# Console串口使用说明
RT-Thread工程中默认Console使用的串口为Uart1。在实际使用过程中串口1不一定适合作为Console调试口。本文介绍如何将Console口更改到其他串口上面。
## UART外设驱动添加
打开“\dist\project\board\CubeMX_Config”目录下CubeMx工程文件
使能对应的UART并打开中断，并生成代码

**注意要将CubeMx生成的系统时钟初始化函数，copy到board.c里面**
## 修改Kconfig文件
打开 board 文件夹下的 Konfig 文件，拷贝 UART1 的配置项，并重命名UART1为 UART3。

menuconfig配置使能UART3
