Summary

Add a browser-based live preview and camera tuning example for the
Arducam Pivariety IMX230 camera on T3 Gemstone O1.

The example provides:

  • Live browser preview
  • Exposure control
  • Analogue gain control
  • Focus control
  • Software automatic exposure
  • Contrast-based autofocus
  • White-balance adjustment
  • Gamma, contrast and saturation controls
  • Snapshot capture
  • Persistent runtime settings

Hardware

  • Board: T3 Gemstone O1
  • Camera: Arducam B0324/Pivariety IMX230, UC-788 Rev.B
  • Interface: CSI0/J11
  • CSI configuration: 2-lane MIPI CSI-2
  • Kernel: 6.12.24-ti

Portability

The example does not contain timestamped or board-specific build paths.

Runtime locations can be configured through environment variables:

  • IMX230_GST_PLUGIN_DIR
  • IMX230_TIOVX_LIB_DIR
  • IMX230_DCC_DIR
  • IMX230_MEDIA_DEVICE
  • IMX230_VIDEO_DEVICE
  • IMX230_SENSOR_DEVICE
  • IMX230_SETTINGS_FILE
  • IMX230_SNAPSHOT_DIR
  • IMX230_HOST
  • IMX230_PORT
  • IMX230_PYTHON

The default DCC location is:

/opt/imaging/imx230/linear

Add a browser-based live preview and camera tuning example for the Arducam Pivariety IMX230 camera on T3 Gemstone O1.

The example supports exposure, analogue gain, focus, white-balance adjustment, automatic exposure, autofocus and snapshots.

Use environment variables for custom GStreamer, TIOVX, DCC and device paths so the example does not depend on local build directories.
