Object Method Design Pattern

In the embedded systems programming in C, the Object Pattern is typically implemented using structures and functions that operate on those structures. While C does not have native support for object-oriented programming.

We can achieve similar concepts through a combination of structures and function pointers. Let’s see a simple example for illustrating the Object Pattern in C for an embedded system.

C

#include <stdio.h>
 
// Define a structure to represent an object
typedef struct {
    // Data members
    int value;
 
    // Function pointer for a method
    void (*print)(const struct MyObject *);
} MyObject;
 
// Method to print the value of the object
void printValue(const MyObject *obj) {
    printf("Object value: %d\n", obj->value);
}
 
// Function to initialize an object
void initializeObject(MyObject *obj, int initialValue) {
    obj->value = initialValue;
    obj->print = &printValue; // Assign the function pointer
}
 
int main() {
    // Create an instance of MyObject
    MyObject myObj;
 
    // Initialize the object
    initializeObject(&myObj, 42);
 
    // Use the object's method
    myObj.print(&myObj);
 
    return 0;
}

Output

Object value: 42

Explanation of the above Code:

MyObject is a structure that encapsulates data and functionality.
The printValue function acts as a method for the object, printing its value.
The initializeObject function initializes an instance of MyObject and sets its initial value.

Design Patterns for Embedded Systems in C

When working with embedded systems in C, there are so many design patterns that are particularly very useful. Many design patterns can be applied to embedded systems development in C. In this article, we will discuss design patterns for Embedded Systems in C, let’s see all of them one by one with the help of examples.
