Digital signal processing (DSP) provides developers with the ability to clean-up and analyze complex signals in a flexible and cost-efficient manner all from software. When developers typically think about DSP, they often picture expensive, dedicated processors, but modern microcontrollers, such as the Arm Cortex-M processors, now include DSP extensions that allow DSP algorithms to be … Continue reading 5 Tips for Getting Started with Digital Signal Processing (DSP) on Arm Cortex®-M CPUs

The Hardware Abstraction Layer Design Process
Using a HAL is a great way to develop software that can be easily reused and ported from one application and platform to the next. Why would a developer want to do such a thing? For starters, reinventing the wheel over and over again gets pretty boring. I believe most developers want to be working … Continue reading The Hardware Abstraction Layer Design Process
7 Tips for using assertions in C
One of the greatest bug squashing tools available to embedded software developers is the assert macro. Despite the power of assert, I rarely see it implemented and in the cases where it is used the implementation is either flawed or incorrect. The following seven tips should help elucidate not only when and where to use … Continue reading 7 Tips for using assertions in C

One of the biggest, and least spoken about issues that I have encountered is that developers are writing their software for success. Writing for success sounds great, except that what I mean is that developers are writing their software assuming that … Continue reading The Biggest Embedded Software Issue Is …
