DK-EM2-2500S Datasheet, PDF (1/3 Pages) Texas Instruments – 2.4 GHz SimpliciTI™ Protocol on Stellaris®

2.4 GHz SimpliciTI™ Protocol on
Stellaris®
The Stellaris® 2.4 GHz SimpliciTI™ Wireless Kit
(DK-EM2-2500S) from Texas Instruments provides a
low-power RF network solution for customers’ end
equipment. The solution combines TI’s easy-to-use
SimpliciTI™ protocol with the new Stellaris EM2 expansion
board and the Chipcon CC2500EM 2.4 GHz evaluation
module along with the full suite of tools an engineer needs
to develop and prototype 2.4 GHz wireless embedded
applications with Stellaris. The DK-EM2-2500S wireless kit
works with our most popular Stellaris microcontroller
development kit, the DK-LM3S9B96 (sold separately).
SimpliciTI’s open-source software is aimed at simple, small
RF networks and was designed for easy implementation on
several TI RF platforms. Such networks typically contain a
limited number of battery-operated devices which require
long battery life, low data rate, and low duty cycle that talk
either directly to each other or through optional access
points and range extenders. The minimal resource
requirements for a SimpliciTI™ implementation make it a
perfect low-cost solution for wireless communication.
The Stellaris® SimpliciTI™ solution allows software
application developers to become familiar with the
operation of the CC2500EMK using their Texas
Instruments’ Stellaris embedded microcontroller platform
without having to be concerned about the RF portion of the
system. The Stellaris EM2 expansion board facilitates the
connection of up to two wireless expansion modules using
SPI as the primary interface to the DK-EM2-2500S module.
