How Embedded Linux is used in Spacecrafts !

George Emad

This article dives into the application of Linux in spacecraft, examining the challenges it poses and proposing potential solutions. Real-life examples will be discussed, while also addressing the drawbacks of employing Linux in safety-critical missions.

Getting Started With Zephyr: Bluetooth Low Energy

Mohammed Billoo

In this blog post, I show how to enable BLE support in a Zephyr application. First, I show the necessary configuration options in Kconfig. Then, I show how to use the Zephyr functions and macros to create a custom service and characteristic for a contrived application.

++i and i++ : what’s the difference?

Colin Walls

Although the ++ and -- operators are well known, there are facets of their operation and implementation that are less familiar to many developers.

The Asimov Protocol

Ido Gendel

While the Internet is choke-full of explanations of basic data communication protocols, very little is said about the higher levels of packing, formatting, and exchanging information in a useful and practical way. This less-charted land is still fraught with strange problems, whose solutions may be found in strange places – in this example, a very short, 60 years old Science Fiction story.

Ten Little Algorithms, Part 7: Continued Fraction Approximation

Jason Sachs

In this article we explore the use of continued fractions to approximate any particular real number, with practical applications.

How to Implement Image Processing Algorithms in FPGA Hardware

Lance Harvie

Recognized for their parallelism and reconfigurability, FPGAs prove ideal for real-time processing in medical imaging and computer vision. The step-by-step approach starts with understanding FPGA basics, emphasizing their reconfigurable nature and parallel processing. It guides users in algorithm selection based on factors like processing speed, resource utilization, and adaptability, then highlights designing modular and scalable algorithms. The process includes simulation for verification, synthesis using tools like Xilinx Vivado and Intel Quartus Prime, interfacing with image sensors, and testing on real hardware. The conclusion underscores FPGA's advantages in image processing, presenting ongoing opportunities for innovation in diverse industries.
