Hello,

I am working on occupancy detection demo in Automotive toolbox.

https://dev.ti.com/tirex/explore/node?node=ANjPbaVnjUyzRAuPlBpY0g__AocYeEd__LATEST

Please I need the steps of how to change number of zones from the firmware.

I don't need any recommendations for other examples.

My steps was:

1- zoneDef 10 7 10 1 14 7 10 33 14 20 10 2 11 20 10 13 11 20 10 25 11 20 10 36 11 47 10 2 11 47 10 13 11 9 10 8 32 24 10 8 32

2- add 2 columns for each coeffMatrixRow

3- add 2 columns for each rowNoise

4- change ODDEMO_MAX_ZONES to 10

5- change ODDEMO_MATRIX_ROW_SIZE to 6

Is that correct?

Thanks,

Hi,

This demo will not support the number of zones you are interested in.

The demo is optimized for the number of zones mentioned in the documentation.

thank you

Hello Cesar,

what's is the maximum capabilities regarding number of zones in this demo. Can this demo accept 16 zones?

Hello,

Does implementation of feature extraction and zone decision algorithms on Heatmap inside Matlab work?

I will try it for the default number of zones (8 zones) first then I will expand it to 16 zones later.

Thanks,

Mostafa

Hello

Seems like the question here is similar to your previous post. in which we provided an example of other labs/demos that can let your configure custom zones.

The question about device vs matlab seems to be highlighted as being on the device. The data format is another way to identify what the device sends out (decision etc).

Thank you,

Vaibhav

Hello

I repeat the same question many times because I don't get any answer related to my questions!!

Thanks,

HI, Mostafa:

The procedure to modify the zone and retrain the coefficients is explained at:

C:\ti\mmwave_automotive_toolbox_3_3_0\labs\incabinsensing\front_mount_occupancy\docs\VOD_coeff_training_steps.pdf

As Cesar mentioned, the code won't work for your 16 zones. It is designed to support only two zone or 4 zones as explained in the above documents. But you can always based on this demo, and develop your own demo. But we will not be able to support you.

Best,

Zigang
