文件为用C#编写的串口调试助手，基本的功能已经实现，本人自测是正常的，提供源码可以再次基础上做出更好的上位机。-File for the preparation of C# serial debugging assistant, the basic function has been achieved, I self-test is normal, to provide the source code can be made on the basis of better software.

这是用C#编写的 串口调试助手,免费共享源代码,enjoy yourself!(This is written in c # serial debugging assistant, free sharing source code, enjoy yourself!)

串口通讯助手，包含C#源程序。每条语句含有注释。(Serial communication assistant, including the C# source program. Each statement contains annotations.)

main.c已详尽注释连接的引脚 和 调试助手参数。STM32分别以串口,硬件SPI,模拟并口驱动CH395,4个socket连接, 原路返回上位机发送的数据。串口模式支持更改工作波特率，硬件SPI速率最高36MHz, 模拟并口较快，这三种模式支持在stm32任意型号下。(Main.c has commented on pins and debugging assistant parameters in detail. STM32 drives CH395 and 4 sockets by se
