====== Expert Tab ======

This tab contains more advanced parameters for adjusting various Pixy things. To bring up the Expert Tab, first bring up the Configure Dialog (click on the gear icon or select **File➜Configure**). Now select the **Expert** tab under **Pixy Parameters**.

  * **Color code multiplier:** The signatures associated with color codes can be more inclusive, because false positives are less likely. Also, the color swatches used with color codes may be somewhat reflective, which requires a more inclusive signature. The **Color code multiplier** is multiplied by the corresponding **Signature range** (in the [[wiki:v2:Signature_Tuning_Pane|Signature Tuning Tab]]) to create the signature range for the color code.

  * **Color code mode:** This parameter sets the behavior of color codes, including enabling/disabling. Hovering the mouse over the parameter will provide information on the available settings.\\
**Enabled:** Color codes are enabled, normal mode.\\
**Disabled:** Color codes are disabled.\\
**Color codes only:** Only color codes are reported. Objects that match non-color-code signatures will not be reported.\\
**Mixed:** This is the same as normal color code mode, but Pixy will also report color-code signatures that aren't part of color codes. (Normally, Pixy only reports color-code signatures that are part of color codes -- 2 or more color-code signatures that are close together.)

  * **Signature teach threshold:** This parameter applies when you are teaching Pixy a signature using the button-push method. It allows you to adjust how inclusive Pixy is when determining which pixels are part of the object you are trying to teach. You can find more information [[wiki:v2:Some_Tips_on_Generating_Color_Signatures_2|here]].

The short video below shows the teach threshold in action:

  * **LED brightness:** sets the brightness of Pixy's RGB LED. Pixy's LED is quite bright if you want it to be (too bright to look at!)

  * **Startup program:** This parameter sets the program that gets executed upon power-up. The available programs are listed in the pulldown menu.

  * **Debug:** sets the debug level within Pixy. Setting the value to 0 means that no debugging information is displayed.
