XC-3 LED Tile Control Kit Quick Start Guide Version 1.1 Publication Date: 2010/05/10 Copyright © 2010 XMOS Ltd. All Rights Reserved. XC-3 LED Tile Control Kit Quick Start Guide (1.1) 1 2/7 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. 2 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.

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 Ethernet 100 Mbps XC-3 XC-3 XC-3 XC-3 ! 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.

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: mplayer - vf scale =16:32 - loop 0 - vo xudp : noinit : tilewidth =16: tileheight =32 videofile . avi Ethernet 10/100 Mbps 16x32 Pixel Array XC-3 6 x SPI RJ45 www.xmos.com XMOS RJ45 XC-3 LED Tile Control Kit Quick Start Guide (1.1) 2.3 6/7 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: ledconfig . exe -- prefix =192.168 -- port =306 3. In the application, run the command: ac The application acknowledges this with “Autoconfigure packets sent” message. 4. Quit the application by typing: quit 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: mplayer - vf scale =32:32 - loop 0 - vo xudp : tilewidth =16: tileheight =32: chainstart =0 _0 : chainpoint =1 _0 videofile . avi 32x32 Pixel Array www.xmos.com 6 x SPI XC-3 XC-3 6 x SPI RJ45 XMOS RJ45 XMOS RJ45 RJ45 XC-3 LED Tile Control Kit Quick Start Guide (1.1) 3 7/7 XMOS Tools Support The XMOS tools are provide in a single platform-specific downloadable file from http://www.xmos.com/tools Instructions on installing and using the XMOS Tools can be found in the XMOS Tools User Guide http://www.xmos.com/published/xtools_en.
