PX5 MODULES

Simple

The Module Manager comprises one source file, px5_module_manager.c. This file can be easily added to any project. The only additional requirement is to set up the project’s include path so that px5_module_manager.h can be located during compilation. At this point, the Module Manager is ready for operation—no complicated projects and linker control file changes are necessary.

Each PX5 MODULES requires only the px5_module.c and px5_module_description.s source files and the application code. The include file px5_module.h must also be available in the path.

Module Manager Sample Code:

#include <pthread.h>
#include  <px5_module_manager.h>

unsigned char     memory[1024];

int   main()
{
    /* Start PX5 RTOS.  */
    px5_pthread_start(1, memory, sizeof(memory));

    /* Initialize the Module Manager.  */
    px5_module_manager_initialize();

    /* Create a module. The code for the module is already loaded at
       0x8000000 and RAM at 0x64000000.  */
    px5_module_manager_create(0, NULL, 0, 16, 31, 
	(void *) 0x8000000, 0x4000, (void *) 0x64000000, 0x400, NULL, 0);

    while(1)
    {
        sched_yield();
    }
}
		    

MODULE sample code:

#define PX5_MODULE_SOURCE
#include  <px5_module.h>

/* This is the module's entry function (thread).  */
void *  module_entry(void *  argument_area,  u_long  argument_size)
{
    /* Application processing goes here!  */
    while(1)
    {
        sched_yield();
    }
}

/* This is the exit function of the module, which is called before the module is terminated.  */
void  module_exit(void)
{
    /* Application processing goes here!  */
}
