    • Flash provides an inexpensive and fast storage medium for MCU-based applications, but when execution time and deterministic behavior are paramount, developers need to perform these three steps to place critical functions into RAM for an extra speed boost.

    • Exploring the latest security, IoT and artificial intelligence technologies driving innovation in embedded systems.

    • Modifying Amazon FreeRTOS demonstration code for publishing messages to Amazon Web Services to support multiple topics and messages turns out to be pretty straight forward.

    • Amazon FreeRTOS simplifies cloud integration but the documentation doesn’t provide a clear picture on what is going on. In this post, we take a peek inside Amazon FreeRTOS to see what we can expect from this Amazon Web Services offering.

    • Battery life is one of the last thing on the minds of developers rushing to complete their designs but there are a number of things they can do throughout their development cycle to properly manage devices energy consumption.

    • There are several different ways you can measure the difference. 1) If you are using an RTOS, you could use Tracealyzer, System View, etc 2) If you are running bare-metal, the tried and true toggle an I/O pin before you call the function and after. Do that for flash execution and ram and use a scope or logic analyzer to measure the difference. 3) Setup a timer to measure the execution time Thanks for the question.

    • Thanks for the comment. I also highly suspect that the code just polls instead of being event driven. I'm planning to do some follow-ups that will dig deeper into the code and hopefully provide developers with some more insights into how the application behaves and what changes might be warranted for a production intent system. Thanks for the insights!
