Wireless Evaluation Module Interface

Included in the communication peripherals are the headers that support the CC-EM boards from TI. The

transceiver modules connect to the USCI of the MSP430F5529 configured in SPI mode using the UCB0

peripheral. Libraries that interface the MSP430 to these transceivers are available at www.ti.com/msp430

under the Code Examples tab. The RF PWR jumper must be populated to provide power to the EM

daughterboard. The following radio daughter cards are compatible with the MSP-EXP430F5529

Experimenter Board:

•

CC1100EMK/CC1101EMK

– Sub-1-GHz radio

•

CC2500EMK

– 2.4-GHz radio

•

CC2420EMK/CC2430EMK

– 2.4-GHz 802.15.4 [SoC] radio

•

CC2520EMK/CC2530EMK

– 2.4-GHz 802.15.4 [SoC] radio

•

CC2520 + CC2591 EM (if R4 and R8 0-

Ω resistors are connected)

NOTE:

Future evaluation boards may also be compatible with the header connections.

4.4.4

eZ430-RF2500T Interface

The eZ430-RF2500T module can be attached to the MSP-EXP430F5529 Experimenter Board in one of

two ways

– through an 18-pin connector (J12 – eZ RF) or a 6-pin connector (J13 – eZ RF Target). The

pins on the eZ430-RF2500T headers are multiplexed with the pins on the CC-EM headers, which allows

the EZ430-RF2500T module to behave identically to a CC-EM daughterboard. Power must be provided to

the EZ430-RF2500T module by setting the jumper RF PWR (JP14). The eZ430-RF2500T connection

should always be made with the antenna facing off of the board. For more information on the connections

to the required eZ430-RF2500T, see the eZ430-RF2500 Development Tool User's Guide (SLAU227),

available through www.ti.com/ez430.
