The Colin Walls Blog
Embedded software and stuff that interests me ...

  • Video about selecting an embedded operating system
    My latest video blog is now available. This time I am looking at operating systems for embedded applications and how you go about selecting one. You can see the video here or here: Future video blogs will continue to look at topics of interest to embedded software developers. Suggestions for topics are always welcome via […]

  • I am entertained
    I am not very good at doing nothing. I do not mean that I work all the time. I need relaxation, but the term means different things to different people. Some years ago, we were on vacation and I spent a large part of the day exploring along the coast. I posted a screenshot from […]

  • Instruction set simulation
    I enjoy hearing about other people’s lives and, hence, often read biographies. Just lately I have been reading about Bill Gates. Interestingly, he and I have many similarities in terms of interests and approach. However, he is, of course, a billionaire and I am not. In lots of ways the book is more about Microsoft […]

  • 12 Things for 2020
    New Year greetings! There are many people who are heralding a new decade as well, though it may be argued that the decade does not start until 2021, but I will save my pedantry for another day. 🙂 I recently reported on the reasonable success that I had with goals [if that is what they […]

    My latest video blog is now available. This time I am looking at file systems for embedded applications. You can see the video here or here: Future video blogs will continue to look at topics of interest to embedded software developers. Suggestions for topics are always welcome via comment, email or social networking.

  • 12 things done or not
    At the beginning of the year, I wrote about my 12 Things for 2019. This was a list of a dozen goals [kind of] that I wanted to achieve in the course of the year. I reported on progress here and here. This, my last blog post of 2019, seems the obvious place to report […]

  • MISRA C anniversary
    I have always liked the C language. Initially the appeal was its power and the possibility to write very succinct code. My early experiences with the language [at which time I was often involved in tech support] quickly taught me that writing readable and maintainable code was a necessity, as the language can quickly lead […]

  • A bit “off color”
    I am interested in communication. This is a very important part of my work: writing and speaking in order to clearly explain ideas. People tell me that I do a reasonable job, which is pleasing, as I do my best. However, I am limited by really speaking just one language – actually, I often joke […]

  • Always learning
    All my life I have taken a delight in learning stuff. I do not mean that I particularly like many hours of intensive study – learning does not need to be that hard. To learn, you just need to be inquisitive and not shy about asking questions. How does that work? Why is that like […]

  • Why not use bit fields for device registers?
    A topic that I have touched upon before [here and here] is bit fields in C. They are facility in the C language that should probably be retired. They were designed to perform a single function, which is almost obsolete and irrelevant to modern software. However, they are also mistakenly used for an alternative application […]
