VL53L8CH More CNH Bins for One CNH

[JGarrettW]

Hello,

I am using the 53L8A1A to evaluate the VL53L8CH with the MZAI_EVK_v1.0.1 software. For my application, I need high CNH resolution for as long a histogram as possible, but for only one histogram. Because of that, I aggregated down to one row and one column with the following configuration settings.

  CNH_4x4_ONECNH:
    StartType: 0
    Resolution: 16
    RangingPeriod: 500
    ZoneMode: 2
    GlareFilter: 0
    ExtendedMode: 2
    cnhStartX: 0
    cnhStartY: 0
    cnhMergeX: 4
    cnhMergeY: 4
    cnhCols: 1
    cnhRows: 1
    cnhNumBins: 75
    cnhSubSample: 1
    isDefault: false
    isVisible: true

I see in the CNH_Data_Size sheet within the MZ-AI_Configuration Excel sheet that the MZ-AI GUI limits the cnhNumBins parameter to 75. The calculator says that the data size for more bins than that does work, however.

Is there a reason that the parameter is limited to 75 and, if not, is there an easy way for me to change that limit?

Thanks,

Garrett

I checked with the developer. 75 is a limit of the PC-based GUI. It is not a limit of the sensor. 

See if you can do your evaluation with the 75 bin limit, then switch to your board and get away from that PC-based limitation.

It will work.
