  As the power, complexity, and capabilities of embedded processors continues to grow, it is easy to forget just how much can be done with inexpensive single board computers based on 8-bit processors. When the proprietary, non-standard tools from the vendor for one such embedded computer became a major roadblock, I embarked on a project to expand my own knowledge and provide a more flexible, standards based alternative. Inspired by operating systems such as Unix, Linux, and Minix, I wrote DEBROS (the Davis Embedded Baby Real-time Operating System) [1], which is a fully pre-emptive, priority-based OS with soft real-time capabilities that provides a subset of standard Linux/Unix compatible system calls such as stdio, BSD sockets, pipes, semaphores, etc. The end result was a much more flexible, standards-based development environment which allowed me to simplify my programming model, expand diagnostic capabilities, and reduce the time spent monitoring and applying updates to the hundreds of devices in the lab currently using this hardware.[2]
