一、在STM32CubeMX中建立工程
- 配置RCC
- 配置SYS
- 配置PC13为GPIO_Output
- 配置USART1
- 生成代码
二、获取uC/OS-III源码
官网下载地址:Micrium Software and Documentation - Silicon Labs
网盘下载:百度网盘 请输入提取码
提取码:lzjl
三、复制uC/OS-III到工程文件夹
- 在生成的keil工程文件夹中新建一个UCOSIII的文件夹,将我们下载的源代码中四个文件夹:uC-CPU、uC-LIB、ucoS CONFIG、uCOS-II复制到我们新建的文件夹中:
- 在工程文件夹中的Src文件夹下新建一个OS文件夹。
- 将刚才下载源码打开,将uCOS-III下的文件:app.c 、 app_cfg.h 、 cpu_cfg.h 、 includes.h 、 lib_cfg.h 、 os_app_hooks.c 、os_app_hook.h、os_cfg.h、os_cfg_app.h复制到上一步建立的OS文件夹中,同时新建三个空白文件: bsp.c、bsp.h、app.h
四、添加工程组件和头文件路径
(一)添加工程分组
打开STM32CubeMX创建的工程, 按照如图所示添加六个新的组:bsp、 uCOSIII CPU、
uCOSIII_ LIB、uCOSIII_ Ports、uCOSIII_ Source、OS_cfg。
(二)添加文件到分组
1、文件目录是: Src/OS,将其中 bsp.c 和 bsp.h文件添加至 bsp 组中,将 app.c 添加进 Application/User 组中
2、uCOSIII_CPU组件, 点击Add Files…按钮,将文件目录跳转至:UCOSIII/uC-CPU,选择 ALL files文件类型,将其中的三个文件点击 Add 添加, 然后再打开: ARM-Cortex-M3\RealView, 同样选择 ALL files 文件类型,将三个文件添加进uCOSIII_CPU组。
3、同理来添加 uCOSIII_LIB 组件文件:选择 uCOSIII_LIB 组,点击 Add Files…按钮, 将文件目录跳转至: UCOSIII/uCLIB,选择 ALL files 文件类型,将其中的九个文件添加进 uCOSIII_LIB 组;然后继续打开: Ports/ARM-Cortex-M3/Realview, 添加 lib_mem_a.asm 文件
4、添加选择 uCOSIII_Ports 组,点击 Add Files…按钮, 将文件目录调整至: UCOSIII/UcosIII/Ports/RAM-Cortex-M4/Generic/RealView。选择 ALL files 文件类型, 将其中三个文件添加进 uCOSIII_Ports 组。
5、选择uCOSIII_Sourc组,点击Add Files…按钮, 将文件目录调整至: UCOSIII/UcosIII/Source。选择 ALL files 文件类型, 将其中二十个文件添加进 uCOSIII_Sourc 组。
6、选择 OS_cfg 组,点击 Add Files…按钮, 将文件目录调整至: Src/OS。选择 ALLfiles 文件类型, 将图中的八个文件添加进 uCOSIII_Sourc 组
至此所有工程组件都添加完毕。
(三)添加头文件路径
将下图所框的地址加入其中:
至此头文件路径也添加完毕。
五、修改文件的内容
(一)启动文件
(二)app_cfg.h文件
- 第一处修改:
修改前:
#define APP_CFG_SERIAL_EN DEF_ENABLED
修改后:
#define APP_CFG_SERIAL_EN DEF_DISABLED
- 第二处修改:
修改前:
#define APP_TRACE BSP_Ser_Printf
修改后:
#define APP_TRACE (void)
(三)includes.h
- 第一处修改:添加相关的头文件
修改前:
#include <bsp.h>
修改后:
#include <bsp.h>
#include "gpio.h"
#include "app_cfg.h"
#include "app.h"
- 第二处修改:添加HAL库
修改前:
#include <stm32f10x_lib.h>
修改后:
#include "stm32f1xx_hal.h"
(四)bsp.c和bsp.h
bsp的.c和.h文件直接复制如下代码即可:
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)

{

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)
{

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
bsp.h:
// bsp.h
#ifndef __BSP_H__
#define __BSP_H__
#include "stm32f1xx_hal.h"
void BSP_Init(void);
#endif
(五)app.c和app.h
app.c我们实际是用main.c代替,所以app.c中没有什么实际的代码,这里将其保留,也可选择删除,注意头文件包含即可。
#include <includes.h>
// app.h
#ifndef __APP_H__
#define __APP_H__
