How to write the verilog code for fpga to recieve input from the computer keyboard through RS-232
Is this right?
module serialfun(clk, RxD, TxD, GPout, GPin);
input clk;
input RxD;
output TxD;
output [7:0] GPout;
input [7:0] GPin;
///////////////////////////////////////////////////
wire RxD_data_ready; wire [7:0] RxD_data;
async_receiver deserializer(.clk(clk), .RxD(RxD), .RxD_data_ready(RxD_data_ready), .RxD_data(RxD_data));
reg [7:0] GPout;
always @(posedge clk) if(RxD_data_ready) GPout <= RxD_data;
///////////////////////////////////////////////////
async_transmitter serializer(.clk(clk), .TxD(TxD), .TxD_start(RxD_data_ready), .TxD_data(GPin));
