= 8'b00000100;
state <= 3'b011;
count <= 0;
end
end
3'b011: begin
if(count >= 2000000) begin
LED <= 8'b00001000;
state <= 3'b100;
count <= 0;
end
end
3'b100: begin
if(count >= 2000000) begin
LED <= 8'b00010000;
state <= 3'b101;
count <= 0;
end
end
3'b101: begin
if(count >= 2000000) begin
LED <= 8'b00100000;
state <= 3'b110;
count <= 0;
end
end
3'b110: begin
if(count >= 2000000) begin
LED <= 8'b01000000;
state <= 3'b111;
count <= 0;
end
end
3'b111: begin
if(count >= 2000000) begin
LED <= 8'b10000000;
state <= 3'b000;
count <= 0;
end
end
endcase
end
always @(posedge clk) begin
if(count >= 1000000) begin
LED <= ~LED;
count <= 0;
end
end
endmodule
```
这个模块使用了一个状态机来控制流水灯的不同模式,同时也使用了一个简单的计数器来控制流水灯的速度。其中,LED输出位向左移动,右移动和闪烁的模式是通过在状态机中不同的状态来实现的。同时,一个简单的闪烁效果也在代码中实现了。
