IWR1642BOOST: IWR1642BOOST SPI struggle

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642

Hello peeps,

I would like to use the SPI of the IWR1642BOOST to connect it to another Board just to transfer the Peoplecount of the Peoplecounting Demosoftware. But right now I am struggling with this.

At first I tried to go with the SPI Documentation but there is not much Information of how to use the SPI Demosoftware.

So I tried to used the Project made by ej99 ( https://e2e.ti.com/support/sensors/f/1023/p/686601/2532025

    Hi Oliver,

    Basically you need to do two things:

    1. Check the EVM schematic found on this page to ensure that the SPI is connected to GPIO out ports.
    2. Modify the initialization funtion:
      1. Change GPIOs to be in SPI mode (see the IWR1642 datasheet to see which pins to use, these should also be enabled in the SPI test)
      2. Open and initialize the SPI driver.

    Regards,

    Justin
