基于 STM32CubeMX 添加 RT-Thread 操作系统组件(七)- 线程管理

概述 

       本篇只要介绍这么使用STM32CubeMx工具添加RT-Thread操作系统组件,码代码的IDE是keil。介绍单线程SRAM静态内存使用。如果还不知道,这么使用STM32CubeMx工具添加RT-Thread操作系统组件,请移步到《基于 STM32CubeMX 添加 RT-Thread 操作系统组件(一)- 详细介绍操作步骤》文章阅读。好了,喝杯茶先^_^,继续前行。上一篇介绍关于《RT-Thread 的启动流程》

 

一、STM32CubeMx配置

二、KEIL IDE

  1. 在Application/User文件夹,新建app_rt_thread.c文件,并添加如下代码:
    #include "rtthread.h"
    #include "main.h"
    #include "stdio.h"
    
    
    /* 定义线程控制块 */
    static rt_thread_t led1_thread = RT_NULL;
    static rt_thread_t key_thread = RT_NULL;
    
    static void led1_thread_entry(void* parameter);
    static void key_thread_entry(void* parameter);
    
    
    int MX_RT_Thread_Init(void)
    {
    	rt_kprintf("This is an RTT thread management experiment! \n");
    	rt_kprintf("Press K1 to suspend the thread, and Press K2 to restore the thread! \n"); 
    	led1_thread = /* 线程控制块指针 */
    	rt_thread_create( "led1", /* 线程名字 */
    				led1_thread_entry, /* 线程入口函数 */
    				RT_NULL, /* 线程入口函数参数 */
    				512, /* 线程栈大小 */
    				4, /* 线程的优先级 */
    				20); /* 线程时间片 */
    	/* 启动线程,开启调度 */
    	if (led1_thread != RT_NULL)
    		rt_thread_startup(led1_thread);
    	else
    		return -1;
    	
    	key_thread = /* 线程控制块指针 */
    	rt_thread_create( "key", /* 线程名字 */
    				key_thread_entry, /* 线程入口函数 */
    				RT_NULL, /* 线程入口函数参数 */
    				512, /* 线程栈大小 */
    				3, /* 线程的优先级 */
    				20); /* 线程时间片 */
    	/* 启动线程,开启调度 */
    	if (key_thread != RT_NULL)
    		rt_thread_startup(key_thread);
    	else
    		return -1;
    }
    
    
    /*
    *************************************************************************
    * 线程定义
    *************************************************************************
    */
    static void led1_thread_entry(void* parameter)
    {
    	while (1) {
    		HAL_GPIO_WritePin(LED1_GPIO_Port, LED1_Pin, GPIO_PIN_SET);
    		rt_thread_delay(500); /* 延时 500 个 tick */
    		rt_kprintf("led1_thread running,LED1_ON\r\n");
    		HAL_GPIO_WritePin(LED1_GPIO_Port, LED1_Pin, GPIO_PIN_RESET);
    		rt_thread_delay(500); /* 延时 500 个 tick */
    		rt_kprintf("led1_thread running,LED1_OFF\r\n");
    	}
    }
    static void key_thread_entry(void* parameter)
    {
    	rt_err_t uwRet = RT_EOK;
    	while (1) {/* K1 被按下 */ 
    		if ( HAL_GPIO_ReadPin(KEY1_GPIO_Port,KEY1_Pin) == GPIO_PIN_SET ) { 
    			rt_kprintf("Suspend LED1 thread!\n");
    			uwRet = rt_thread_suspend(led1_thread);/* 挂起 LED1 线程 */
    			if (RT_EOK == uwRet) {
    				rt_kprintf("LED1 thread suspended successfully!\n");
    			} else {
    				rt_kprintf("Suspended LED1 thread failed! Failed code: 0x%lx\n",uwRet);
    			}
    		}/* K2 被按下 */
    		if ( HAL_GPIO_ReadPin(KEY2_GPIO_Port,KEY2_Pin) == GPIO_PIN_SET ) {
    			rt_kprintf("Restore LED1 thread!\n");
    			uwRet = rt_thread_resume(led1_thread);/* 恢复 LED1 线程! */
    			if (RT_EOK == uwRet) {
    				rt_kprintf("Restore LED1 thread successfully!\n");
    			} else {
    				rt_kprintf("Restore LED1 thread failed! Failed code: 0x%lx\n",uwRet);
    			}
    		}
    		rt_thread_delay(20);
    	}
    }
    

     

  2. 在main.c文件添加如下代码:
    /* USER CODE END Header */
    
    /* Includes ------------------------------------------------------------------*/
    #include "main.h"
    #include "usart.h"
    #include "gpio.h"
    
    /* Private includes ----------------------------------------------------------*/
    /* USER CODE BEGIN Includes */
    
    /* USER CODE END Includes */
    
    /* Private typedef -----------------------------------------------------------*/
    /* USER CODE BEGIN PTD */
    extern int MX_RT_Thread_Init(void);
    /* USER CODE END PTD */
    
    /* Private define ------------------------------------------------------------*/
    /* USER CODE BEGIN PD */
    /* USER CODE END PD */
    
    /* Private macro -------------------------------------------------------------*/
    /* USER CODE BEGIN PM */
    
    /* USER CODE END PM */
    
    /* Private variables ---------------------------------------------------------*/
    
    /* USER CODE BEGIN PV */
    
    /* USER CODE END PV */
    
    /* Private function prototypes -----------------------------------------------*/
    void SystemClock_Config(void);
    /* USER CODE BEGIN PFP */
    
    /* USER CODE END PFP */
    
    /* Private user code ---------------------------------------------------------*/
    /* USER CODE BEGIN 0 */
    
    /* USER CODE END 0 */
    
    /**
      * @brief  The application entry point.
      * @retval int
      */
    int main(void)
    {
      /* USER CODE BEGIN 1 */
    
      /* USER CODE END 1 */
    
      /* MCU Configuration--------------------------------------------------------*/
    
      /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
      HAL_Init();
    
      /* USER CODE BEGIN Init */
    
      /* USER CODE END Init */
    
      /* Configure the system clock */
      SystemClock_Config();
    
      /* USER CODE BEGIN SysInit */
    
      /* USER CODE END SysInit */
    
      /* Initialize all configured peripherals */
      MX_GPIO_Init();
      MX_USART1_UART_Init();
      /* USER CODE BEGIN 2 */
      MX_RT_Thread_Init();
      /* USER CODE END 2 */
    
      /* Infinite loop */
      /* USER CODE BEGIN WHILE */
      while (1)
      {
        /* USER CODE END WHILE */
    
        /* USER CODE BEGIN 3 */
      }
      /* USER CODE END 3 */
    }

     

  3. 自定义rt_hw_console_output()函数,在kservice.c文件添加中(重映射串口控制台到 rt_kprintf 函数)代码:
    #include "usart.h"
    .
    .
    .
    
    RT_WEAK void rt_hw_console_output(const char *str)
    {
        /* empty console output */
    	/* 进入临界段 */
    	rt_enter_critical();
    	/* 直到字符串结束 */
    	while (*str!='\0') {
    	/* 换行 */
    	if (*str=='\n') {
    		HAL_UART_Transmit(&huart1,(uint8_t *)'\r',1,1000);
    	}
    		HAL_UART_Transmit(&huart1,(uint8_t *)(str++),1,1000);
    	}
    	/* 退出临界段 */
    	rt_exit_critical();
    }

  4. 运行结果
