AWR1243: LVDS streaming and capture with python

Part Number: AWR1243
Other Parts Discussed in Thread: IWR6843, , MMWAVE-STUDIO, DCA1000EVM

Hi,

a customer is using a package with a python script for the Host side and an application that is pre-built for an IWR6843 EVM, which is called xwr68xx_lvds_stream_mss.xer4f . This is not directly released inside of an SDK, but works nicely to get raw data out to a PC and capture with python. 

I can share if needed the exact package.

However the customer needs to replicate this for an AWR1243 and ultimately for a 2-chip cascade solution with AWR1243.

Is there a build configuration for this lvds_stream application that can work for an AWR1243?

Can this work for a cascade solution?

Or will a cascade solution need to be configured with mmWave Studio, or say an example application out of the DFP package?

If there is a build configuration for the AWR1243, what images are being created, aka MSS and radarSS images.

Thanks,

--Gunter

    Hi Gunter,
    To configure AWR1243 you need to use either DFP example application or mmwave-Studio where it loads the patch/firmware and send all the configurations over SPI (using FTDI dll/lib) to AWR1243 (even to configure the LVDS streaming) and then using DCA1000EVM (connected with AWR1243) you can capture the LVDS data.
    Ask your customer to refer mmwavelink_example (DFP) which can be ported with Python as well to control/configure AWR1243.

    Above explained option is applicable for single chip AWR1243 device.

    Hi Jitendra,

    we are taking a close look at the DFP mmwavelink_example project for the PC. 

    If a customer has custom HW for a 2 chip cascade AWR1243 system, do we have another version of the mmwavelink_example that can load firmware into both AWR1243 chips and capture from both into the DCA1000 EVM?

    Hi Gunter,
    Currently, we don't have a reference application for Cascade AWR devices.
