CMX-Scheduler™ for dsPIC
CMX-Scheduler is the result of a special collaboration
between CMX and Microchip. Available in object code
only, CMX-Scheduler is available for FREE to
embedded systems designers using the dsPIC
signal controllers. CMX-Scheduler is specially
designed for developers whose designs do not require
a full blown RTOS and/or who are wondering if a kernel
might help their application. The perfect entry-level
kernel, CMX-Scheduler is intuitive to use and easy to
implement.
CMX-Scheduler offers many growth paths for future
designs. User applications developed with the
CMX-Scheduler kernel are upwardly compatible with
the popular CMX-Tiny+™ or CMX-RTX™ RTOSes.
CMX-Scheduler also is tightly integrated with the
unique CMX-MicroNet™ TCP/IP stack for those
applications that require networking connectivity.
CMX-Scheduler software and documentation is
delivered in electronic format and is freely licensed for
unlimited product usage on the dsPIC DSC devices.
