IWRL6432AOPEVM: Request for configuration of mmWave Demo that supports Building Occupancy Detection example

Thiam Chi Gan said:

• Is this example using mmWave Demo firmware on IWR6843AOP?

Yes

Thiam Chi Gan said:

• Can IWRL6432AOP perform the object tracking similar to this example? by installing overhead or wall mount? If not, what is the limitation for IWRL6432AOP?

IWRL6432 can do the same, but the visualizer code will need to be modified to support the new TLV encoding for the IWRL6432. Wall mount will perform best for both 6843 and 6432, but overhead mount will still work. IWR6843 will perform better than the IWRL6432 because it has a wider field of view and more precise angular resolution because it has more antennas. You may also need to tune the configuration file for the tracker to run overhead for the IWRL6432, as that is not featured by default.

1. from "overhead_occupancy_counter_gui", in "pc_6843_3d_aop_overhead_3m_radial_low_bandwidth.cfg", how did the parameters compRangeBiasAndRxChanPhase found?

This is board-dependent. Please reset them to the default values. This bug was corrected in later versions of the toolbox. Use what I have below:

compRangeBiasAndRxChanPhase 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0

Best,

Hi,

This is not something we offer online. This document describes the process.

In a few lines, I was able to generate the following for the chirping parameters. You will need to fill in the rest of the lines.

Proposed IWRL6432 config:

chirpComnCfg 25 0 0 128 4 70 2
chirpTimingCfg 60 10 0 55 60
channelCfg 7 3 0
frameCfg 2 0 400 64 100 0
factoryCalibCfg 1 0 30 0 0
