The “Software for CC1100/CC2500 and MSP430 - Examples and Function Library” is the recommended starting point for developing software for the CC1100/CC2500 and MSP430 combination. The software demonstrates how to use some of the many advanced digital features and packet handling capabilities of the CC1100/CC2500. The software examples have been developed for the MSP430 Experimenter’s Board, but can easily be ported to another hardware platform.
