[Shanghai Hangxin ACM32F070 development board review] 6. Transplant the RTX operating system [Copy link]

 

Recently, a high-level company held a lecture on the UCOS operating system. I was furious when I heard it, because the porting of UCOS is too troublesome. I have said it before, do you dare to use it in your product after porting it? ? ?

I was reminded of KEIL’s RTX operating system, which does not require any porting, just a check mark.

This time I will move it to the Shanghai Hangxin ACM32F070 development board. Why not take a shortcut? Besides, RTX also has a file system and a GUI.

The first step is to check the box: find the green diamond in the MDK menu

Step 2: Write your own program

1. Use the last watchdog program to delete the dog first, and include the header file at the beginning of the MAIN function: #include "cmsis_os.h"

After including the header file, the definition is as follows:

void led_Thread1 (void const *argument);

osThreadDef(led_Thread1, osPriorityNormal, 1, 0);

osThreadId T_led_ID1;

And write the led_Thread1 function:

void led_Thread1 (void const *argument)
{
	while(1)
	{
	printfS("HELLO EEWORLD !!!"); 
	osDelay(500);
	}
}

Step 3:

Then compile, and it will prompt that the SYSTICK program definition is repeated.

Disable the SYSTICK function in System_ACM32F0x0.c and compile it again.

Operation results:

This ACM32F070 RTX OS porting method is great

The transplantation of UCOS is too troublesome. Can you explain it in detail? I am curious.

UC/CPU transplant file package inserts 7 files: CPU_DEF.h, CPU_CORE.h, CPU_CORE.C, CPU_CFG.H, CPU_C.C and CPU_A.ASM

UC/LIB file package inserts 11 files: omitted

UC/OS configuration file inserts 4 files: OS_CFG.h, OS_APP_HOOKS.H, OS_APP_HOOKS.C and OS_CFG_APP.H

The UC/CSP file includes 11 files:

slightly

UC/BSP files:

Includes 3 files:

I don't quite understand. I remember that for Linux and other transplants, you also need to modify many header files and configurations.

Do you find it complicated because there is no graphical interface for configuration?

Yes, UCOS does not have a graphical interface. Now I am very disgusted with Linux, which has a graphical interface. I feel that it is not as good as DOS.
