12.6.3 CMX-SCHEDULER™
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
microcontrollers. 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™. 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 devices.
Key features of the CMX-Scheduler include:
• FREE for use on any dsPIC device
• Easy to learn and use
• Truly preemptive kernel
• Supports up to five tasks
• Fast performance
• Free bug fixes and updates
• No royalties on shipped products
• Compatible with CMX-Tiny+ and CMX-RTX
• Complete electronic documentation
• Integrated with CMX-MicroNet for optional
networking connectivity
12.7 TCP/IP Stack (CMX-Micronet™)
CMX-Micronet is an embedded TCP/IP stack that is
specifically designed for optimized use of Flash and
RAM resources on dsPIC30F devices. The software
runs directly on the dsPIC30F with no gateways or PCs
required. The stack can be run in Stand-Alone mode or
work in conjunction with an RTOS. Using only industry
standard protocols, CMX-MicroNet offers true TCP/IP
networking via Direct, Dial Up or Ethernet connectivity
and Wireless Ethernet (802.11b) as well.
Up to 127 sockets can be open at a time. They can be
ethernet sockets and/or either PPP or SLIP sockets.
PPP and SLIP cannot be used at the same time. An
HTTP Web server, FTP server, SMTP client and DHCP
client are also available. The RS-232 link, if used, can
either be a direct cable link or through a modem.
Key features of CMX-MicroNet include:
• Tested and proven with hundreds of design wins
around the world
• Extremely small Flash/RAM requirements
• Software solution does not require additional
processor
• Web pages may contain CGI calls and Server
Side Includes
• FTP files, including new firmware
• Send e-mail
• Can serve up Java applets
• No proprietary protocols
• Runs stand-alone or with any RTOS
• Economical one-time fee
• Full source code provided
• No royalties on shipped products
• Excellent documentation and support
