一、使用CubeMX建立HAL库
1、配置RCC
2、配置SYS
3、设置PC13为GPIO_Output用于点亮LED灯
4、配置串口USART1
5、设置并完成创建工程
二、获取uCOS-III源码
进入 Micrium 公司官网下载中心：http://micrium.com/downloadcenter/选择ST系列，点击 View all STMicroelectronics，点击 STMicroelectronics STM32F107之后按照提示注册下载即可。
或者

三、移植前准备
打开下载好的文件
将文件复制添加到CubeMx生成的文件里面，如图：
四、移植过程
打开生成的keil文件
1、将uCOS文件添加到项目中
点击上面工作栏的这个图标
如图所示，在路径中将刚刚的文件添加进去
点击CPU文件夹，点Add File…将uc-CPU中的此文件添加进去
点击LIB–>Add Files…
MDK-ARM\uC-LIB路径下选中下图红框文件，Add添加
MDK-ARM\uC-LIB\Ports\ARM-Cortex-M3\RealView路径下选中下图绿框文件，Add添加
点击PORT–>Add Files…
MDK-ARM\uCOS-III\Ports\ARM-Cortex-M3\Generic\RealView路径下选中以下文件，Add添加
点击SOURCE–>Add Files…
MDK-ARM\uCOS-III\Source路径下选中以下全部 .c .h 文件，Add添加
点击CONFIG–>Add Files…
MDK-ARM\uC-CONFIG路径下选中以下全部文件，Add添加
点击BSP–>Add Files…
MDK-ARM\uC-BSP路径下选中以下全部文件，Add添加
全部添加完，记得点OK。
2、导入文件路径
如图：
五、构建任务
1、代码添加
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 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
2、部分代码修改修改部分文件相关代码
打开startup_stm32f103xb.s文件
在以下位置处将PendSV_Handler改为OS_CPU_PendSVHandler，
SysTick_Handler改为OS_CPU_SysTickHandler
打开app_cfg.h文件
DEF_ENABLED 改为 DEF_DISABLED
#define APP_TRACE BSP_Ser_Printf 改为 #define APP_TRACE(void)
打开includes.h文件
在#include <bsp.h>下面添加 #include “gpio.h” #include “app_cfg.h”
将#include <stm32f10x_lib.h> 改为 #include “stm32f1xx_hal.h”
打开lib_cfg.h文件
修改为5（该处宏定义设置堆空间的大小，STM32F103C8T6的RAM只有20K，所以要改小一点）
打开usart.c文件，添加代码完成printf重定向
/* USER CODE BEGIN 1 */
typedef struct __FILE FILE;
int fputc(int ch,FILE *f){
HAL_UART_Transmit(&huart1,(uint8_t *)&ch,1,0xffff);
return ch;
}
/* USER CODE END 1 */
初始化管脚
在gpio.c文件中修改代码
void MX_GPIO_Init(void)
{
GPIO_InitTypeDef GPIO_InitStruct = {
0};
/* GPIO Ports Clock Enable */
__HAL_RCC_GPIOC_CLK_ENABLE();
__HAL_RCC_GPIOD_CLK_ENABLE();
__HAL_RCC_GPIOA_CLK_ENABLE();
/*Configure GPIO pin Output Level */
HAL_GPIO_WritePin(GPIOC, GPIO_PIN_13, GPIO_PIN_RESET);
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_3, GPIO_PIN_RESET);
/*Configure GPIO pin : PC13|PA3 */
GPIO_InitStruct.Pin = GPIO_PIN_13|GPIO_PIN_3;
GPIO_InitStruct.Mode = GPIO_MODE_OUTPUT_PP;
GPIO_InitStruct.Pull = GPIO_NOPULL;
GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW;
HAL_GPIO_Init(GPIOC, &GPIO_InitStruct);
HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);
}
