基于verilog语言的，FPGA程序实现电脑与FPGA串口的数字传输，硬件设备为EP1C3T100C8，usb转RS232芯片为FT232BM，-Based verilog language, FPGA program FPGA serial digital transmission of computer and hardware devices to EP1C3T100C8, usb to RS232 chip FT232BM,

收发端都采用2M波特率发送串口数据，通过PIN口直接输入输出串口数据，目的是为了跟外围高速器件完成高速的串口数据的收发，普通USB转串口的都只能支持不到1M的波特率，内部采用乒乓FIFO进行时钟域切换以及缓存(The transmitter and receiver are used 2M baud rate serial data transmission, directly through the PIN port serial input and output data, the purp
