\Software

This sub-directory contains all software components and projects.

\uCOS-III

The main µC/OS-III directory.

\Ports

The location of port files for the CPU architecture(s) to be used.

\<architecture>

The files in this directory contain the µC/OS-III port, see Porting uC-OS-III for details on the contents of these files.

os_cpu.h contains a macro declaration for OS_TASK_SW(), as well as the function prototypes for at least the following functions: OSCtxSw(), OSIntCtxSw() and OSStartHighRdy().

os_cpu_a.asm contains the assembly language functions to implement at least the following functions: OSCtxSw(), OSIntCtxSw() and OSStartHighRdy().

os_cpu_c.c contains the C code for the port specific hook functions and code to initialize the stack frame for a task when the task is created.
