(1) Objects in µC/OS-III are named when they are created and these functions are not required in µC/OS-III. (2) Multipend no longer exist in µC/OS-III. (3) µC/OS-III returns an error code for this function. Initialization is successful if OS_ERR_NONE is received from OSInit(). In µC/OS-II, there is no way of detecting an error in the configuration that caused OSInit() to fail. (4) An error code is returned in µC/OS-III for this function. (5) Enable or disable µC/OS-III’s round-robin scheduling at run time, as well as change the default time quanta. (6) A task that completes its work before its time quanta expires may yield the CPU to another task at the same priority. (7) An error code is returned in µC/OS-III for this function. (8) Note the change in name for the function that computes the “capacity” of the CPU for the purpose of computing CPU usage at run-time. (9) An error code is returned in µC/OS-III for this function. |
