CMX-Tiny+? for dsPIC30F Devices
In some cases, well-structured linear programming is
sufficient for a product. In most cases, however,
programmers appreciate not having to worry about
structuring their code to perform all necessary tasks in
a timely manner. This is where CMX-Tiny+ can help.
CMX-Tiny+ allows tasks (pieces of code that do
specific duties) to run quasi-concurrently. This means
that tasks will seem to run all at the same time – doing
many specific jobs simultaneously.
In addition, CMX-Tiny+ has been especially designed
to offer such a small Flash/RAM footprint that it can be
used with only the on-board Flash/RAM of the dsPIC
DSC as a single chip solution. Based upon a scaled
down version of the popular CMX-RTX?, CMX-Tiny+
retains most of the power of CMX-RTX, as well as the
more frequently used functions.
Features
CMX-Tiny+ takes the worry and headaches out of
real-time programming. The software lets the
embedded programmer concentrate on the overall
application while taking care of the little details.
Finish projects faster and more efficiently with
CMX-Tiny+.
Some RTOS software offers only cooperative
scheduling, which means that the running task has to
call the scheduler to perform a task switch. Others
offer time slicing in which each task runs for a certain
period of time, at which point, a task switch takes
place no matter what. Others claim to be fully

CMX-Tiny+ allows a task of higher priority that is able
to run (whether starting or resuming) to preempt the

lower priority running task. This will cause the
scheduler to save the context of the running (lower
priority) task and restore the context of the higher
priority task so that it is now running.
A truly preemptive RTOS allows interrupts to cause an
immediate task switch. This means that the interrupts
now have the added ability of using the RTOS’s
functions.
