V. operation results

Vi. reference website

1, Get uC/OS-III source code

1. Download from the official website

Enter the download center of Micrium's official website: Micrium Software and Documentation - Silicon Labs
Select ST series, click View all STMicroelectronics, select the corresponding version and download it

2. Network disk download

Because the official website download is sometimes slow and troublesome, so post Baidu online disk

Link: https://pan.baidu.com/s/1_Wk-hbeQ7KrvnoA0GwJXdA  
Extraction code: qwer

2, Source code import file sorting

2.1 creating new folders and files

Open the downloaded source code

Create two new folders, UC BSP and UC config.

  Open UC BSP   Create bsp.c and bsp.h files

two point two    Import source code

Open the downloaded source code and copy all. C. H files under Micrium\Software\EvalBoards\Micrium\uC-Eval-STM32F107\uCOS-III to Micrium \ software \ UC config

three   Create stm32cubeMX project and provision

3.1 stm32cubemx project creation

Select the chip stm32f103RC and configure the system clock as 72M. As a migration test, configure the two ports PB0 and PB1 connected to the LED as GPIO_Output, which can be used as the basis for our successful transplantation according to the LED phenomenon.

Configure RCC

  Configure SYS

Set serial port USART1

  Two ports PB0 and PB1 are configured as GPIO_Output

Setup project

3.2 project configuration

Import the source folder just created into the cubemx project directory just created

  Open keil and add item   Add six groups

 

  BSP adds the blank files bsp.c and bsp.h just created.

Add 8 files under CONFIG

Add 20 files in SOURCE

 

Add 3 files under PORT

Add 6 files under CPU  

Add 10 files under LIB  

  Then modify the file compilation path

Click on the magic wand

IV. code modification  

4.1 modify startup file

take                                     Change to

PendSV_Handler    ----->      OS_CPU_PendSVHandler

SysTick_Handler     ----->      OS_CPU_SysTickHandler

4.2 modify CONFIG/app_cfg.h


Put #define APP_CFG_SERIAL_EN         DEF_ENABLED  

Change to #define APP_CFG_SERIAL_EN         DEF_DISABLED

Put #define app_ TRACE BSP_ Ser_ Change printf to #define APP_TRACE (void)

 

4.3 modify CONFIG/includes.h   

Add after #include < BSP. H >
                    #include "gpio.h"
                    #include "app_cfg.h"

Set #include < stm32f10x_ Change lib. H > to #include "stm32f1xx_hal.h"
