IWR1443: SPI with MSP430F5502

James Atwell

Part Number: IWR1443
Other Parts Discussed in Thread: MSP430F5502, , TIDEP-0091

I'm using an MSP430F5502 to get data from an IWR1443 using SPI.  The MSP is the master and the IWR is the slave.  The slave initiates all of the data transfers by setting a pin on the MSP430 to indicate that data is ready.  The MSP430 interrupt routine for that pin then starts and reads the data with a transaction as master, using startSpiReadAsync().

I also want to initiate writes from the MSP to send configuration information to the IWR. Do you have an example of this?  What is the correct SPI function to use?

Thanks!

    Hi James,

    I would recommend looking at the TIDEP-0091, it interfaces the IWR1443BOOST board with an MSP432 Launchpad. Several hardware modifications are required but the software files will be of use to you, they are available near the bottom of the TIDEP-0091 page.

    The design uses the SPI driver to interface the two devices.

    If you have more questions on the SPI driver for IWR1443, please open up a new thread with part number IWR1443 and we can have our periphery expert look into this.

    For queries on the MSP side then I would recommend opening up a new thread with the MSP430 part number.

    Cheers,
