基于arm的u盘实验，优盘虚拟读写实验的源代码-Based on experimental arm of the u disk, USB virtual experiments the source code to read and write

1、STM32F103ZET6虚拟串口实验-1, STM32F103ZET6 virtual serial experiments

这是一款改编自Keil例程的虚拟串口的程序，利用端点2和端点3实验USB转虚拟串口的功能，收发数据。-This is a program adapted a virtual serial port Keil routines, the serial port function using the experimental endpoint 2 and 3 USB to virtual endpoints, send and receive data.
