RT-Thread Nano是RT-Thread的精简版,只有内核、shell(msh)、设备驱动三大功能,以Keil5的pack形式发布。RT-Thread Nano在保证了具备完整功能的RTOS实时内核的前提下实现了极小的FLASH和RAM占用,默认配置下,FLASH可小至2.5KB, RAM可以小至1KB,对于当今主流32位MCU/SoC来说,跑起来毫无压力。

下面就跟随小编一起,看看如何在机智云gokit智能硬件开发板上将RT-Thread Nano跑起来吧~

一、RT-Thread Nano Pack安装

1.  使用STM32CubeMX创建一个可以点亮板载LED的基本工程,参考:http://club.gizwits.com/thread-3859-1-1.html
2.  在MDK5主界面上点击“Pack Install”按钮,进入Pack Install界面:


3.  在Pack Install界面下,RT-Thread Pack在右边栏中。点击“Install”可下载,点击“Update”可更新。


4.  如果在上图界面“Packs”栏中未发现“RT-Thread”,通过两种方法获取RT-Thread Pack。
第一种方法是直接从http://www.rt-thread.org/downloa ... rtthread.2.1.1.pack下载2.1.1版本的的RT-Thread Pack,然后双击完成安装。
第二种方法是在菜单“Packs”下点击“Check for Updates”,Update完成后,将可看到RT-Thread Pack,然后下载Pack再安装它。


二、kernel加载与应用


1.  在主界面点击“ManageRun-TimeEnvironment”进入加载页:


在“RTOS”一栏中选中“RT-Thread”,并在列表中选中“kernel”:


2.  确定后,RT-Thread的kernel文件会被自动添加进来:



Kernel文件包括:
clock.c
components.c
device.c
idle.c
ipc.c
irq.c
kservice.c
mem.c
object.c
scheduler.c
thread.c
timer.c
Cortex-M芯片内核移植代码:
cpuport.c
context_rvds.s
应用代码及配置文件:
board.c
rtconfig.h

三、修改源码适配机智云Gokit


1.需要做一些微小的修改才能在Gokit上跑起来:
1)修改Application/User分组下的stm32f1xx_it.c文件,删除如下3个函数:
  • void HardFault_Handler(void);
  • void PendSV_Handler(void);
  • void SysTick_Handler(void);

[color=rgb(0, 0, 0) !important]复制代码

2)修改RTOS分组下的board.c上文件:
修改第24行为:
  • #include "stm32f1xx_hal.h"

[color=rgb(0, 0, 0) !important]复制代码

修改第66行:取消注释,并加入2行代码如下。
  • void SysTick_Handler(void)
  • {
  •         /* enter interrupt */
  •         rt_interrupt_enter();
  • <font color="#ff00ff">        HAL_IncTick();
  •         HAL_SYSTICK_IRQHandler();</font>
  •         rt_tick_increase();
  •         /* leave interrupt */
  •         rt_interrupt_leave();
  • }

[color=rgb(0, 0, 0) !important]复制代码

3)在rtconfig.h使能动态内存管理:


此外,第15行,修改RT_TICK_PER_SECOND为1000。

2.  修改main.c文件,屏蔽掉while(1)死循环,加入测试代码:

测试代码使用RT-Thread的动态线程创建函数rt_thread_create()创建了2个线程,在线程里面间隔不同的时间翻转LED。
