  • Hello Jiahui.

    I wasn't able to replicate your issue with the people counting visualizer and your configuration settings.  However, I found another bug in your profileCfg where you ended up having too many adc samples as it has to be below 256.  In addition, when the ramp end time is reduced to below 66, I was able to get it working with the people counting visualizer.

    Sincerely,

    Santosh
