AFE4490 Pulse Oximeter with ZigBee CC2520

Other Parts Discussed in Thread: CC2520, AFE4490

Hi,

I would really appreciate some input on this. I am currently working on my ZigBee development kit CC2520 DK for some data transmission. Now I know that the CC2520 is obsolete, but I was interested nonetheless in acquiring a Pulse Oximeter such as the AFE 4490 to experiment with physiological data transmission from one node to another. My question is wether do you know if the AFE 4490 would be compatible with the obsolete CC2520.

Thank you,

Mikael

    Hi Mikael,

    Can you provide a block diagram of your application?
    Are you looking at directly interfacing the AFE4490 to CC2520 through the SPI interface?

    Hi Praveen,

    Thanks for the feedback. Unfortunately I do not have a block diagram I am a newbie really to the kit and got it recently. I got some simple communication set up. I was assuming that I would need to communicate the AFE4490 to the ZigBee through the SPI interface, but do you think it will work? I was reading papers saying that the data needs to be transmitted to the cc2520 stack before being sent out to the other node so I was hoping I could get the pulse oximeter to communicate with the cc2520.

    Essentially I want to connect the SPO2 sensor -> ADC -> ZigBee transmitter node -> ZigBee receiver node -> Computer. Maybe I could use an Arduino to store the data before sending it off to the pc?

    Thank you, I appreciate your input.
