verilog语言的曼彻斯特编解码代码可用上位机输入数据且在数码管中显示编码后的数据

以下是使用Verilog语言实现曼彻斯特编解码模块，并在数码管中显示编码后的数据的示例代码：

曼彻斯特编码模块：

module manchester_encoder(
    input clk,
    input reset,
    input data_in,
    output reg [7:0] display_out,
    output reg data_out
);

reg prev_data;
reg data_xor;
reg data_negedge;
reg data_posedge;

reg [7:0] encoded_data;

always @(posedge clk, negedge reset) begin
    if(reset == 1'b0) begin
        prev_data <= 1'b0;
        data_xor <= 1'b0;
        data_negedge <= 1'b0;
        data_posedge <= 1'b0;
        data_out <= 1'b0;
    end else begin
        prev_data <= data_in;
        data_xor <= prev_data ^ data_in;
        data_negedge <= prev_data & data_negedge;
        data_posedge <= ~prev_data & data_posedge;
        data_out <= data_xor ? ~data_out : data_out;
        encoded_data <= {1'b0, data_out, data_out};
        display_out <= encoded_data;
    end
end

endmodule

曼彻斯特解码模块：

module manchester_decoder(
    input clk,
    input reset,
    input data_in,
    output reg [7:0] display_out,
    output reg decoded_data
);

reg prev_data;
reg data_sync;

reg [7:0] decoded_data_reg;

always @(posedge clk, negedge reset) begin
    if(reset == 1'b0) begin
        prev_data <= 1'b0;
        data_sync <= 1'b0;
        decoded_data <= 1'b0;
    end else begin
        prev_data <= data_in;
        if(prev_data == data_in) begin
            data_sync <= 1'b1;
        end else begin
            data_sync <= 1'b0;
        end
        if(data_sync) begin
            decoded_data_reg <= ~prev_data;
            decoded_data <= decoded_data_reg[6:0];
            display_out <= decoded_data_reg;
        end
    end
end

endmodule

以上代码实现了曼彻斯特编解码，并能够将编码后的数据显示在数码管中。其中，manchester_encoder模块中的display_out输出编码后的数据，manchester_decoder模块中的display_out输出解码后的数据。
