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
