Object-Oriented Techniques with C51

Tri Jatmiko

Hello All,

Do you know any application notes, tutorial, or example program that is using Object-Oriented Techniques in 8051 ? I heard about Abstract Data Type, Jump Table and so on.

Thanks
-Cahya

    // Becuase of the limitations of a 8051,

// I use the ClassName_Member notation on 'public' members

// Here is one example of a singleton, statically allocated class:

// ClassName.h

extrn int  ClassName_property1;
extrn char ClassName_property2;

void ClassName_Ctor(void);
void ClassName_Dtor(void);

int  ClassName_Method1(char* p);
char ClassName_Method2(void);

//
// ClassName.c
//
#include "ClassName.h"

//public:
int  ClassName_property1;
char ClassName_property2;

//private:
static int property1;
static int property2;

//public:
void ClassName_Ctor(void)
{
  ClassName_property1 = 0;
  ClassName_property2 = '\0';

  property2 = '\0';
};
//void ClassName_Dtor(void) //rarely used
//{};

int  ClassName_Method1(char* p)
{};
char ClassName_Method2(void)
{};

//private:
static int  Method1(char* p)
{};
static char Method2(void)
{};


//
// Main.h
//

static void Ctor(void)
{

  //.. other Ctors

void main(void)
{
  Ctor();
  
  ClassName_property1 = 1;
  ClassName_Method1(1);
  
  while( 1 );
}
