  1. Hi, I have been working on a PMOD TFT LCD that can be used to play video directly from the FPGA using only two PMODs. I designed the hardware a couple of years ago but recently I had to do a project where I needed to use the Vivado block diagram interface. I thought it was pretty cool how fast it was to put a design together so I went about making an IP Core that controlled the PMOD. It has an AXI Lite interface used to initialize the LCD and then a AXI Stream interface that can be connected directly to a VDMA core. I ended up making three different demos including the followi

    Hi, I believe I can help with this. This board is pretty cool and in answer to your first question 'Can the card be customized with a new display?' Yes, it should but after looking at the TFTs manufacturers site http://www.tianma-europe.com, I haven't found any other display that would work with this connector, granted I only looked at 5. This reduced selection is determined by the connector chosen by the board designer and it uses a unique 45 pin FPC (Fine Pitch Connector) to communicate with the TFT. In order to see what was available I looked at two different sites for TFTs, htt
  3. I just got this up and running: http://youtu.be/dIAJrQxToCc It's a custom TFT LCD controller board using only two PMODs. The board controlling it is an FPGA devboard that communicates with the host computer using the FTDI's FT2232H in synchronous FIFO mode so that I can transfer data between the host and board at a rate of about 25MB/s using a simple protocol. I wrote a scripting tool that glues together wishbone cores to create an FPGA image using a simple configuration file. Editing configuration files are great but I thought it would be so much better if I could modify the FPGA
