Scalable: The footprint (both code and data) can be adjusted based on the requirements of the application. Adding and removing features (i.e., services) is performed at compile time through approximately 40 more than 50 #defines (see os_cfg.h). µC/OS-III also performs a number of run-time checks on arguments passed to µC/OS-III services. Specifically, µC/OS-III verifies that the user is not passing NULL pointers, not calling task level services from ISRs, that arguments are within allowable range, and options specified are valid, etc.. These checks can be disabled (at compile time) to further reduce the code footprint and improve performance. The fact that µC/OS-III is scalable allows it to be used in a wide range of applications and projects.
