[嵌入式]STM32F103C8T6移植uCOS系统基于HAL库

一、用CubeMX建立HAL库

设置PC13作为GPIO_Output口来点亮LED灯。



点击GENERATE CODE来生成工程并打开。
在main.c里面添加代码：

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 */

编译烧录，可以成功点亮LED灯，完全没有问题。

二、准备uCOSIII源码

学长提供的下载链接：源码下载
密码：1234

三、准备移植

1.在uC-CONGFIG添加文件

现在这个目录下找到这些文件。

复制完成后结果。

2.复制文件到MDK-ARM文件夹下

复制这五个文件。

复制完成后的结果。

四、开始移植

1.新建六个文件夹

2.开始给每个文件夹分别添加文件

CPU文件夹：



LIB文件夹：



PORT文件夹：


SOURCE文件夹：

CONFIG文件夹：


BSP文件夹：


点击OK进行保存（切记）。

3.导入文件路径

点击OK完成保存（里外都要）。

4.为bsp.c和bsp.h添加代码

①bsp.h

// bsp.h
#ifndef  __BSP_H__
#define  __BSP_H__

#include "stm32f1xx_hal.h"

void BSP_Init(void);

#endif

②bsp.c

#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

6.修改其他的代码

startup_stm32f103xb.s：

                DCD     OS_CPU_PendSVHandler             ; PendSV Handler
                DCD     OS_CPU_SysTickHandler            ; SysTick Handler

OS_CPU_PendSVHandler  PROC
                EXPORT  OS_CPU_PendSVHandler             [WEAK]
                B       .
                ENDP
OS_CPU_SysTickHandler PROC
                EXPORT  OS_CPU_SysTickHandler            [WEAK]
                B       .

app_cfg.h：

#define  APP_CFG_SERIAL_EN                          DEF_DISABLED

#define  APP_TRACE(void)

includes.h：

#include "gpio.h"
#include "app_cfg.h"

#include  <stm32f1xx_hal.h>

lib_cfg.h：

将这一行的20改成5。

usart.c：

/* USER CODE BEGIN 1 */
int fputc(int ch,FILE *f){
	HAL_UART_Transmit(&huart1,(uint8_t *)&ch,1,0xffff);
	return ch;
}
/* USER CODE END 1 */

特别提醒需要在usart.c里对FILE重新定义否则会报错：

typedef struct __FILE FILE;

将这行代码添加到usart.c。

7.配置参数

编译无错后就可以直接烧录进去，查看运行效果。会看到PC13一直亮说明在传输数据。

8.运行结果

五、三个任务实现

1.代码修改

gpio.c中修改代码（添加初始化PA3）：

void MX_GPIO_Init(void)
{

  GPIO_InitTypeDef GPIO_InitStruct = {0};

  /* GPIO Ports Clock Enable */
  __HAL_RCC_GPIOC_CLK_ENABLE();
  __HAL_RCC_GPIOD_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;

2.运行结果

六、逻辑仪观察波形

可以看到PC13是1s亮一次，然后PA3是3s亮一次。

七、总结

本次实验通过参考学长学姐的博客，比较快速的完成了实验的操作，但是对于代码的理解比较一般，另外也没有在课堂的时间内用逻辑分析仪分析波形，只能通过仿真来观察。
