RTT Studio和Cubemx联合开发

1. RTT studio创建工程

创建工程

## 创建完成以后的目录结构

2. 配置CubuMx

双击cubumx的图标打开CubeMx
配置时钟

生成代码

构建后的代码结构

编译代码满屏错误：不要慌

3. 新增脚本

新建scons脚本文件 SConscript

脚本内容如下，每次修改外设后度需要增加外设c文件的添加，本次使用了gpio.c 和 usart.c文件

import os
from building import *

cwd = GetCurrentDir()
src  = Glob('*.c')
# add cubemx drivers
src = Split('''
Src/stm32f4xx_hal_msp.c
Src/main.c
Src/gpio.c
Src/usart.c
''')
print(src)
path = [cwd]
path += [cwd + '/Inc']

group = DefineGroup('cubemx', src, depend = [''], CPPPATH = path)

Return('group')

执行脚本，回报错就是存在2个main函数入口

开始编译代码，如果编译后还是很多错误，那就再执行一次脚本

修改main函数为弱函数，执行编译结果如下图

修改 application 目录下main.c文件，使用2个现场 点亮 2个LED

7. 编译
   

8. 下载
   
   配置调试终端
   
   执行命令
