AWR1642BOOST: Reading from serial

Rakshit Ramesh

Part Number: AWR1642BOOST

Hi,
I'm really surprised at how efficiently the mmwaveDemo visualizer is able to gather UART data for Range Azimuth plot. There is very little latency, frame drops, etc.
I've tried fetching the data and plotting it on matlab and python but i can't seem to get that speed.
I've tried asynchronously reading it, buffering the frames, etc.
I wlll be making a switch over to SPI if any further attempts fail.

I'd love to hear of suggestions.

Thanks

Hi Rakshit,

This has been a known issue which is why the mmWave demos have gone from Matlab Gui's to TI's Gui Composer. I understand you'd like to use MATLAB for your application but you will not achieve the speed that you are looking while using the serial UART connection.

The transition to SPI is a very clever idea and definitely worth pursuing but I cannot confirm that you will achieve the results you are looking for.

Let me know if you have some questions that are more specific.

Cheers,
Akash

I wanted to know if the cloud visualizer uses UART over the XDC emulator, or something of the sort. What is the serial client that the cloud agent use written in?

Hi Rakshit,

Yes it is done over UART.

Cheers,
