stm32F103-RT-Thread移植(固件库版本)-项目创建

创建一个固件库项目 参考:野火固件库创建 >下载RT-Thread

>安装RT-Thread >https://www.keil.com/dd2/pack/ >

移植开始

• 将packs文件夹中的RealThread复制到刚创建的固件库项目中

复制

#### 粘贴 粘贴到项目文件夹后然后根据项目进行移植 其他文件夹都可以删除
> 管理的头文件

>#### RTT内核代码移植 >#### 芯片文件

> # 整理完项目结构

多层目录添加–> 直接输入rtt/ports

> ### 添加环境变量

修改rtconfig.h

该头文件对裁剪整个 RT-Thread 所需的功能的宏均做了定义，有些宏定义被使能，有些宏定义被失能，一开始我们只需要配置最简单的功能即可。要想随心所欲的配置 RT- Thread 的功能，我们必须对这些宏定义的功能有所掌握，下面我们先简单的介绍下这些宏定义的含义，然后再对这些宏定义进行修改。(摘自野火RTT)

• 代码清单: 移植 RTT-1 (1) ：头文件 RTE_Components.h 是在 MDK 中添加 RT-Thead Package
时由 MDK 自动生成的，目前我们没有使用 MDK 中自带的 RT-Thread 的 Package，所以这
个头文件不存在，如果包含了该头文件，编译的时候会报错，等下修改 rtconfig.h 的时候需
要注释掉该头文件。


[ 修改4处如下 ]

//#include "RTE_Components.h"
#define RT_THREAD_PRIORITY_MAX  8
#define RT_TICK_PER_SECOND 1000
#define RT_MAIN_THREAD_STACK_SIZE     512

修改 board.c

在user下创建board.h

PendSV_Handler,HardFault_Handler…重复定义错误 > 屏蔽即可, 推荐直接将stm32f10x_it.h和stm32f10x_it.c清空,如下!!!!
