一、使用CubeMX建立STM32F103C8T6HAL库
还是和之前博客写的一样,建立新工程,选择STM32F103C8 配置RCC
配置SYS 设置串口USART1 设置PC13为GPIO_Output用于点亮LED灯 设置工程 点击生成代码,并在Keil中打开该工程。
在main函数中的while循环里添加语句
while (1)
{
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);
}
编译,将代码烧录到STM32F103中,BOOT0置零,按下Reset按钮,可以看到PC13LED灯闪烁,证明代码没有问题。
二、准备uCOSIII源码
进入官网下载:https://www.silabs.com/developers/micrium 或百度网盘下载:https://pan.baidu.com/s/10RqsDRecbmVteWmDv2oUNQ#list/path=%2F 提取码:1234 网盘下载,打开目录如下(文件夹uC-BSP和uC-CONFIG是自己新建的两个文件夹)
三、移植前准备
官网下载的就要进行移植前的准备,百度网盘下载的是已经移植前准备了的,可以直接到第四步
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(从以下路径复制过来)
四、开始移植
1.将uCOS相关文件复制到HAL工程的MDK-ARM文件夹下 2.将uCOS文件添加到项目 回到Keil打开的HAL工程 点击Manage Project Items 为项目新建文件夹如下 分别给新增的文件夹添加文件 注意,文件类型要选择All files 点击CPU–>Add Files…,将uC-CPU中的cpu_core.c、cpu_core.h、cpu_def.h添加进CPU组中,同时将uC-CPU/ARM-Cortex-M3/RealView中的三个文件添加到该组,点击Add添加: 点击LIB–>Add Files…,将uC-LIB中的9个文件添加到LIB组中,同时将uC-LIB/Ports/ARM-Cortex-M3/Realview中的lib_mem_a.asm添加到该组中: 点击PORT–>Add Files…,将uCOS-III/Ports/ARM-Cortex-M3/Generic/RealView中的3个文件添加的PORT组中: 点击SOURCE–>Add Files…,将uCOS-III/Source中的20个文件添加到SOURCE组中: 点击CONFIG–>Add Files…,将uC-CONFIG中的8个文件添加到CONFIG组中; 点击BSP–>Add Files…,将uC-BSP中的2个文件添加到BSP组中; 然后点击ok 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
五、文件内容的修改
1.bsp.h
找到BSP下的bsp.h 添加代码如下
#ifndef __BSP_H__
#define __BSP_H__
#include "stm32f1xx_hal.h"
void BSP_Init(void);
#endif
2.bsp.c
找到BSP下的bsp.c 添加以下代码
#include "includes.h"

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

}
#if (CPU_CFG_TS_TMR_EN == DEF_ENABLED)

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

{
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.main.c

4.启动文件
将启动文件下图中的PendSV_Handler和Systick_Handler改为OS_CPU_PendSVHandler和OS_CPU_SysTickHandler
5.app_cfg.h
将#define APP_CFG_SERIAL_EN DEF_ENABLED修改为#define APP_CFG_SERIAL_EN DEF_DISABLED 将#define APP_TRACE BSP_Ser_Printf改为#define APP_TRACE (void)
6.includes.h
#include <bsp.h>处添加 将#include <stm32f10x_lib.h>修改为#include “stm32f1xx_hal.h”
7.lib_cfg.h
此处修改为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)
8.usart.c
由于我们使用了printf函数,需要在usart.c文件中添加以下代码完成printf重定向
int fputc(int ch,FILE *f){
HAL_UART_Transmit(&huart1,(uint8_t *)&ch,1,0xffff);
return ch;
}
同时要加入typedef struct __FILE FILE;
9.参数配置
六、运行
烧录(可以看之前的博客) 板子上运行效果如下(可以看到PC13和RXD的指示灯在闪烁,说明在发送数据):
调试助手打开串口效果如下:
七、实现三个任务
3个任务(task):其中两个task分别以1s和3s周期对LED等进行点亮-熄灭的控制;另外一个task以2s周期通过串口发送“hello uc/OS! 欢迎来到RTOS多任务环境!”。 gpio.c中修改代码(添加初始化PA3) 将void MX_GPIO_Init(void)改为下面这个
void MX_GPIO_Init(void)
{
GPIO_InitTypeDef GPIO_InitStruct = {0};
__HAL_RCC_GPIOC_CLK_ENABLE();
__HAL_RCC_GPIOD_CLK_ENABLE();
__HAL_RCC_GPIOA_CLK_ENABLE();
HAL_GPIO_WritePin(GPIOC, GPIO_PIN_13, GPIO_PIN_RESET);
HAL_GPIO_WritePin(GPIOA, GPIO_PIN_3, GPIO_PIN_RESET);
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);
}
修改main.c,全部改为下面的代码
