Basic Steps to Be Followed for Developing an Embedded Program

Basic Embedded C program is the preferable language for programming embedded systems due to its portability, efficiency, and lowered development time. Programming languages like BASIC, Python, Assembly, C++, etc., are also used for developing embedded systems. 

 

What is an Embedded System?

It is a system of software and hardware designed to perform a predetermined function within a complex and larger system. 

A washing machine is the best example of an embedded system used in all households.

Electronic components of a car are also examples of embedded systems. 

A few examples of embedded systems in modern-day cars are temperature monitoring systems, engine oil monitoring systems, anti-lock braking systems, tire pressure monitoring systems, and automatic climatic control, among others. 

What Is Embedded Programming?

Embedded programming is also called embedded systems programming or embedded software development. 

Embedded programming manages the microcontroller at the heart of all embedded electronic equipment. Software for onboard automotive computers and small smart devices such as handheld games, thermostats and other devices use embedded programs.  

 

Factors for Selecting the Programming Language

 

• Speed: The programs should be quick. The chosen software should not slow down the hardware. 

 

• Size: Space is a luxury in embedded processors like microcontrollers, which have a restricted amount of ROM (Program Memory). 

 

• Portability: The program should be multi-system compliant. 

 

• Alleviate Implementation
• Readability
• Ease of Maintenance

Initially, engineers designed embedded systems exclusively using assembly language. Even though assembly language is nearest to the actual machine code instructions and generates small hex files, the usage of high values resources and lack of portability reduce the ease of operation of the code.

The C programming language, however, does not have these limitations.

 

 

Essential Toolkit Before Programming

You should know a basic knowledge of these essential factors before developing a code for your idea. 

1. Basics of Electronics

If you lack a basic knowledge of electronics, it increases the difficulty of designing any embedded programming system. An embedded system is not just about writing a program. Its purpose is to make a complete design that will influence physical objects to perform the desired task.

2. Choose a Programming Language

Choosing a programming language is the primary step in developing embedded software. The language can be high-level or low-level programming, as each has its benefits. However, as mentioned earlier, C programming is preferred by various programmers. 

3. Know Your Microcontroller

In a total embedded system, the microprocessor or microcontroller is crucial. It works like the CPU of the embedded system. Generally, 8051, PIC Microcontroller, or Arduino are used as microcontrollers. When choosing a microcontroller, the software prerequisite is a significant aspect.

4. Gather Your Equipment and Tools

You can begin to gather circuit boards, resistors, soldering iron, jumper wires, and batteries to get a deep understanding of the embedded system. But, of course, the equipment sheet will differ from one project to another. 

5. Select Components

Component selection is an essential part of understanding embedded programming. For each element, the datasheet is available, but you need to learn how to understand the datasheet. 

 

Job Opportunities for Embedded Systems

After deciding on the appropriate technology, programming language, and platform, the full technical environment may be set up.

It's crucial to document one's code during development is crucial for forwarding and backward compatibility. 

After ensuring that each piece of the engineer's "software puzzle" (unit tests) work as intended, they will double-check that the embedded system works together properly before delivery (integration tests). Consequently, the established set must naturally match the expectations. 

The average yearly income for an embedded systems engineer in India is 4.5 lakhs, with salaries ranging from 1.9 lakhs to 15.9 lakhs. 

 

Conclusion

The electronics business is built on embedded solutions, which are also the basis of daily living. In addition to many other industries, people utilise gadgets with built-in software functionalities in healthcare, transportation, and commerce. As a result, there will be a greater need for professional embedded software developers shortly.
