机智云Gokit开发板RT-Thread Nano快速创建工程

z3512641347

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： /**   ****************************************************   * File Name          : main.c   * Description        : Main program body   ****************************************************   ** This notice applies to any and all portions of this file   * that are not between comment pairs USER CODE BEGIN and   * USER CODE END.
