说明： STM32F103 USB转双串口。使用CDC类。插上电脑后，会出来两个虚拟串口，如果提示找不到驱动，指定驱动路径到inf文件夹即可。
相比ST官方提供的只有1路串口的例程，方便了很多
用到的IO定义如下：
串口1：PA9和PA10
const GPIO_InitTypeDef TX1_pin { GPIO_Pin_9, GPIO_Speed_50MHz, GPIO_Mode_AF_PP }
const GPIO_InitTypeDef RX1_pin { GPIO_Pin_10, GPIO_Speed_50MHz, GPIO_Mode_IN_FLOATING }
串口2：PA2和PA3
const GPIO_InitTypeDef TX2_pin { GPIO_Pin_2, GPIO_Speed_50MHz, GPIO_Mode_AF_PP }
const GPIO_InitTypeDef RX2_pin { GPIO_Pin_3, GPIO_Speed_50MHz, GPIO_Mode_IN_FLOATING }
USB使能脚：PC15
#define USB_DISCONNECT GPIOC
#define USB_DISCONNECT_PIN GPIO_Pin_15 //GPIO_Pin_12
#define RCC_APB2Periph_GPIO_DISCONNECT RCC_APB2Periph_GPIOC
你可以根据自己板子的定义自行修改，修改办法是搜索上面这些宏定义，找到地方直接改掉并重新编译即可
