AWR6843: LVDS Streaming without processing

Prabu Kadakkarai Vel

Part Number: AWR6843

I need an example where i can use the controller for just lvds data streaming and no further processing which works with the AWR6843.

It would be nice to have the project file so we can build it and use it to verify results.

P:S.I dont use an EVM board.

Since you state that you don't have an EVM board I am going to assume that you have a custom board. Is this correct?

Also I am going to assume that you want to stream out raw ADC data from the radar sensor. Is this correct?

When you say that you want a project file can you be more specific with regards to what you want to do?

Best regards,

1. Yes a cutom board.

2. We use a data capture card dca100 to stream adc data through ethernet to PC.

3. I want a project which lets me configure the AWR6843 in a minimalistic way. When i set the modulation through CLI commands, it should send out the adc data. I will have a project and will be able to build a bin file, flash it on AWR6843 and stream data through the capture card.

I beleive there should be an example which does this simple funtionality already. I cannot locate this though.

Here are some resources with regards to the closest thing that we currently have pertaining to what you are asking.

1. Studio CLI User Guide:

https://dev.ti.com/tirex/explore/node?node=AK3GYIhDPkgp.R8qt-gVUg__Z2F8GEn__LATEST

2. ADC Data Format is the same as in section 6 of the following document:

https://www.ti.com/lit/an/swra581b/swra581b.pdf

There is only support for ADC raw data transfer without header: lvdsStreamCfg -1 0 1 0

This information should enable you to create a script which will parse that ADC data once it is captured.
