What you need to know about embedded software development

More than 50 years ago, the introduction of the first embedded system marked the beginning of a remarkable journey. Fast-forward to today, and we find ourselves surrounded by countless embedded systems that play a key role in shaping our technology landscape. Notably, these systems have also become an indispensable component in the development of Internet of Things (IoT) devices. However, it is important to realize that the development of embedded software requires its own unique sophistication and complexity.

In this article, we delve deeper into the fascinating world of embedded software, exploring its nature and the complex process for creating these systems.

Embedded Software Definition

Embedded software represents a powerful system that is meticulously crafted and integrated into various devices beyond the realm of conventional computing. In essence, it serves as the intellectual core, giving purpose and functionality to an inert device. Without embedded software, such devices would be completely useless, without any meaningful operation.

Stay tuned as we unravel the intricate layers of embedded software development, unravel its inner workings, and reveal the secrets to creating sophisticated and efficient systems.


Examples of embedded software

Embedded software finds its expression in countless everyday devices, from rudimentary to advanced. First, let’s explore some simple cases of embedded software, such as traditional computers that were once primary devices before their functions were integrated into smartphones. Likewise, the remote control of modest TVs and digital cameras is indispensable thanks to embedded systems.

Now, you may be wondering if embedded systems revolve around software development only. The answer is not always simple. In some cases, the term “firmware” is also used to describe simpler devices like the aforementioned examples.

However, it is important to realize that embedded technologies go far beyond the scope of conventional devices such as coffee machines. To give you a glimpse into the diverse landscape of embedded software, here are some fascinating and innovative examples:

  • connected car: The emergence of connected cars has ushered in a new era of automotive technology, requiring meticulous attention to quality and safety standards. Embedded software plays a key role in these vehicles, with thousands of lines of code meticulously crafted to enable seamless connectivity, advanced driver assistance systems and an enhanced user experience. .

  • Smart digital camera: In the field of smart digital cameras, embedded software plays a central role in powering internal systems. These sensor-driven cameras have remarkable features such as facial recognition and recognition, all made possible by the complex programming embedded within. In addition, the integration of artificial intelligence and machine learning further enhances their capabilities, paving the way for stunning images and smart camera functions.

  • Smart parking software: Smart parking apps work on a similar principle, relying on embedded programming as the heartbeat for their functionality. Integrated electronics serve as the backbone of these applications, supporting efficient parking management, real-time user tracking and a seamless user experience. By leveraging embedded software, smart parking solutions optimize parking space utilization and streamline the overall parking process.

Basic components of an embedded system

The basic components of an embedded system include the embedded hardware, software, and operating system. Let’s explore each of these components in more detail:

  1. Hardware:

    1. User Interface: This component includes the features, buttons, and actions available to the user, usually accompanying the screen.

    2. Memory: Embedded systems can include both Random Access Memory (RAM) and Read Only Memory (ROM) to store and access data and instructions.

    3. Power Source: The power source determines how the system is charged, whether via an electrical outlet or a battery.

    4. Timers: Some embedded systems incorporate timers to measure intervals and trigger specific actions. For example, a smart home system could use a timer to automatically turn off lights after a certain period of inactivity.

    5. Communication ports: Embedded systems rely on different communication ports to interact with other devices or systems. Examples include USB ports, Controller Area Network (CAN), Link Integrated Circuits (I2C), SAE J1587/J1708, Serial Peripheral Interface (SPI), Universal Serial Bus (USB), Kit Universal asynchronous receiver/transmitter (UART) and Firewire.

  2. Software:

Embedded software: software development involves generating machine code in specific programming languages ​​such as C and C++. This software enables the desired functionality and operation of the embedded system.

  1. Embedded OS:

Real-time operating system (RTOS): An embedded operating system is a specialized layer of software that manages resources and provides essential services for an embedded system. Typically, RTOS is used to ensure accurate timing and responsiveness in real-time applications.

In addition to core components, embedded software engineers use different tools for development and design purposes. Some of the key tools include:

  • Editor: Used to write and edit code in programming languages ​​like C or C++.

  • Compiler: Converts high-level programming language code into low-level machine code.

  • Assembler: Required when programming code is written in assembly language, performing the same task as a compiler.

  • Debugger: Helps identify and eliminate bugs and errors in software.

  • Linker: Combines pieces of code and modules to create an executable program.

  • Emulator: Allows embedded system engineers to test program performance in a simulated real-world environment, facilitating improved user experience.

These tools and components are critical to the development and deployment of powerful and efficient embedded systems.

Embedded Software Development Challenge

Embedded software development, especially in the context of the Internet of Things (IoT), poses unique challenges that need to be addressed for successful implementation. Let’s explore some of the following challenges:

  1. Stability: In cases where the device has the potential to affect the user’s safety, ensuring stability is extremely important. Unforeseen or erratic behavior is unacceptable, requiring a standard approach to system development that prioritizes reliability and consistent performance.

  2. Safety: Embedded systems are often deployed in mission-critical environments where proper functioning of a life-saving function is critical. It is imperative to develop embedded software in a way that prioritizes safety, ensures that the system works reliably, and minimizes any risk to the user or surrounding individuals.

  3. Security: Embedded software is intimately connected to specific devices, often controlled via mobile apps. This integration creates a potential security hole, making it necessary to address the risk of data hijacking and unauthorized access. Strong security measures should be in place to guard against potential breaches and protect sensitive information.

Considering these challenges, manufacturers who are venturing into embedded software development should look for a Trusted development partner. Working with a trusted partner who can provide valuable expertise and support throughout the development process ensures the creation of high-quality solutions that meet industry standards.
