Delete main.c file .

1. Open the project , Remove the obsolete file first , Then click engineering structure in the toolbar （ Three square pieces ）, Establish corresponding folder engineering structure , Add the following five folders （APP,BSP,UC-CPU,UC-BSP,UCOS-III） Pictured 6 Shown .

chart 6 Establish a file structure

Then add the corresponding project file to the corresponding file , stay APP Add under the folder corresponding to User\APP All under folder .c file , Pictured 7 Shown .

chart 7 add to APP File structure

stay BSP Add under the folder corresponding to User\BSP All under folder .c file 、User\BSP\Key All under the folder .c file ,User\BSP\Led All under the folder .c file ,User\BSP\usart All under the folder .c file , Pictured 8 Shown .

chart 8 add to BSP File structure

stay uc-cpu Add the corresponding file under the folder , add to User\uC-CPU All under the folder .c file 、 add to User\uC-CPU\ARM-Cortex-M4\RealView All under the folder .c and .asm file , Pictured 9 Shown .

chart 9 add to uc-cpu File structure

stay uc-lib Add the corresponding file under the folder , add to User\uC-LIB All under the folder .c file 、 add to User\uC-LIB\Ports\ARM-Cortex-M4\RealView All under the folder .c and .asm file , Pictured 10 Shown .

chart 10 add to uc-lib File structure

stay ucos-iii Add the corresponding file under the folder , add to User\uCOS-III\Source All under the folder .c file 、 add to User\uCOS-III\Ports\ARM-Cortex-M4\Generic\RealView All under the folder .c and .asm file , Pictured 11 Shown .

chart 11 add to ucos-iii File structure

Click... After adding OK.

1. Add the corresponding folder header file path to the project , Click the compile Properties menu in the toolbar （ Magic wand ）, And then choose C/C++ That column , stay include paths Add the corresponding header file directory in , Pictured 12 Shown .

chart 12 Add header Directory

Click... After adding OK.

1. modify startup_stm32f429_439xx.s file , Modify... In the startup file PendSV_Handler and SysTick_Handler Change the distribution to OS_CPU_PendSV_Handler and OS_CPU_SysTickHandler. Pictured 13 Shown .

chart 12 modify PendSV_Handler And SysTick_Handler

I'm jumping in main After that, add a floating-point running function , Pictured 13 Shown .

chart 13 Add floating point operation processing

1. modify bsp.h and bsp.c file , First modify bsp.h file , Header file modification , Add header file in board level support package , And keep the three function declarations , Others can be deleted , Pictured 14 Shown .

chart 14 bsp.h File modification

Revise bsp.c file , Delete ucos-iii Self contained STM32 Macro definition of onboard driver , Delete uc-iii Self contained STM32 On board drive function , Clear all definitions of onboard initialization function , Use bare metal driver functions instead , Delete other irrelevant code , Pictured 15 Shown .

chart 15 modify bsp.c file

7, modify app.c file , Mainly to increase their own tasks .
