µC/OS-III is fairly easy to use once it is understood exactly which source files are needed to make up a µC/OS-III-based application. This chapter will discuss the modules available for µC/OS-III and how everything fits together.
The figure below shows the µC/OS-III architecture and its relationship with hardware. Of course, in addition to the timer and interrupt controller, hardware would most likely contain such other devices as Universal Asynchronous Receiver Transmitters (UARTs), Analog to Digital Converters (ADCs), Ethernet controller(s) and more.
This chapter assumes development on a Windows®-based platform and makes references to typical Windows-type directory structures (also called Folder). However, since µC/OS-III is provided in source form, it can also be used on Unix, Linux or other development platforms.
