# Arducam Pivariety IMX230 Tuner

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

## Hardware

- T3 Gemstone O1
- Arducam B0324/Pivariety IMX230, UC-788 Rev.B
- CSI0/J11
- 2-lane MIPI CSI-2

## Required software support

This example requires:

- Arducam Pivariety Linux V4L2 driver
- T3 Gemstone O1 IMX230 Device Tree overlay
- IMX230 support in `edgeai-tiovx-modules`
- IMX230 support in `edgeai-gst-plugins`
- Matching IMX230 DCC files

The default DCC directory is:

```text
/opt/imaging/imx230/linear
```

The following files are expected:

```text
dcc_viss.bin
dcc_2a.bin
```

DCC binaries are not included in this example.

## Python environment

Create a virtual environment with access to the system GObject,
OpenCV and NumPy packages:

```bash
python3 -m venv --system-site-packages venv
venv/bin/pip install -r requirements.txt
```

System packages such as Python GObject bindings, OpenCV, NumPy,
GStreamer, `media-ctl` and `v4l2-ctl` must already be installed.

## Run

```bash
./run.sh
```

Then open:

```text
http://BOARD_IP:8000
```

## Custom build directories

Custom GStreamer and TIOVX builds can be selected without editing the
source code:

```bash
IMX230_GST_PLUGIN_DIR=/path/to/gst/plugins \
IMX230_TIOVX_LIB_DIR=/path/to/tiovx/lib \
IMX230_DCC_DIR=/path/to/imx230/dcc \
./run.sh
```

## Optional environment variables

- `IMX230_DCC_DIR`
- `IMX230_GST_PLUGIN_DIR`
- `IMX230_TIOVX_LIB_DIR`
- `IMX230_MEDIA_DEVICE`
- `IMX230_VIDEO_DEVICE`
- `IMX230_SENSOR_DEVICE`
- `IMX230_SETTINGS_FILE`
- `IMX230_SNAPSHOT_DIR`
- `IMX230_HOST`
- `IMX230_PORT`
- `IMX230_PYTHON`
- `IMX230_GST_REGISTRY`
- `T3_EDGEAI_ENV`

Runtime settings, snapshots, virtual environments, DCC binaries and
compiled libraries are intentionally excluded from the repository.
