IWR6843ISK: 100m CFG file in Long Range People Detection Lab

JINHYEONG LEE

Part Number: IWR6843ISK

According to this link, traffic monitoring matlab GUI and the 100m LRPD cfg file was incompatible when 4 month ago.

and It was said to be fixed with the next release.

But, in Industrial tool box 4.6.0, I still can't run 100m LRPD cfg with same problem.

How can I run the traffic monitoring matlab GUI with the 100m LRPD cfg file?

Hello,

There are two small changes needed to the file 'calculateChirpParams.m' to make the gui compatible with the 100m profile.

Modify line 61 to remove the indexing on 'P':

"calc_P(i).excessTime = P.profileCfg.rampEndTime(i)-calc_P(i).adcSamplingTime_usec -P.profileCfg.adcStartTime;"

Modify line 116 to include indexing on 'calc_P':

"calc_P(i).radarCubeSz_KB = bytesPerSample * calc_P(i).numADCSamples * numChirps * numLoops * calc_P(i).numRXChannel/1024;"

This should allow the use of multi profile chirps like the 100m cfg. Let me know if there are any issues.

Regards,

Jackson
