RT-Thread 14. GD32F330RBT6 Keil4移植RT-Thread

1.增加rt-thread-v4.1.0源码

在这里插入图片描述

rt-thread-v4.1.0\bsp\gd32350r-eval复制重命名为gd32f330_v1

2.文件组织结构

Usr：存放App任务应用，属于应用层，完全脱离硬件
CMSIS：硬件层，启动文件、系统文件
Driver：硬件外设驱动库（MCU厂商提供）
rt-thread_components_board：bsp\gd32f330_v1\drivers文件夹，板级BSP
rt-thread_src：\src文件夹，rt-thread内核源码
rt-thread_libcpu：\libcpu文件夹，rt-thread内核源码
rt-thread_components_finsh：components\finsh文件夹
rt-thread_components_driver：components\drivers文件夹

插一句，\bsp\gd32\libraries\gd32_drivers不适合用于GD32F330芯片

在这里插入图片描述

宏定义，–c99，头文件路径

3.menuconfig

保存之后自动更新rtconfig.h

在这里插入图片描述

4.代码

主要修改Usr（App）、rt-thread_bsp_board（BSP）文件，但rtconfig.h使用ENV菜单方式menuconfig命令修改后保存自动得到。
在这里插入图片描述
