[嵌入式]基于STM32F767IGT6的RT-thread工程

RT-thread版本：4.0.1，几乎是最新版

为了能让像我一样喜欢白嫖的小伙伴能不求人借会员就可以下载到资源，我把代码的百度云链接放在文章末尾，小伙伴们可以用百度云下载。

代码使用的是串口6作为二号串口，可能有些代码是显示串口2或者3的，那是我懒得改了，忽略即可。整个工程使用设备驱动的方式调用串口6，将串口6接收到的数据从串口1输出。串口6配置函数我写在USART.c中，如果后续想要使用其他串口的话在USART.c中参照USART6_Config();的样子写一个函数就好了。

PS：由于F767的官方例程并没有串口6的相关配置，所以我是自己添加的，串口中断优先级是占用了串口5的优先级，使用串口5的话需要注意一下

keil工程文件位于RT-thread_v4.0.1\rt-thread\bsp\stm32\stm32f767-atk-apollo中，不想重复打开的话可以创建一个快捷方式
