# Configure P10 Matrix Panels

In this example, the setup consists of 8 P10 panels (4H x 2 W) driven via a Beagle Black Bone (BBB) with an octoscroller running the Falcon Player (referred to as the FPBBB). This process should be the same for Raspberry Pi's running FPP with a Pi Hat or Colorlight Card.

First Add a New Output to the Setup Tab. It is recommended to use a DDP Output Type for FPP based P10/P5 panels. An E131 Output Type can also be used but for this guide DDP was selected.

Set the IP Address of the FPPBB(192.168.5.200 in this example). The Id is a unique controller ID for xLights to use, this Id must be different for each out. The default Id of 64001 is okay for this example. The number of channels is the total number of channels for the P10 matrix. To calculate this number channels, multiple the number of channels per LED(3 in most cases) by the number of LEDs per panel(512 for P10's) and then multiple that result by the number of Panels(eight in this example). The final values is the total channel for the Matrix.

$Channels Per LED * LED Per Panel * NumberOfPanel = Channel Count$

For this example, the total number of channels is: 3 x 512 x 8 = 12288 channels.

Set the Description Field To 'P10Matrix' and set the Controller Type to 'FPP PiHat'. The Description is important later, do not skip this step.

Click Ok and the new DDP output should be added to your Setup Tab. Click 'Save Setup' when complete.

Next, Define a model ‘P10Matrix’ for in the Layout Tab

First Select the 'Matrix' model icon in the Model Toolbar.

Click the Left Mouse Button Down then Drag the Pointer to the Right, and Release.

Next, define the model settings. Set the model name to ‘P10Matrix’ (or any name of your choice) set it as a horizontal matrix.

Set ‘# Strings’ = 64 (corresponds to number of rows), ‘Nodes/String’ as 64 (corresponds to the columns) and ‘Strands /String’ = 1. 'Starting Location' = Top Left.

A single 32 * 16 P10 panel has 16 rows (height) and 32 columns (width). Right click on the image in your Layout and select Node Layout to view the node definition.

To set the Start Channel Click the Ellipsis(three periods) button in the Start Channel Box.

Set the start Channel by Clicking the 'Controller' Option and selecting the Controller Description set earlier, from the drop-down list. Keep the 'Start Channel' set to 1.

The start channel should be set to '!P10Matrix:1' and xLights will automatically calculate the end channel.

Click the 'Save' Button when done.

Switch back to the Setup Tab. In the Setup tab right click on the 'DDP' output for the FPPBB and select 'Upload To Controller' -> 'Output - FPP PiHat'. This will automatically set the Panel Start channel In FPP for you.

## BBB FPP definition

Open The Beaglebone controller web page by entering the IP address in your web browser of choose or by right-clicking on the DDP output and selecting 'Open Controller'.

Set the FPP controller to bridge mode for testing for now. When running your show you can use bridge mode or switch to FPP Remote Mode, both will work with the DDP setup. No channel inputs need to be setup the DDP protocol handle that for you.

Click the 'Input/Output Setup' Menu Banner and Select the 'Channel Outputs' Option

On the LED Panel page, Check the Enable LED Panel Output Option. The panel layout is 2 x 4. The Start channel should automatically been updated by the Upload To Controller Option used earlier. Make sure this matches the model definition in xLights. 'Single Panel Size' sets the Panel Size and Scan Rate. For most indoor P10 panels this is '32x16 1/8 Scan'. The channel count is automatically is calculated. This should also match the model in xLights. The 'Model Start Corner' should be the same as the 'Starting Location' in xLights. 'Default Panel Color Order' should match the panel vendors recommendation. Different vendors use different Color Orders. You may have to do try all the options to find the correct one. 'Brightness' is the Panel brightness, 10 is 100%, 1 is 10%. All the other options keep to the defaults.

The vertical arrows correspond to the Up/Down physical setting of the arrows on the panel backside. The LED Panel Layout orientation is as if viewed from the front of the panels. 'O-1', 'O-2', 'O-3', etc are the outputs ports on the Octoscroller. 'P-1', 'P-2', 'P-3', etc. is the panel order for each output. The first panel connected to the Octoscroller output is 'P-1', the second panel is 'P-2' and so forth.
