Learn practical and easy-to-apply software process improvements that even the smallest design teams can use to make firmware easier to code, debug and test, with a tools cost of less than $600.
On May 3, 2017, Barr Group CTO and software expert Michael Barr delivered this keynote about the safety and security of Internet of Things devices at the Embedded Systems Conference in Boston.
If you've got a lot of real-time tasks and tight deadlines, what's the best way to prioritize them? Rate Monotonic Algorithm provides the optimal technique.
In a recent DDoS attack, devices such as webcams and DVRs were used to launch an attack on domain service provider, Dyn. The enormity of this event brings to light the importance of securing all devices capable of connecting to the Internet.
The safety and security of every embedded system is dependent upon proper operation of the stack (or stacks, if there are multiple). If a stack overflow occurs, a major or minor malfunction is very likely to follow. Despite this, the stack in the majority of embedded systems is sized based on nothing more than a hunch. As well, run-time stack monitoring is too seldom used.
Too often engineers give up trying to discover the cause of infrequent anomalies--because they can't be easily reproduced in the lab--dismissing them as "user errors" or "glitches." Yet these ghosts in the machine live on. So here's a guide to the most frequent root causes of difficult-to-reproduce firmware bugs.

Whether you're using only static memory, a simple stack, or dynamic allocation on a heap, you have to proceed cautiously. Embedded programmers can't afford to ignore the risks inherent in memory utilization.
Unexpected power loss and software bugs can undermine the reliability of non-volatile data. Fortunately, there are various ways to make non-volatile data resilient to such corruption.
