uc/os3多任务与实时日历
- 一、STM32F103C8T6移植uCOS
- 二、简单多任务实现
- 三、RTC实时时钟
- 四、逻辑分析仪使用
一、STM32F103C8T6移植uCOS
1.uCOS下载
STM32F107uCOS样例下载
下载完成后文件如下：
2.文件导入
1）项目创建
使用STM32CUBEMX创建空项目
2）项目管理
1、在新建项目中新建文件夹UCOSIII
2、将官网样例文件中的uC-CPU、uC-LIB、uCOS-III移动到新建的文件夹UCOSIII中，并新建文件夹uCOS-BSP、uCOS-CONFIG文件
3,文件添加
新建Groups：uCOS-BSP、uCOS-CPU、uCOS-LIB、uCOS-Core、uCOS-Port、uCOS-Config
1、uCOS-BSP中添加文件
2、uCOS-CPU中添加文件
3、uCOS-LIB中添加文件
4、uCOS-Core中添加文件
5、uCOS-Port中添加文件
6、uCOS-Config中添加文件
4,头文件路径添加
3.文件修改
改
DCD PendSV_Handler ; PendSV Handler
DCD SysTick_Handler ; SysTick Handler
为
改
PendSV_Handler PROC
EXPORT PendSV_Handler [WEAK]
B .
ENDP
SysTick_Handler PROC
EXPORT SysTick_Handler [WEAK]
B .
ENDP
为
2、app_cfg.h
改
#define APP_CFG_SERIAL_EN DEF_ENABLED
为
#define APP_CFG_SERIAL_EN DEF_DISABLED
改
#define APP_TRACE BSP_Ser_Printf
为
#define APP_TRACE (void)
3、includes.h
第一处修改：
添加相关头文件
#include <bsp.h>
修改为
#include <bsp.h>
#include “gpio.h”
#include “app_cfg.h”
#include "app.h"
第二处修改：
添加HAL 库
#include <stm32f10x_lib.h>
修改为
#include "stm32f1xx_hal.h"
4、 bsp.c和bsp.h
//bsp.c
#include "includes.h"
#define DWT_CR *(CPU_REG32 *)0xE0001000
#define DWT_CYCCNT *(CPU_REG32 *)0xE0001004

#if(OS_VERSION>=3000u)

#else

#endif
OS_CPU_SysTickInit(cnts);
}
void BSP_Init(void)
{

}
#if (CPU_CFG_TS_TMR_EN == DEF_ENABLED)
void CPU_TS_TmrInit (void)
{

DWT_CYCCNT = (CPU_INT32U)0u;

cpu_clk_freq_hz = BSP_CPU_ClkFreq();
CPU_TS_TmrFreqSet(cpu_clk_freq_hz);
}
#endif
#if (CPU_CFG_TS_TMR_EN == DEF_ENABLED)

{

}
#endif
#if (CPU_CFG_TS_32_EN == DEF_ENABLED)

return (ts_us);
}
#endif
###################################################################
//bsp.h
#ifndef __BSP_H__
#define __BSP_H__
#include "stm32f1xx_hal.h"
void BSP_Init(void);
#endif /* End of module include.
5、lib_cfg.h
这个头文件中有一个宏定义：
#define LIB_MEM_CFG_HEAP_SIZE 27u * 1024u
表示把堆的空间设置为27KB，但是我使用的stm32f103c8t6的RAM总共才20K，所以这里需要将堆空间改小一点，我改成了10K
#define LIB_MEM_CFG_HEAP_SIZE 10u * 1024u
此处的修改若是对于RAM空间较大的单片机是没有必要的，但是对于小容量的单片机则是必须的。

结果
三、RTC实时时钟
工作过程
STM32CubeMx实现日历
1.项目创建
1）新建STM32CubeMx项目
时钟树设置
RCC设置
RTC设置
串口设置
2.日期打印代码
定义结构体
/* USER CODE BEGIN PV */
RTC_DateTypeDef GetData; //获取日期结构体
RTC_TimeTypeDef GetTime; //获取时间结构体
/* USER CODE END PV */
重写串口输出
int fputc(int ch,FILE *f){
uint8_t temp[1]={ch};
HAL_UART_Transmit(&huart1,temp,1,2);
return ch;
}
串口打印时间
while (1)
{
/* Get the RTC current Time */
HAL_RTC_GetTime(&hrtc, &GetTime, RTC_FORMAT_BIN);
/* Get the RTC current Date */
HAL_RTC_GetDate(&hrtc, &GetData, RTC_FORMAT_BIN);
/* Display date Format : yy年mm月dd日 */
printf("%02d年%02d月%02d日",2000 + GetData.Year, GetData.Month, GetData.Date);
/* Display time Format : hh时mm分ss秒 */
printf("%02d时%02d分%02d秒\r\n",GetTime.Hours, GetTime.Minutes, GetTime.Seconds);
a=GetData.WeekDay;
if(a==01){printf("星期一\r\n");}
else if(a==02){printf("星期二\r\n");}
else if(a==03){printf("星期三\r\n");}
else if(a==04){printf("星期四\r\n");}
else if(a==05){printf("星期五\r\n");}
else if(a==06){printf("星期六\r\n");}
else if(a==07){printf("星期天\r\n");}
HAL_Delay(1000);
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
}

四、逻辑分析仪使用
一、GPIO逻辑分析
1.多任务逻辑分析
如图为uCOS多任务移植的GPIO高低电平输出逻辑图
一个周期为灯a闪3下，灯b闪1下
二、串口逻辑分析
RTC时间串口输出分析
串口输出为：
