The concepts and techniques in this chapter apply to other RTOSes as well, but different operating systems use different APIs to carry out the techniques. In the next chapter, we will run through the same examples using the popular Linux operating system.
Introduction
We have decided to use two operating systems for the examples of operating system use—eCos and Linux. Why did we choose these two? Both are open source, royalty-free, feature-rich, and growing in popularity. Learning how to program using them will probably enhance your ability to be productive with embedded systems.
