Effective C Tip #9 - Use #warning ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Back in 1999, my fellow embedded guru Nigel Jones wrote an article for Embedded Systems Programming magazine concerning the #error preprocessor directive. While the #error directive has remained one of his favorite tools for effective C programming, he has become an equally big fan of #warning.
The use of #warning is simple enough. After showing how to use it, Nigel explains how and why he uses #warning to protect incomplete code and comment out code. |

Embedded Software Forensic Analysis ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
It's said that medical charts are written by doctors but only ever really read by lawyers. The same is sometimes true of the artifacts of our embedded software development and testing processes. To understand the perspective of the lawyers and experts who may someday review your code in a legal proceeding, read my latest blog post about best practices for firmware expert witnesses.

What's the State of Your Cortex? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Recently, Miro Samek was involved in a fascinating bug hunt related to a very peculiar behavior of the ARM Cortex-M3 processor. Given the incredible popularity of this core, he decided to blog about what he learned by digging deep into the mysteries of ARM Cortex and its RTOS-supporting features.
