Software
CMX-MicroNet™ for dsPIC30F Devices
CMX-MicroNet is an embedded TCP/IP stack that is
specifically designed for optimized use of Flash and
RAM resources on Microchip’s 16-bit Digital Signal
Controller. The software runs directly on the processor
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.
Description
CMX-MicroNet is available for a low, one-time fee with
no royalties on deployed products. In addition,
CMX-MicroNet offers only industry standard protocols
running directly on the target processor and full source
code is provided with every sale.
