STM32之移植uCOSIII（HAL库）

一.使用CubeMX建立STM32F103C8T6HAL库

配置sys

设置PC13为GPIO_Output用于点亮LED灯

设置串口USART1

设置工程

在main函数中的while循环里添加语句

while (1)
  {
   
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
		HAL_GPIO_WritePin(GPIOC, GPIO_PIN_13, GPIO_PIN_SET);
		HAL_Delay(500);
		HAL_GPIO_WritePin(GPIOC, GPIO_PIN_13, GPIO_PIN_RESET);
		HAL_Delay(500);
  }
  /* USER CODE END 3 */
  

二.准备uCOSIII源码

进入官网下载：http://micrium.com/downloadcenter/

或链接：https://pan.baidu.com/s/10RqsDRecbmVteWmDv2oUNQ

1.为uC-BSP文件夹新建bsp.c和bsp.h文件
2.给文件夹uC-CONFIG添加以下文件

3.将uCOS相关文件复制到HAL工程的MDK-ARM文件夹下

三.开始移植

1.将uCOS文件添加到项目
点击Manage Project Items
为项目新建文件夹如下
点击CPU–>Add Files…，选中以下文件，Add

点击CPU–>Add Files…，选中以下文件，Add

点击LIB–>Add Files…，选中以下文件，Add

点击PORT–>Add Files…，选中以下文件，Add

点击CONFIG–>Add Files…，选中以下文件，Add

点击BSP–>Add Files…，选中以下文件，Add

此时项目结构会发生变化

导入文件路径

从项目路径下寻找

2.为bsp.c和bsp.h添加代码
添加代码如下：
bsp.h

// bsp.h
#ifndef  __BSP_H__
#define  __BSP_H__

#include "stm32f1xx_hal.h"

void BSP_Init(void);

#endif

bsp.c

// bsp.c
#include "includes.h"

#define  DWT_CR      *(CPU_REG32 *)0xE0001000
#define  DWT_CYCCNT  *(CPU_REG32 *)0xE0001004
#define  DEM_CR      *(CPU_REG32 *)0xE000EDFC
#define  DBGMCU_CR   *(CPU_REG32 *)0xE0042004

#define  DEM_CR_TRCENA                   (1 << 24)
#define  DWT_CR_CYCCNTENA                (1 <<  0)

CPU_INT32U  BSP_CPU_ClkFreq (void)
{
   
    return HAL_RCC_GetHCLKFreq();
}

void BSP_Tick_Init(void)
{
   
	CPU_INT32U cpu_clk_freq;
	CPU_INT32U cnts;
	cpu_clk_freq = BSP_CPU_ClkFreq();
	
	#if(OS_VERSION>=3000u)
		cnts = cpu_clk_freq/(CPU_INT32U)OSCfg_TickRate_Hz;
	#else
		cnts = cpu_clk_freq/(CPU_INT32U)OS_TICKS_PER_SEC;
	#endif
	OS_CPU_SysTickInit(cnts);
}



void BSP_Init(void)
{
   
	BSP_Tick_Init();
	MX_GPIO_Init();
}


#if (CPU_CFG_TS_TMR_EN == DEF_ENABLED)
void  CPU_TS_TmrInit (void)
{
   
    CPU_INT32U  cpu_clk_freq_hz;


    DEM_CR         |= (CPU_INT32U)DEM_CR_TRCENA;                /* Enable Cortex-M3's DWT CYCCNT reg.                   */
    DWT_CYCCNT      = (CPU_INT32U)0u;
    DWT_CR         |= (CPU_INT32U)DWT_CR_CYCCNTENA;

    cpu_clk_freq_hz = BSP_CPU_ClkFreq();
    CPU_TS_TmrFreqSet(cpu_clk_freq_hz);
}
#endif


#if (CPU_CFG_TS_TMR_EN == DEF_ENABLED)
CPU_TS_TMR  CPU_TS_TmrRd (void)
{
   
    return ((CPU_TS_TMR)DWT_CYCCNT);
}
#endif


#if (CPU_CFG_TS_32_EN == DEF_ENABLED)
CPU_INT64U  CPU_TS32_to_uSec (CPU_TS32  ts_cnts)
{
   
	CPU_INT64U  ts_us;
  CPU_INT64U  fclk_freq;

 
  fclk_freq = BSP_CPU_ClkFreq();
  ts_us     = ts_cnts / (fclk_freq / DEF_TIME_NBR_uS_PER_SEC);

  return (ts_us);
}
#endif
 
 
#if (CPU_CFG_TS_64_EN == DEF_ENABLED)
CPU_INT64U  CPU_TS64_to_uSec (CPU_TS64  ts_cnts)
{
   
	CPU_INT64U  ts_us;
	CPU_INT64U  fclk_freq;


  fclk_freq = BSP_CPU_ClkFreq();
  ts_us     = ts_cnts / (fclk_freq / DEF_TIME_NBR_uS_PER_SEC);
	
  return (ts_us);
}
#endif

3.修改main.c文件代码

#include "main.h"
#include "gpio.h"
#include "usart.h"
/* Private includes ----------------------------------------------------------*/

/* 任务堆栈大小	*/
#define START_STK_SIZE 		64
#define LED0_STK_SIZE 		64
#define MSG_STK_SIZE 		64//任务堆大小过大会报错，可以试着改小一点

/* 任务栈 */	
CPU_STK START_TASK_STK[START_STK_SIZE];

/* 任务控制块 */
OS_TCB StartTaskTCB;

/* USER CODE END PD */

/* Private macro -------------------------------------------------------------*/
/* USER CODE BEGIN PM */
