RS232 Communication function in VHDL for Spartan 3E

基于spartan3e的串口驱动程序，使用verilog编写-Based spartan3e serial driver, written using the verilog

用xilinx的FPGA-spartan3E实现uart，固定波特率9600，偶校验，系统时钟50MHz，能够实现将从串口调试助手发送到FPGA的数据重新发回串口调试助手-using xilinx s FPGA-spartan3E to implement uart with a baudrate of 9600, even parity check. The system frequency is 50MHz.It can turn the data from serial assistant
