_primary.vhd

可以在里面修改协议.主要是cmos---fpga--usb(68013a)中除68013a部分的程序

library verilog;
use verilog.vl_types.all;
entity fpga_fpga_1280x8_tb is
    generic(
        SENDFILE01      : string  := "uart_send_data1.dat";
        idle            : integer := 1;
        start           : integer := 17;
        write           : integer := 2;
        W_and_R         : integer := 4;
        write_c         : integer := 8;
        clear           : integer := 0;
        clear_start     : integer := 9
    );
end fpga_fpga_1280x8_tb;
