AWR1843: AWR1843 to Raspberry Pi Connection

Request for Information on mmWave SDK and SPI Master/Slave Code for the AWR1843BOOST

Dear Cesar,

I am writing to request some additional information and guidance on working with the mmWave SDK and specifically, the SPI Master/Slave code that is available. I have been working on a project that involves connecting the AWR1843BOOST radar sensor board to a Raspberry Pi 4 using SPI communication.

I understand that TI has provided a modified version of the mmWave SDK demo that uses SPI instead of UART to communicate with the host. I am hoping to get some guidance on how to get started with this modified demo and how to modify the code to work with my specific setup. For example, where do I run it ? What program can I use to run the code ? Is it the code composer ? Do I run the master code on the raspberry Pi ? If so do I have to get the code composer on the Pi ? 

Additionally, I would greatly appreciate any information you can provide on the SPI slave and master code. Specifically, I would like to know how the code works, how to modify it for my specific setup, and any best practices or tips for working with SPI communication.

Thank you for your time and assistance with this matter. I look forward to hearing back from you soon.

Regards,

Adil
