How to use / enable SPI Interface instead of RS232- UART interface for IWR6843 through MMWAVEBOOST and MMWAVEPOEEVM to increase the data rate from 900kbps to 10Mbps .

Any guidance/ doc reference will be useful

thanks

HI Ravi,

I would start by reviewing the TI design linked below. It is for IWR1443 but the SPI implementation is similar
www.ti.com/.../tidud26a.pdf

Also review the post linked below
e2e.ti.com/.../2858497

After setting up and initializing the SPI you need to replace the UART writes to MSS logger with a SPI transaction instead.

Thanks Charles .

Seems there is a missing link for the pdf file referred above .

The post and the code ( 2nd reference) has references to QSPI ( flash) and some pinMuxes for MibaSpi.

Not sure how to make use of the information.

Are there any reference docs to interface MMWAVEPOEEVM with MMWAVEBOOST and IWR* combination - user guide ? That would give an overall picture and help make some progress using this board.

thanks

Thanks Charles

I forgot to mention that I went through this doc earlier and couldn't make any progress bringing up the board.

Software references in the doc is in section 6.1 - given below :

------------------------------------------------

6.1 Software, Development Tools, and Example Codes To enable quick development of an end application on the R4F core in the IWR1443, TI provides a software development kit (SDK) that includes demo codes, software drivers, an emulation package for debug, and so on. The SDK is available at mmwave-sdk. Binary files for MMWAVEPOEEVM can be found here, TIDM-1018.

----------------------------------------------'

The binary file references in TIDM-1018 leads to SDKs of Simplelink etc ....

I downloaded and installed this SDK (msp432e4_sdk_2_40_00_11) and not sure which binary file to use ..

A more detailed references in the user guide for MMWAVEPOEEZVM - to interface with the sensor and get it

configured may be helpful. If someone could walk through this process with me , I'm willing to upgrade the user guide

for the benefit of the user community.

Foer example . a binary that sets the pin muxes properly to make use of the SPI interface could save us a bit of time.

This will help others who don't have prior experience working with various software stack of SimpleLInk,

and right away concentrate on streaming in radar data at higher frame rates.

thanks

A binary file with SPI interface enabled will be useful.

HI,

At the moment we do not provide any binary for the MMWAVEPOEEVM, the user is responsible for writing the code for their application.
The MSP432 SDK contains SPI, UART and other examples, SPI implementation for the IWR device has also been referenced in previous post.

Please let me know if you need help with any specific issues.

Charles O
