CC2520EMK: Connecting MSP432 to smartRF05EB with CC2520EMK

Part Number: CC2520EMK
Other Parts Discussed in Thread: CC2500EMK, CC2520, MSP430F5438A

Hi,

I am a bit confused about how to map GPIO pins of the CC2520EMK to the headers on smartRF05 (V 1.8). I want to know the configuration for P18 and P20 when CC2520EMK is connected. I did find other threads which are about reading ADC of the CC2500EMK but is it the same for CC2520EMK?

Can anybody direct me to any threads related to connecting a separate microcontroller like MSP430 or MSP432  to smartRF05? I just want to learn the basics.

Thanks,

BEZAK

    Bezak,

    I am not sure I follow your question, but let me give you some inputs.

    The CC2520 is a transceiver, it does not contain any processing element and therefore it needs some device to provide it with commands.

    The smartRF05 contains a connectivity interface that lets you connect the CC2520 to a PC application called SmartRF Studio, but not much else.

    If you want to start developing code on an MSP430 that then controls the CC2520, I will recommend the TRXEB platform (it has a MSP430F5438A) and the headers are designed to match the CC2520 connector.

    Regards,

    Hi Bezak,

    I split your thread so the MSP team can answer your MSP432 questions.

    Thanks,

    Hi,

    I have looked at the example you recommended to me. I still do not understand what I need to write in my SPI message on the microcontroller (to the CC2520) to fully define the frequency of the transmission and the message content, and how to receive the data on the microcontroller back from the CC2520. I have the CC2520 datasheet, but it's quite bewildering to know where to start; I have read the "SPI" and "Instruction Set" chapters, but I feel a simple(r) example would really help my understanding.

    I own an MSP432 microcontroller, and a pair of CC2520 transceivers, and two SmartRF05 boards. I am using Code Composer Studio (CCS) to program the microcontroller.

    I have experience communicating using the SPI on the MSP432 with a thermocouple module. I am aware of how to use the interface on the microcontroller, but not on the transceiver.

    In short, I need to know the format of my message (SI/SO) to define a message for the transmitter to transmit, and to pull any received data from the receiver.

    Thank you for your help,

    Bezak.
