µC/OS-II is a portable, ROMable, scalable,
preemptive real-time, deterministic, multi-
tasking kernel for microprocessors, micro-
controllers and DSPs. µC/OS-II can manage
up to 63 application tasks and provides the
following services: Semaphores, Event Flags,
Mutual Exclusion Semaphores (to reduce
priority inversions), Message Mailboxes,
Message Queues, Task Management, Time
Management, Fixed Sized Memory Block
Management and more.
µC/OS-II comes with ALL the source code.
In fact, the source code is 100% portable
ANSI C and is probably the cleanest and
most consistent code of any RTOS. The
internals of µC/OS-II are described in the
book MicroC/OS-II, The Real-Time Kernel
(ISBN 1-57820-103-9) by Jean J. Labrosse.
A validation suite has been developed for
µC/OS-II and provides all the documentation
necessary to prove that µC/OS-II is suitable
for Safety Critical Systems common to Aviation
and Medical products. Although this feature
may not be applicable to your needs, it does
prove that µC/OS-II is a very robust RTOS.
You can ‘View’ the status of your tasks
which are managed by µC/OS-II with an
add-on module called µC/OS-View.
A number of popular debuggers provide
µC/OS-II kernel awareness which allows you
to display µC/OS-II’s internal data structures
in a convenient series of Windows.
