Essential Embedded Software Development Tools for a Smooth Development Process
Tumblr media
Embedded software development is a specialized field that requires a unique set of tools to ensure the smooth creation of software that runs on embedded systems, such as microcontrollers and microprocessors. These tools are essential for debugging, testing, and optimizing code for these resource-constrained environments. In this blog post, we’ll explore some of the key embedded software development tools that every developer should have in their toolbox.
Integrated Development Environments (IDEs)
IDEs are the central hub for embedded software development. They provide a comprehensive platform for writing, editing, compiling, and debugging code. Some popular IDEs for embedded development include:
Eclipse: An open-source IDE with a vast ecosystem of plugins, including many tailored for embedded development.
Keil MDK: A dedicated IDE for ARM-based microcontrollers.
IAR Embedded Workbench: A powerful toolchain for ARM, MSP430, and RISC-V processors.
PlatformIO: An open-source IDE that supports multiple platforms, including Arduino, ESP8266, and STM32.
Cross-Compilers
Cross-compilers are essential tools that allow you to write and compile code on a host machine while targeting a different architecture, like an ARM-based microcontroller. These compilers help optimize code for the target hardware. Popular cross-compilers include GCC (GNU Compiler Collection), ARM Keil, and IAR Embedded Workbench.
Debugging Tools
Debugging is a crucial aspect of embedded software development. Without the right tools, finding and fixing bugs can be a daunting task. Some of the tools used for debugging embedded systems are:
JTAG Debuggers: These hardware tools connect to your embedded system and enable you to halt program execution, inspect variables, and trace program flow.
Serial Debuggers: These are essential for debugging when using serial communication with your embedded system.
GDB (GNU Debugger): GDB is a popular open-source debugger that can be used with various IDEs and hardware debuggers.
Real-Time Operating Systems (RTOS)
Many embedded systems require real-time capabilities, and an RTOS is often the best way to achieve this. Popular RTOS options include FreeRTOS, Micrium uC/OS, and VxWorks. These operating systems help manage tasks, priorities, and resources in an embedded system.
Code Analysis and Profiling Tools
Code analysis and profiling tools are essential for optimizing code and identifying potential issues. Tools like Lint, Cppcheck, and Static Analysis Tools can help find code quality and security issues, while profiling tools like Gprof and Percepio Tracealyzer can help identify performance bottlenecks.
Version Control Systems
Effective version control is crucial for collaboration and code management. Tools like Git and SVN help keep track of code changes, facilitate collaboration, and provide a backup for your work.
Simulation Tools
Simulation tools allow you to test your embedded code on a host machine before deploying it to the target hardware. Tools like QEMU and Simulink can help you validate your code without the need for physical hardware.
Documentation and Collaboration Tools
Proper documentation is essential for understanding and maintaining embedded software. Tools like Doxygen can automatically generate documentation from code comments. Collaboration tools like Slack, Microsoft Teams, or even a simple Wiki can help teams work together efficiently.
Conclusion
Embedded software development can be a challenging but rewarding field. Having the right tools at your disposal can make the process much more manageable. Whether you are a beginner or an experienced developer, these tools can help streamline your development process, improve code quality, and ensure the reliability of your embedded systems. Make sure to choose the tools that best suit your project requirements and hardware platform for a successful embedded software development journey.

What is an Embedded System?
An embedded system is a combination of computer hardware and software designed for a specific function. Embedded systems may also function within a larger system. The systems can be programmable or have a fixed functionality.
For example, a fire alarm is a common example of an embedded system which can sense only smoke.
Tumblr media
Examples of standalone embedded systems include:
Digital cameras.
Digital wristwatches.
MP3 players.
Appliances, such as refrigerators, washing machines, and microwave ovens.
Temperature measurement systems.
Calculators.
History of Embedded system
In 1960, embedded system was first used for developing Apollo Guidance System by Charles Stark Draper at MIT.
In 1965, Auto-netics, developed the D-17B, the computer used in the Minuteman missile guidance system.
In 1968, the first embedded system for a vehicle was released.
Texas Instruments developed the first microcontroller in 1971.
In 1987, the first embedded OS, VxWorks, was released by Wind River.
Microsoft’s Windows embedded CE in 1996.
By the late 1990s, the first embedded Linux system appeared.
The embedded market reach $140 billion in 2013.
Analysts are projecting an Embedded market larger than $40 billion by 2030.
Tumblr media
Various Types of Embedded System: -
A Raspberry Pi an embedded system: Raspberry Pi single-board computer (SBC) was originally designed as a platform to teach computer science to students, but it has expanded into other applications, including use as an embedded platform.
ATM an embedded system: An Automated Teller Machine (ATM) - is an embedded system which utilizes a crowded computer to set up a network between a bank computer and an ATM itself. It also has a microcontroller to bear both input and output operations
Alexa an embedded system: The Amazon Echo is the epitome of an Internet of Things (IoT) device. It combines an embedded applications processor from Texas Instruments, MEMS microphones from Knowles, Wi-Fi and Bluetooth wireless connectivity, an AWS cloud backend, and support for diverse applications.
Smart TV an embedded software: Embedded software comes into play in “smart TVs.” Smart TVs still have firmware for the low-level signal processing tasks, and more firmware to operate the wired or wireless network interface and communications with the remote control (which also now has firmware)
Embedded System Design: -
Embedded system is a self-contained, microprocessor-based computer system typically implemented as a component of a larger electrical or mechanical system. At the core of the embedded system is an integrated circuit that performs computational tasks.

