Top 5 Causes of Nasty Embedded Software Bugs

Finding and killing latent bugs in embedded software is a difficult business. Heroic efforts and expensive tools are often required to trace backward from an observed crash, hang, or other unplanned run-time behavior to the root cause. In the worst case scenario, the root cause damages the code or data in such a subtle way that the system still appears to work fine -or mostly fine- for some time before the malfunction.

How to Allocate Dynamic Memory Safely

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.

Every program uses random access memory (RAM), but the ways in which that memory is divided among the needy parts of the system varies widely. This article surveys the options available in hopes that the reader will be better equipped to choose an approach for a given project.

How to Protect Non-Volatile Data

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.

How to Improve Product Usability

Product usability problems require the engineer to take off his engineering hat and think more like a user.
