Top 10 Embedded Software Development Tools

Digital transformation is touching upon various physical objects, making them smart and powerful. The engine for such devices is embedded software that is an integral part of the rapidly developing IoT ecosystem.

This article is dedicated to the tools for embedded software development. We will explain what an embedded system is and what types of tools are needed to build one. You will also learn about the most popular embedded system software development tools currently available on the IT market.

What is Embedded Software?

If traditional desktop software is written for computers, embedded software is integrated into non-computer hardware to control its functions. The hardware is represented by various monitoring devices, machines, sensors, wearables and practically every piece of modern electronics. Embedded technology, together with networks and information technologies, constitutes the Internet of Things systems and is widely used in medicine, manufacturing, appliances, the automotive industry, transportation and aviation.

The core difference between desktop and embedded programming lies in their purposes. General computers are used for multiple purposes, which is why their software can be installed on numerous devices and can be easily reconfigured. Embedded software, on the contrary, serves a single purpose and is created specifically for a certain device it should run on.

In addition, embedded solutions are developed taking into account environmental factors such as temperature or humidity that may influence devices and affect their performance.

An embedded system is a combination of a hardware module and a software module.

To assemble hardware, the following basic components are needed:

• A power supply
• SoM (System-on-a-Module)/SoC (System-on-a-Chip) — a combination of microprocessors, peripherals, memory, I/O on a single board

To create software, the following basic components are needed:

• Operating systems (Windows CE, Yocto Linux, ThreadX, Nucleus RTOS)
• Languages (C, C++, Python, JavaScript, etc.)
• Tools (IDE, PDK, SDK, compiler toolchains, hardware and software debuggers (e.g. ST-Link, Segger))

Schematically, an embedded system can be depicted as follows:

Types of Embedded Software Development Tools

The following is the list of the types of embedded software development tools with their description.

Editor

A text editor is the first tool you need to begin creating an embedded system. It is used to write source code in programming languages C and C++ and save this code as a text file.

A good example of a text editor is Geany. This is a small and lightweight environment that uses the GTK+ toolkit. Geany supports C, Java, PHP, HTML, Python, Perl, Pascal and other types of files.

Basic functions of Geany:

• Syntax highlighting
• Code folding
• Symbol name auto-completion
• Snippets
• Auto-closing of XML and HTML tags
• Code navigation

Compiler

Source code is written in a high-level programming language. A compiler is a tool for transforming the code into a low-level machine language code — the one that a machine can understand.

Keil C51 is a popular compiler that creates apps for 8051 microcontrollers and translates source code written in the C language.

Assembler

The function of this tool is to convert a human-written code into a machine language. In comparison with a compiler, which can do so directly, an assembler initially converts source code into object code, and then to a machine language.

GNU Assembler (GAS) is widely used for Linux operating systems and can be found in the Macintosh tools package.

Debugger

This is a critical tool for testing. It goes through the code and eliminates bugs and errors, notifying places where they occur. Precisely, debuggers pinpoint the lines where issues are found, so programmers can address them quickly.

A good debugger tool is IDA Pro that works on Linux, Windows and Mac OS X operating systems. It has both free and commercial versions and is highly popular among developers.

Linker

Traditionally, code is written into small pieces and modules. A linker is a tool that combines all these pieces together, creating a single executable program. GNU ld is one of the linker tools.

Emulator

An emulator is a replication of the target system with identical functionality and components. This tool is needed to simulate software performance and to see how the code will work in the real-time environment. Using emulators, programmers can change values in order to reach the ideal performance of the code. Once the code is fully checked, it can be embedded in the device.

Integrated Development Environment (IDE)

Talking about the list of embedded software development tools, we cannot but mention integrated development environments. All the above-mentioned tools are needed for creating your embedded software. But it would be extremely inconvenient to use them separately, adding another layer of complexity to the project.

Hence, to simplify the development process, it is highly recommended to use integrated environments. IDE is software that provides a set of necessary tools in one package.

Embedded Software Development Tools List

For your information and convenience, we have compiled an embedded software development tools list, gathering the most popular solutions in the market.

1. PyCharm

A Czech company JetBrains created this IDE specifically for developers working with Python. Nevertheless, PyCharm is suitable for cross-platform development as it supports JavaScript, CoffeeScript, TypeScript, Cython, SQL, HTML/CSS, AngularJS, Node.js, template languages, and more, together with Windows, macOS and Linux operating systems.

PyCharm provides everything you need for productive embedded software development:

• Intelligent code completion
• Error highlighting and fixing
• Automated code refactoring
• Easy project navigation
• Support for web development frameworks such as Django, Flask, Google App Engine, Pyramid, and web2py
• Integrated testing
• Remote development on virtual machines

PyCharm offers the community, professional and educational editions, proving to be a perfect tool for various programming purposes.

2. WebStorm

Another IDE from JetBrains is WebStorm, used for creating JavaScript, CSS and HTML solutions.

WebStorm performs autocompletion, on-the-fly code analysis, code navigation, refactoring, debugging and integration with version control systems. It also supports multiple nesting e.g. when a JS script is embedded in an HTML document, in which another HTML code is embedded, inside which JavaScript is embedded. The organization of information in these layers provides correct refactoring.

3. Qt Creator

Qt integrated development environment has a comprehensive set of libraries, APIs and tools to create software for embedded devices in C++, JavaScript and QML.

• Live syntax checker — this feature is able to detect common errors, reducing the total number of errors at the end of the compilation
• Dashboard window — contains useful information on the project properties

5. Visual Studio

A popular integrated development environment by Microsoft — Visual Studio — is used to build not only computer programs and mobile apps, but embedded software as well. The extension Visual C++ for IoT development enables programmers to debug native C/C++ code either locally on Windows, or on microcontrollers, or on remote Linux machines. Using Visual Studio for IoT, you can build, edit and debug devices running on Linux.

VisualGDB provides an interface between Visual Studio and the GNU toolchain to build and debug embedded firmware. Thus, you can configure your project by implementing third-party compilers and tools.

6. Eclipse

Initially, the Eclipse integrated development environment was created for Java applications, and now it is the most widely used solution by Java programmers. Nevertheless, Eclipse can work with other programming languages (Ada, ABAP, C, C++, C#, Python, PHP, etc.) via plug-ins.

A separate package — Eclipse IDE for Automotive Software Developers — contains tools and frameworks for quick and easy creation of embedded automotive software.
