一、概述

APM32F411VET6的USART3，UART4，UART5在XX32F411VET6是没有的，保留了相应的地址空间。在APM32F411VET6中这部分地址空间被用作了USART3，UART4，UART5。在使用XX32f411的XX32CubeMX开发时，没有相关的外设配置选项，我们可以自己改HAL库，以支持USART3，UART4，UART5。

二、修改

修改启动文件startup_xx32f411xe.s
中断向量表

默认中断处理

添加USART3的时钟使能，失能，基地址等定义
定义声明基地址

定义时钟操作

中断号定义

GPIO端口复用定义

中断服务函数

三、测试代码

四、展示

五、心得与体会

APM32F411VET6的UART兼容XX32F411VET6，目前完成了发送和中断接收。测试下来还是可以的，有喜欢CubeMX开发的朋友可以看一下。如有错误请大佬勿喷。需要例程的私聊我，附件太大。
