Embedded Software Blog

28 Jul, 2014

Colin Walls I often need to do a bit of programming – normally C or C++. I am not generally writing a real software application, as that is not my job, but I often need to produce chunks of code to illustrate a point in an article, presentation or blog post. This code can be anything from a single line to a few dozen. Obviously, all I need to do is create a text file for the code and build it using a suitable … Read More

Colin Walls Some time ago, I wrote about my view on the future of music. In a nutshell, I was saying that live performance was what it was all about. Time has moved on and I have further thoughts on the topic. Also, over that time, e-books have become quite mainstream and I question where that technology is taking us. It seems that David Bowie has been having the same kind of thoughts … Some time ago, Mr. … Read More

Colin Walls Multicore continues to be a hot topic, as an ever-increasing number of embedded systems are designed with multiple CPUs – most commonly multiple cores on a chip. One of the challenges with understanding multicore is that the term actually covers a number of architectures and approaches to design. This is a topic that I have discussed somewhat before, but the increasing popularity of multicore … Read More

"9-1-1: How can I help you...?"

Posted by Scott Salzwedel

Scott Salzwedel   “Ah, yeah…  I’m okay, but my portable device just died.”    “Your portable device, sir?”    “Yeah, the portable medical device I use to monitor my vitals.”    “Sir, let me connect you to a software developer who knows a thing or two about power management.”         There are portable devices and then there are portable medical devices. And while the malfunction or sluggishness of your smartphone … Read More

Colin Walls As I have talked about before, I am particularly interested in programming languages, with a strong focus on embedded, of course. So, I always take a look when I see a survey that looks at what developers are using and what the trends are. When I saw that the IEEE were publishing some results, they really had my attention. However, all was not what it seems … The IEEE results may be viewed interactively … Read More

Colin Walls I have made a number of recent postings focused on C++ issues, responding to a number of questions. I have a few more planned, but I was intending to give this topic a rest for a while. However, my eye was caught by one question, which I felt had some potential: I learned that Objective C objects are not complete copies of the class object. In other words, only the data and certain static structures … Read More

C++ - yet more Questions and Answers

Posted by Colin Walls

Colin Walls I am continuing to mine the rich vein of questions from my online C++ lectures, which I started two weeks ago. I am always pleased to receive questions about any aspect of embedded software by comment, email or through social media. Another three questions to consider today … I just wondering how the compiler and linker optimize C++ code. How do we compare the this optimization in different tool … Read More

Kamran Shah Our team recently held a seminar in California that covered topics related to the development of medical devices. This included a discussion on how to navigate the FDA approval process and to to develop software that conforms to the IEC 62304 standard. One area that was brought up by Steve Robertson is the increased FDA focus on cybersecuirty. FDA Concerns with Cybersecurity The internet of things ecosystem … Read More

"I want my IoT"

Posted by Scott Salzwedel

Scott Salzwedel The common refrain, “I want my MTV” was heard nearly 30 years ago when MTV was first starting out. Back then there was a lot of excitement, anticipation, and pure enthusiasm as to what MTV might become. Fast forward to today and we have yet another cultural (and technical) movement afoot. It seems everyone is talking about the Internet of Things (IoT) and how our boring, mundane lives will be soon … Read More

C++ - more Questions and Answers

Posted by Colin Walls

Colin Walls Following on from my recent online C++ lecture series, I found that I had a lot of interesting questions from the audience, which I had limited time to answer. It seemed logical to do so here. So this is the first of a number of posts where I will address one or more of these questions. If you have any questions about embedded software [not just C++], please email me and I will do my best to answer … Read More

Colin Walls A frequent question which I am asked in person or by other means is “Where can I learn about embedded software?” Although this can come from young people looking for a career [in which case their choice of college course is probably the way forward], most such inquiries come from “normal” software engineers [i.e. folks who a used to programming desktop computers etc.] or hardware … Read More

Matt Radochonski A few weeks ago we held one of our Google+ On-Air Hangouts on Internet of Things Security.  You can view the full video using the embedded YouTube video below.  During this hangout we received some excellent questions from the audience, and one of our presenters, Felix Baum has taken the time to answer three of them. How is the transition between secure and normal carried out? What part controls that? TrustZone … Read More
