TIDA-010022: TIDA-010022 Sensor Node: Connect IWR1642BOOST and LAUNCHXL-CC1352R1 via SPI interface

Part Number: TIDA-010022
Other Parts Discussed in Thread: LAUNCHXL-CC1352R1, , IWR1642BOOST, IWR1642

Hello,

I'm exploring the possibility to connect IWR1642BOOST and LAUNCHXL-CC1352R1 (Sensor Node) through SPI interface instead of UART and reproduce the tests from TIDA-010022.

In this case, I have three questions:

1) Are there any hardware modifications on the IWR1642BOOST to connect both boards using SPI?

2) Other than code changes to the MSS project in the CCS to accomodate SPI communication, do you know about any other code changes needed?

3) Is there any similar Reference Design to evaluate the SPI communication code for the IWR1642?

Thank you very much!

    You will need the HW modifications outlined in TIDA-010022 except for the following:

    - the MSS_LOGGER modification, since this pin is not needed as data will come from SPI

    - the SPI signal modifications, since you want to keep the SPI signals connected

    You'll need to enable the SPI driver in the CC1352 code.  Check the SPI master example code in the TI Resource Explorer here for reference.

    I'm not aware of any that interfaces a CC radio with the IWR1642 in SPI mode.
