In the latest Lesson #10 of my Embedded C Programming with ARM Cortex-M Video Course I explain what stack overflow is and I show what can
The insanely popular ARM Cortex-M processor offers very versatile interrupt priority management, but unfortunately, the multiple priority numbering conventions used in managing the interrupt priorities
When developing embedded code for devices with non-trivial user interfaces, it often pays off to build a prototype (virtual prototype) of the embedded system of
As part of my New Year’s resolution for 2013, I just started to teach an Embedded C Programming Course with ARM Cortex-M on YouTube. The
Christmas is right around the corner and if you wonder about the presents, I have just an idea for you. No, it is not the
On the free support forum for the QP state machine frameworks, an engineer has recently asked a question “superloop vs event dispatching“, which I quote
The demise of the ESD Magazine marks the end of an era. In his recent post “Trends in Embedded Software Design“, the magazine insider Michael
With UML, just as with anything else in the embedded space, the ultimate criterion for success is the return on investment (ROI). Sure there are
Much ink has been spilled on the Next Big Thing in software development. One of these things has always been “automatic code generation” from high-level
If you haven’t put your hands on the recent James Grenning’s book “Test-Driven Development for Embedded C” yet, I highly recommend you do. Here is
For a number of years I’ve been getting questions regarding protothreads and comparisons to state machines. Here is what I think: Protothreads in a Nutshell
Recently I’ve been involved in a discussion on the LinkedIn Real-Time Embedded Engineering group, which I started with the question “Is an RTOS really the
Arduino (see arduino.cc) is an open-source electronics prototyping platform, designed to make digital electronics more accessible to non-specialists in multidisciplinary projects. Arduino has gained popularity,
The traditional fully 2-dimensional structure of UML state diagrams is too much rope to hang yourself with. There is no standard drawing order or pattern; some designers
Today I wanted to let you know about a new, free, graphical tool called QM (QP-Modeler) for drawing state machines and generating production-quality embedded code.
In my previous post, “RTOS Considered Harmful”, I have identified blocking as the main cause of the particular brittleness and inflexibility of the programs based
I have to confess that I’ve been experiencing a severe writer’s block lately. It’s not that I’m short of subjects to talk about, but I’m
In my previous post “A Heap of Problems” I have compiled a list of problems the free store (heap) can cause in real-time embedded (RTE)
Some design problems never seem to go away. You think that anybody who has been in the embedded software development business for a while must
If I were to search my soul, I’d have to admit that the use of assertions has helped me more than any other single technique,
