Introduction
The XC-3 LED Tile Control Kit is an ideal starting point for prototyping LED scan
board designs using XMOS XCore processors. It provides a complete software
programmable solution for controlling LED arrays and strings.
The XC-3 LED Tile Control Kit includes:
· XC-3 Development Board
· XTAG Connector that provides a JTAG interface between the board and XMOS
Tools
· USB Cable to connect the XTAG to your development system
· External 5V power supply
Further information on the XC-3 is available from the XMOS web site. Download the
hardware manual, schematics and design files from: www.xmos.com/xc3.

Getting Started
The XC-3 board includes an implementation of the XMOS LED Reference Design
software which provides native support for the MBI5026 and MBI5030 Macroblock
LED Driver IC. The application is designed to interface to an SMD-32X16-1R1G1G-F-P6,
a 32x16 pixel LED module using 12 x MBI5026 or MBI5030 on a 1/8 scan rate with a
16-way 2mm IDC connection. The reference design software is pre-loaded on the
XC-3. The latest version is available from: www.xmos.com

Driving LEDs with the XC-3 Board
The LED application can be used out-of-the-box as a demonstration. A PC can be
directly connected to the Ethernet daisychain, and a standard video player, such as
the open-source mplayer application, can be used to broadcast video

For large video wall systems a separate distribution or tiling unit is required, which
inputs DVI, HDMI or VGA video at HD resolutions, separates the data for each of the
tiles in the system, packetizes it and distributes over one or more gigabit Ethernet
streams.

Configuring a single board demonstration
The following instructions provide details on how to confi gure the software supplied
with the XC-3 board when connected to a single SMD-32X16-1R1G1G-F-P6 LED module
using MBI5030 drivers. Please refer to the LED Reference Kit Application Note for
information on using MBI5026 drivers:
1. Plug-in the XC-3 using the 5V power supply.
The PLL LED on the bottom of the board lights up to indicate that the board
has been powered up.
2. Connect the XC-3 board to the LED module.
The text "XMOS" is displayed.
3. Set the PC to use a static Ethernet IP address, with an IP of 192.168.0.1, and a
subnet mask of 255.255.0.0.
4. Connect the PC to the XC-3 using an Ethernet cable (not supplied in kit).
5. Test connectivity by pinging the default IP address of the XC-3: 192.168.0.254.
6. Use the mplayer application, supplied with the LED Reference Design software,
to stream video to the tiles, with the following command:
m p l a y e r - vf s c a l e = 1 6 : 3 2 - l o o p 0 - vo x u d p : n o i n i t :
t i l e w i d t h = 1 6 : t i l e h e i g h t =32 v i d e o f i l e . avi

Configuring a dual board demonstration
1. Follow Step 1 and Step 2 from the single-board demonstration.
2. Run the LED Tile Confi guration Application with the following command:
l e d c o n f i g . exe - - p r e f i x = 1 9 2 . 1 6 8 - - p o r t = 3 0 6
3. In the application, run the command:
ac
The application acknowledges this with "Autoconfigure packets sent" message.
4. Quit the application by typing:
q u i t
The IP addresses for the LED modules are automatically configured.
5. Test connectivity with both tiles by pinging 192.168.1.1 and192.168.1.2.
6. Use the mplayer application, supplied with the LED Reference Design software,
to stream video to the tiles, with the following command:
m p l a y e r - vf s c a l e = 3 2 : 3 2 - l o o p 0 - vo x u d p :
