💻 3 Strategies for Handling Errors in Embedded Software
It is very tempting to assume that a system will behave as perfectly in the field as it does on the engineering bench. During development, embedded software is written under the best of conditions.
The developer knows how the system is supposed to work and development usually proceeds smoothly. However, as thousands of devices start to get into the hands of users, the chances that the unexpected will happen becomes statistically more probable. In today’s post, let’s explore the strategies that developers need to write software that can handle unexpected errors.
The way that a developer approaches writing their software is what determines whether their system will recover from errors gracefully or whether it will blowup metaphorically in the user’s face. The key is having the right development attitude that considers what can go wrong and implementing the recovery mechanism while the software is being written.

💻 Green VS Brown Programming Languages
Interesting article about latest tendencies in software development and popularity of programming languages in particular.
The Stack Overflow Developer Survey results are a great source of information about how developers work. The survey results have rankings for The Most Dreaded Programming Languages and The Most Loved Programming Languages.
▫️ The TOP 15 Loved Programming Languages: Rust, TypeScript, Python, Kotlin, Go, Julia, Dart, C#, Swift, JavaScript, SQL, Shell, HTML, Scala, and Haskell.
▫️ The TOP 15 Dreaded Programming Languages: VBA, Objective-C, Perl, Assembly, C, PHP, Ruby, C++, Java, R, Haskell, Scala, HTML, Shell, and SQL.
Joel Spolsky: The reason that (developers) think the old code is a mess is because of a cardinal, fundamental law of programming: It’s harder to read code than to write it.

💻 3 Ways to Improve Your Software Development Environment
Leverage a unit test harness
Over the last several years, software development process tools have made huge leaps forward to the point where even the smallest embedded software teams can benefit from using the tools. Test harnesses provide developers with the ability to perform automated regression testing to ensure that the code is working as expected and that no new additions interact with existing code.
Spend less time debugging
According to any number of surveys, and conference talks, the average developer spends about 40 percent of their time debugging. Recovering debug time can benefit by reducing project costs, helping teams deliver on time, reduce stress, and a myriad of other benefits.
Review and improve your processes
The key to sustained success is to have a balanced approach that allows for repeatability but maintains the development team’s flexibility and adaptability.

💻 CanoPy
Canopy is a visualization tool for plotting CAN bus message payloads
A basic PC CAN interface simply dumps the bus’s message traffic into the terminal, while more sophisticated tools organize messages by the address of their intended recipients. Both of these approaches digitally lift the hood and let you examine what your car is thinking, but the wall-of-numbers approach makes finding the patterns that hold the keys to reverse engineering difficult.
Automatically plotting the data with CanoPy makes finding correlations much easier, after which the text-based tools can be used to focus in on a few specific addresses.

🚀 Exploring the SpaceX software
The actual work of software development by vehicle engineers is largely done using C++, which has been the mainstay of the company’s code since its early days. The software reads text-based configuration files. “We invented simple domain specific languages to express those things, such that other engineers in the company who are not software engineers can maybe configure it.”
Flight software for rockets at SpaceX is structured around the concept of a control cycle. “You read all of your inputs: sensors that we read in through an ADC, packets from the network, data from an IMU, updates from a star tracker or guidance sensor, commands from the ground,” explains Gerding. “You do some processing of those to determine your state, like where you are in the world or the status of the life support system. That determines your outputs – you write those, wait until the next tick of the clock, and then do the whole thing over again.”

🚀 How SpaceX lands Starship (optimal trajectory)
As part of a personal push to learn more about non-linear control, I have been playing around with a pretty powerful method known as trajectory optimization. Once the base code is set up, it’s fairly easy to go apply to various systems.
While waiting for Starship SN15 to launch (it was in fact scrubbed, sad), I decided to pull together an estimate for some of it’s dynamics and see if I could get my toy 2D simulation to perform that epic flip and land itself.
To my excitement, after some finessing, it worked quite well. But what really surprised me was when I played the output side by side with actual landing footage: it lined up very very well.
To me, this means one of two things: either I got incredibly lucky, or SpaceX is running a very similar optimization on their actual system. I think both are true.

💻 Embedded GUI implementation with Knowcode
GUI implementation is really time consuming. Sometimes it takes longer than the embedded system project itself.
That’s why a group of engineers is creating a technology called KnowCode, which aims to automate GUI implementation based on artificial intelligence technologies.
They are building a software development tool to help embedded engineers speed up GUI implementation through computer vision which automates the time consuming and dull stuff.
The purpose of KnowCode is not to replace drag-and-drop tools, because engineers will always need this kind of tool to fine tune the GUI elements and add events or transitions. The main purpose is to automate the dull task of adding and positioning every element.

💻 Useful Tips For Learning Embedded Programming
Good article for beginning in embedded programming with clean explanations, examples with pieces of code, etc.
The list is oriented to programmers like the girl/guy writing their very first lines of code up to experienced programmers from other remote galaxies like web developers. It may be useful to you if you are starting to develop for embedded systems, that go from the simplest Arduino board up to custom boards.
Most of the topics in the list are about the area I cover, that is, the microcontroller/bare-metal area of embedded programming (no high level languages or operating systems), a little on microelectronics and some other non-programming topics worth mentioning.

📥 Embox - configurable operating system for embedded systems
Embox main idea is using Linux software everywhere including MCUs.
Imagine, you need a single application in the embedded system, but you want to use some libraries (Qt, OpenCV, etc). In the Linux case, you need high-performance hardware. In Embox case you can use the software as bare-metal including the only required system parts.
In other words, Embox is util which allows creating a special distributive for your exact purpose. Although there are kernel, network, file system, standard POSIX library etc. you can accurately configure every module. Therefore it will include only those parts that you wish.
Embox allows you to:
▫️ use low power hardware
▫️ use boards with small resources
▫️ use existing software
▫️ develop your software on Linux
▫️ care less about security because static linking disables executing external software