Writing ssh shell from labview on compactrio
Tumblr media
WRITING SSH SHELL FROM LABVIEW ON COMPACTRIO HOW TO
WRITING SSH SHELL FROM LABVIEW ON COMPACTRIO FULL
WRITING SSH SHELL FROM LABVIEW ON COMPACTRIO SOFTWARE
Step 1: Enabling Secure Shell Server (sshd) If using the myRIO, the easiest way to do this is to configure the Wi-Fi interface to that it connects to your internet hotspot and acquires address, dns, gateway via dhcp. Without internet access, this will not work. NOTE: All steps assume the cRIO has internet access. This tutorial will guide you through the process. This may sound hard, but it really isn't. This includes setting up the build environment on the cRIO, cloning the git repository for the rtl-sdr library, and finally compiling the code. This tutorial therefore focuses on this portion:īefore beginning with actual Labview programming, we need to prepare the cRIO. The next tutorial will implement and FPGA FFT to accelerate things, and in chapter 4 we will put this whole thing together into a coherent, expandable system. In this tutorial, we will be focusing on getting the rtl-sdr library working on in the cRIO.
WRITING SSH SHELL FROM LABVIEW ON COMPACTRIO FULL
This leads the reader chapter by chapter to a full solution, and hopefully makes things more understandable. In order to keep the reader interested and to keep the chapters short and manageable, I have decided to split things up a bit. Simply put, we want to turn the myRIO into an SDR-instrument that we can send commands to and have it return processed data to the host. However, it also makes things more complicated because a command framework is required from the Host PC to the cRIO RT target. This has the advantage of getting rid of the latency of the USB LAN connection during acquisition. In order to shorten this path it is possible to perform the acquisition directly on the cRio RT target. The FFT and other DSP is done in the FPGA and the resulting information flows back up to the PC. The information flows from the RTL-SDR to the Host PC via USB, then to the RT system via USB LAN (in the myRIO case), then to the cRio FPGA via a DMA FIFO. If the host is used for acquisition, the information flow is pictured above. If we want to use the cRIO (especially the FPGA) to accelerate digital signal processing, it is necessary to stream the information to the RT system, and then to the FPGA. The myRIO used here has the following parameters: NOTE: All development was done using Labview 2016, 32-bit. Unfortunately, there is probably no reasonable way to compile this library on VxWorks, much less Pharlap, so users of older CompactRIO devices are on their own. I used a myRio to do this project, but it should be possible to use this information on any linux-based cRio.
WRITING SSH SHELL FROM LABVIEW ON COMPACTRIO HOW TO
In this post I will go a step further and show the reader how to compile the rtlsdr library directly on an RTLinux cRIO. Additionally, because the library is open source, header files and with that the library’s entry points are available to us in a usable and documented format. The implementation process was very straightforward because the library was already compiled and available in binary form.
WRITING SSH SHELL FROM LABVIEW ON COMPACTRIO SOFTWARE
In my previous post ( ), I released a library which allows a Labview user on Windows to directly use RTL-based software defined radios.

