Update： I have designed a new single board for this, and all test OK See wiki for details https://github.com/xfce/hdmilight-v2/wiki ================================================ For latest version, go to http://hacks.esar.org.uk/ How to use: 1) Manufacture the HDMI receiver board that can be found in the 'board' directory (CADSoft Eagle format). 2) Open the 'fpga/hdmilight.xise' project in Xilinx ISE and generate a bit file. 3) Edit the files under the config directory to configure the LEDs. 4) Edit 'Makefile' in the top level directory and set the DATA2MEM path for the Xilinx data2mem tool location on your system. 5) Run 'make' in the top level directory, which will build 'tools/makemem', then the firmware image, then the config files, before merging the firmware and config into the final bitfile. The final result should be hdmilight.bit in the top level directory. 6) Upload hdmilight.bit to a Papilio Pro FPGA board 7) Install the HDMI receiver board on to the Papilio board. 8) Connect LED strips to output pins 9) Open a serial terminal to the Papilio 10) Connect HDMI source to receiver board 11) It should now be working.
