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

struct vs class in C++

Posted by Colin Walls

Colin Walls Maybe I should apologize for going on about C++ yet again, but, following on from the recent online lecture series that I conducted, I learned that there is a lot of interest in the topic. I also found the experience a very fruitful source of ideas, inspiration and queries – much of this will appear here. During the lectures, I would periodically pose a question, which the attendees could answer … Read More

Colin Walls Last week I conducted a series of 5 online lectures about C++ for embedded applications. [You can still access the materials and recordings from this site.] As with any such activity, although I hope that I am imparting information and advice, I also expect to get questions and ideas back. I was not disappointed. There were many smart questions that made me think [= good!]. There were no dumb questions … Read More

Colin Walls As I continue with my current pre-occupation with C++, I decided to discuss some aspects of the language with my colleague Jonathan Roelofs, who is a development tools specialist. Like me, Jonathan is particularly interested in the tools issues that concern embedded developers. As it seems to have wide interest, I decided to explore exception handling … I have a concern about the overhead of extra … Read More

C++ Q&A

Posted by Colin Walls

Colin Walls As my interest in C++ continues, I have been soliciting questions about C++ for embedded on various social media platforms. I you have a question, please email or tweet and I will do my best to answer it. #AB10630 / gettyimages.com Here is a question that came in yesterday: How testable is C++, specifically for constructs like abstract classes, templates, exceptions? This is quite a complex question … Read More

Colin Walls As I mentioned last week, I am very much in “C++ mode” just now, mainly because I am preparing for some online classes. As a result of various social media contacts, I am getting some interesting impressions of how C++ is viewed among embedded developers. There is certainly much controversy. Some developers love it, but many are very critical. Various aspects of the language concern engineers, … Read More

Colin Walls C++ has been on my mind lately. There are many reasons why embedded developers are wary – possibly even afraid – of C++. These include code bloat, execution performance and unreliability resulting from dynamic memory allocation. They are all issues with which engineers should concern themselves, however, none of them are intrinsic problems with the C++ language, as they can all be controlled … Read More

C++ for embedded - your input needed

Posted by Colin Walls

Colin Walls A frequent topic for discussion, I have found, both here and elsewhere, is programming languages for embedded development. Every developer has their favorite and has clear ideas on what is going to happen in the future. Market research also indicates certain trends, but, curiously, many of those trends have fallen victim to the innate conservatism of embedded developers. There is a strong “if … Read More

Colin Walls Quite a while ago, I made the observation that wireless connection technologies were everywhere. Nothing has changed, of course. In fact there are even more wireless devices around and, with the advent of the Internet of Things, numbers will continue to increase drastically. The term “wireless”, to some extent, means different things to different people, but it usually boils down to a data … Read More
