串口与电脑的通信 可以用调试助手 进行试验 采用verilog语言设计 编译已通过-Serial communication with the computer test can be used with debugging assistant compiled verilog language design has passed

使用PS2的键盘，向键盘输入字符，通过串口通讯，把字符显示到电脑上（过程需要使用到串口调试助手）-Using the PS2 keyboard to keyboard input characters via the serial port, the characters are displayed on the computer (process requires using the serial debugging assistant)

在STM32板子与电脑串口助手进行通信,用串口的DMA方式,先接收,再发送到PC端,可以连续接收,通过按键一次发送.(In the STM32 board and computer serial assistant for communication, using the serial port DMA way, first receive, and then sent to the PC terminal, you can receive continuously, sent through