Industrial Control Systems: A Security Analysis
Industrial control systems (ICS) are an integral part of most major industries. These control systems were initially created to help manage large-scale operations and provide more stability to them than manual methods. As the technology has advanced and become more accessible, however, more people are using it for malicious purposes. In this article we will explore some of these threats as well as ways that organisations can secure their industrial control systems against cyberattacks.
Introduction
We are all dependent on industrial control systems (ICS) for everything from running our homes to managing the power grid. The ICS is a complex system of computers, software, sensors and actuators that monitor environmental conditions and ensure the safe operation of industrial processes.
In this paper we consider the security properties of ICS from a theoretical perspective: What are their vulnerabilities? How easily can they be compromised? How can we build defenses against attacks on them? We provide answers using formal methods drawn from information theory, cryptography, game-theoretic analysis and machine learning.
The Role of Information Security
Information security is a growing concern for the information technology community. The importance of information security has grown exponentially over the last few years, and industrial control systems (ICS) present unique challenges to ensure that they are secure from both internal and external threats.
The increased connectivity among ICS networks makes them more susceptible to attacks than ever before, which means that it's important to implement standards for these systems so companies can be sure they're protected.
Tumblr media
Computer Architecture
The architecture of the ICS itself can be divided into four layers: the hardware, the operating system, application software, and database. These components are not necessarily distinct entities but rather represent a set of functions that are combined in different ways depending on the particular configuration. At times, one or more of these layers may be shared by two or more systems; for example, many commercial applications use an embedded operating system (OS) such as VxWorks as part of their overall design.
ICS Communications and Protocols
ICS communications are based on industrial protocols. Industrial protocol is a standard used to communicate between different systems or components. Most of these protocols are based on open standards, which means that anyone can use them as long as they follow the protocol rules. The most common industrial communication protocols include Modbus and DNP3.
Configuring ICS Devices for Security
The principle of least privilege is a foundational concept in security, particularly when it comes to industrial control systems (ICS). The principle states that users should only have the privileges they need to perform their job functions and no more. This can be tricky in an ICS environment because different machines often require different privileges at different times. However, configuring these machines with this ideal in mind will ensure that your organisation's resources are protected from malicious users as much as possible.
For example, consider an operator who needs access to both the user interface of an industrial control system and its high-level configuration functions so they can adjust parameters on demand. If you configure this user with all the necessary access privileges for both tasks instead of just one or the other, then you're increasing their potential for success but also increasing their chances for failure if something goes haywire—and something always does go haywire eventually!
The industrial control systems (ICS) used in the US are a critical part of many major industries, including power generation and transmission, oil and gas refining, manufacturing operations, transportation systems, and water and wastewater treatment. The operating characteristics of these systems make them particularly susceptible to cyberattacks that could cause physical damage or result in loss of life.
The ICS community has long been aware of this problem; however, there has been little progress toward implementing security measures. In fact, recent research shows that most ICS devices still have no form of authentication or encryption enabled by default when they come out of their boxes. This lackadaisical attitude is dangerous because it makes these devices easy targets for attackers looking to launch damaging attacks on critical infrastructure systems.
Conclusion
The industrial control systems market is growing rapidly. This means that more organisations are adopting ICSes to achieve their business goals, and with them comes a greater need for security. While there are many options available today, it’s important to remember that not all security solutions are created equal; some products may be better suited than others, depending on your specific requirements (and budget). We hope this comprehensive analysis of the most common threats facing these devices has given you some insight into how best to protect yourself from potential attackers!

OPTIMISM – Operational Perseverance Twin for Integration of Mechanisms and Instruments Sent to Mars (2020), Jet Propulsion Laboratory (JPL), Pasadena, CA. This Vehicle System Test Bed (VSTB) is the Earth-side counterpart of the Perseverance rover that landed on Mars in 2021. The last photo shows OPTIMISM nose-to-nose with MAGGIE (foreground) at the JPL Mars Yard, where they simulate how the hardware and software will perform before they transmit commands to Mars. It's particularly useful for testing software patches before sending updates to Perseverance. Don't worry though – it's not running Windows, but the VxWorks Real-Time Operating System (RTOS). "The Mars 2020 Perseverance test bed team's motto is 'No optimism allowed'. So we named the test rover OPTIMISM to remind us of the work we have to do to fully test the system. Our job is to find problems, not just hope activities will work. As we work through the issues with OPTIMISM, we gain confidence in Perseverance's capabilities and confidence in our ability to operate on Mars." – Matt Stumbo, VSTB lead.

Decades Old Code Is Putting Millions of Critical Devices Under Threat
Armis, the enterprise security firm, got a puzzling call from a hospital that uses the company’s security monitoring platform. A few weeks earlier, the researchers had found that one of its infusion pumps contained a kind of networking vulnerability. But that susceptibility had been found in an operational system called VxWorks — which the infusion pump didn’t run.
