一、使用STM32CubeMX生成工程
1. 打开软件
2. 基于芯片创建工程
3. 选择对应芯片
- 此处我是采用的stm32f429igt6
4. 设置GPIO
5. 设置串口
6. 设置时钟为180MHz
- 此处选用内部时钟，如需外部时钟请自定义配置
7. 工程设置
8. 生成工程，编译运行，验证
二、TencentOS tiny文件移植
1. 获取源码
2. 下载到本地，解压如图所示
3. 复制源码文件到mdk工程目录
- 打开STM32CubeMX生成的工程目录，添加
TencentOS tiny文件夹，将步骤二的三个文件夹复制到此文件夹
4.新增配置目录及文件
- 其中，头文件内容如下，注意修改引入的头文件名称：
#ifndef _TOS_CONFIG_H_
#define _TOS_CONFIG_H_
#include "stm32f4xx_hal.h" // 目标芯片头文件，用户需要根据情况更改
#define TOS_CFG_TASK_PRIO_MAX 10u // 配置TencentOS tiny默认支持的最大优先级数量
#define TOS_CFG_ROUND_ROBIN_EN 0u // 配置TencentOS tiny的内核是否开启时间片轮转
#define TOS_CFG_OBJECT_VERIFY_EN 1u // 配置TencentOS tiny是否校验指针合法
#define TOS_CFG_TASK_DYNAMIC_CREATE_EN 1u // TencentOS tiny 动态任务创建功能宏
#define TOS_CFG_EVENT_EN 1u // TencentOS tiny 事件模块功能宏
#define TOS_CFG_MMBLK_EN 1u //配置TencentOS tiny是否开启内存块管理模块
#define TOS_CFG_MMHEAP_EN 1u //配置TencentOS tiny是否开启动态内存模块
#define TOS_CFG_MMHEAP_DEFAULT_POOL_EN 1u // TencentOS tiny 默认动态内存池功能宏
#define TOS_CFG_MMHEAP_DEFAULT_POOL_SIZE 0x100 // 配置TencentOS tiny默认动态内存池大小
#define TOS_CFG_MUTEX_EN 1u // 配置TencentOS tiny是否开启互斥锁模块
#define TOS_CFG_MESSAGE_QUEUE_EN 1u // 配置TencentOS tiny是否开启消息队列模块
#define TOS_CFG_MAIL_QUEUE_EN 1u // 配置TencentOS tiny是否开启消息邮箱模块
#define TOS_CFG_PRIORITY_MESSAGE_QUEUE_EN 1u // 配置TencentOS tiny是否开启优先级消息队列模块
#define TOS_CFG_PRIORITY_MAIL_QUEUE_EN 1u // 配置TencentOS tiny是否开启优先级消息邮箱模块
#define TOS_CFG_TIMER_EN 1u // 配置TencentOS tiny是否开启软件定时器模块
#define TOS_CFG_PWR_MGR_EN 0u // 配置TencentOS tiny是否开启外设电源管理模块
#define TOS_CFG_TICKLESS_EN 0u // 配置Tickless 低功耗模块开关
#define TOS_CFG_SEM_EN 1u // 配置TencentOS tiny是否开启信号量模块
#define TOS_CFG_TASK_STACK_DRAUGHT_DEPTH_DETACT_EN 1u // 配置TencentOS tiny是否开启任务栈深度检测
#define TOS_CFG_FAULT_BACKTRACE_EN 0u // 配置TencentOS tiny是否开启异常栈回溯功能
#define TOS_CFG_IDLE_TASK_STK_SIZE 128u // 配置TencentOS tiny空闲任务栈大小
#define TOS_CFG_CPU_TICK_PER_SECOND 1000u // 配置TencentOS tiny的tick频率
#define TOS_CFG_CPU_CLOCK (SystemCoreClock) // 配置TencentOS tiny CPU频率
#define TOS_CFG_TIMER_AS_PROC 1u // 配置是否将TIMER配置成函数模式
#endif
三、MDK工程分组目录及头文件设置
1. 添加分组目录
tos/archtos/kerneltos/cmsis_ostos/config
2. 添加tos/arch分组文件
3. 添加tos/kernel分组文件
4. 添加tos/cmsis_os分组文件
5. 添加tos/config分组文件
6. 添加头文件路径
- 按下图新增头文件路径
四、MDK源码修改，创建TencentOS tiny任务
1. 修改stm32f4xx_it.c中断配置文件
- 添加以下代码
/* USER CODE BEGIN Includes */
#include "tos_k.h"
/* USER CODE END Includes */
- 修改
PendSV_Handler函数
__weak void PendSV_Handler(void)
{
/* USER CODE BEGIN PendSV_IRQn 0 */
/* USER CODE END PendSV_IRQn 0 */
/* USER CODE BEGIN PendSV_IRQn 1 */
/* USER CODE END PendSV_IRQn 1 */
}
- 修改
SysTick_Handler函数
void SysTick_Handler(void)
{
/* USER CODE BEGIN SysTick_IRQn 0 */
/* USER CODE END SysTick_IRQn 0 */
HAL_IncTick();
/* USER CODE BEGIN SysTick_IRQn 1 */
if (tos_knl_is_running())
{
tos_knl_irq_enter();
tos_tick_handler();
tos_knl_irq_leave();
}
/* USER CODE END SysTick_IRQn 1 */
}
2. 在main.c函数中新建任务
main.c源码如下
/* USER CODE BEGIN Header */

3. 观察现象
- task1和task2交替运行
