1. V4L2 sesor driver

Als we imx219 als voorbeeld nemen, staat de code in drivers/media/i2c/soc_camera/canaanchip/imx219_0.c

        {0x0157, 0x40},
        {IMX219_TABLE_END, 0x00}
    };
  • Voeg de configuratie als volgt toe aan de modusvolgorde:

    static const struct imx219_mode supported_modes[] = {
        {
            .width = 1920,
            .height = 1080,
            .max_fps = {
                .numerator = 10000,
                .denominator = 300000,
            },
            .hts_def = 0x0d94 - IMX219_EXP_LINES_MARGIN,
            .vts_def = 0x048e,
            .reg_list = imx219_init_tab_1920_1080_30fps,
        },
        {
            .width = 1080,
            .height = 1920,
            .max_fps = {
                .numerator = 10000,
                .denominator = 300000,
            },
            .hts_def = 0x0d78 - IMX219_EXP_LINES_MARGIN,
            .vts_def = 0x0898,
            .reg_list = imx219_init_tab_1080_1920_30fps,
        },
    };

    Illustreren: .width = 1080 is de effectieve pixel van het sensoruitvoerniveau. .height = 1920 is het aantal zeer geldige rijen voor de sensoruitgang. .hts_def = 0x0d78 - IMX219_EXP_LINES_MARGIN is het totale aantal pixels van het sensoruitvoerniveau minus de belichtingslijndrempel. 0x0d78 is het totale aantal pixels van het sensoruitvoerniveau, dat zal worden gebruikt in het bestand vidieo.conf. IMX219_EXP_LINES_MARGIN is om de blootstellingsrijdrempel te definiëren, die momenteel 4 is en kan worden gewijzigd. .vts_def = 0x0898 is het totale aantal regels sensoruitgangshoogte, dat wordt gebruikt in het bestand vidieo.conf. .reg_list = imx219_init_tab_1080_1920_30fps is de configuratie hierboven gewijzigd.

  • Voeg het model van stream toe, dat zal worden gebruikt imx219_s_stream

    static const struct imx219_reg start[] = {
        {0x0100, 0x01},   /* mode select streaming on */
        {IMX219_TABLE_END, 0x00}
    };
  • Voeg de stream off-modus toe, die wordt gebruikt imx219_s_stream

    static const struct imx219_reg stop[] = {
        {0x0100, 0x00}, /* mode select streaming off */
        {IMX219_TABLE_END, 0x00}
    };

    return 0;
}

1.3 Wijzig de initialisatieconfiguratie in de sondefunctie (naar imx_probe)

1.3.1 Het versienummer wijzigen

dev_info(dev, "driver version: %02x.%02x.%02x",
    (uint8_t)(DRIVER_VERSION >> 16),
    (uint8_t)(DRIVER_VERSION >> 8),
    (uint8_t)(DRIVER_VERSION));

1.3.2 Canaan information parsing toevoegen en wijzigen in DTS

    ret = of_property_read_u32(node, CANAANMODULE_CAMERA_MODULE_INDEX,
            &priv->module_index);

    ret |= of_property_read_string(node, CANAANMODULE_CAMERA_MODULE_FACING,

    ret |= of_property_read_string(node, CANAANMODULE_CAMERA_LENS_NAME,
            &priv->len_name);

1.3.3 Gewasinformatie wijzigen voor momenteel ondersteunde modi

Dit komt overeen met de bovenstaande configuratie-informatie.

priv->crop_rect.left = 680; //0x2A8
priv->crop_rect.top = 692; //0x2b4;
priv->crop_rect.width = priv->cur_mode->width;
priv->crop_rect.height = priv->cur_mode->height;

1.3.4 De sensornaam en andere informatie wijzigen

Deze sensornaam wordt gebruikt in video_cfg.conf-bestand, mediactl_lib bibliotheek deze nodig heeft om de sensor te vinden.

memset(facing, 0, sizeof(facing));
if (strcmp(priv->module_facing, "back") == 0)
    facing[0] = 'b';
else
    facing[0] = 'f';

snprintf(sd->name, sizeof(sd->name), "m%02d_%s_%s %s",
        priv->module_index, facing,
        IMX219_NAME, dev_name(sd->dev));

1.4 De sensorversie van de leesfunctie toevoegen of wijzigen (imx219_video_probe)

    if (ret < 0) {
        dev_err(&client->dev, "Failure to read Chip ID (low byte)\n");
        goto done;
    }
    chip_id |= ret;

    if (model_id != 0x0219) {
        dev_err(&client->dev, "Model ID: %x not supported!\n",
            model_id);
        ret = -ENODEV;
        goto done;

        model_id, lot_id, chip_id);
done:
    imx219_s_power(subdev, 0);
    return ret;
}

1.5 Wijzig de besturingsfunctie van de sensor

Voornamelijk de standaardblootstellingswaarde en de beginwaarde van de belichtingslijn worden gewijzigd (IMX219_ANALOGUE_GAIN_MIN/IMX219_DIGITAL_GAIN_MAX/IMX219_ANALOGUE_GAIN_DEFAULT, IMX219_DIGITAL_EXPOSURE_MIN/IMX219_DIGITAL_EXPOSURE_MAX/IMX219_ DIGITAL_EXPOSURE_DEFAULT)

[out]   dev_info:   mediactl_lib返回从video的配置文件得到的video信息,具体的解释如下。
video_used:这里是指ISP的pipeline,如果使用就会返回1,否则0。K510支持ISP_F2K/ISP_R2K这两个pipeline,每个pipeline最多支持4个video输出。
video_name[4]:返回的video的名字。f2k的四个video是video2/video3/video4/video5;r2k的四个video是 video6/video7/video8/video9
enable[4]:返回的每个video是否使能,1 -- 使能,0 -- 没有使用。
video_width[4]:返回的每个video的宽度。
video_height[4]:返回的每个video的高度。
video_out_format[4]:返回的每个video的输出图像格式,具体见《video的配置文件》的解释。
