3 Tips for Validating Sensor and Communication Data in Embedded Systems

Software engineers have a bad habit of being very optimistic. This optimism often doesn’t just include their calculation on how long it will take for a specific task to be completed but also on potential failure modes for their system. If it works on the bench, the assumption is that it will also work in … Continue reading 3 Tips for Validating Sensor and Communication Data in Embedded Systems

7 Steps to Create a Reusable Debounce Algorithm

A quick google search reveals that there are over 212,000 websites that examine how to debounce a button.  After examining a number of them it is obvious that these implementations are not meant for reuse.  The implementations and strategies often lack scalability, the ability to debounce multiple buttons easily and portability.  They are tightly coupled … Continue reading 7 Steps to Create a Reusable Debounce Algorithm

Creating an SWD Adapter for STM32 Development Boards (Part 3)

My adapter boards have arrived! As we discussed in the first two parts, the on-board debugger that comes with most development boards is functional but often offers far less than a professional debugger. We’ve been exploring how we can create an adapter board for the ST Microelectronic development boards that will allow us to use … Continue reading Creating an SWD Adapter for STM32 Development Boards (Part 3)

7 Tips for Selecting a Secure Microcontroller

Developing a secure, connected device that can also operate efficiently requires that developers select a microcontroller that includes specific hardware and software features. These features can range from true random number generators through secure libraries. Let’s examine several tips for the hardware and software that developers should consider having in their secure microcontroller. Tip #1 … Continue reading 7 Tips for Selecting a Secure Microcontroller
