The twoĭigilent PMOD-compatible connectors will be used to connect to the LED To hold the RGB pixel values to be displayed on the panel. We’ll use two of the block RAMs as frame buffers The FPGA board contains a Xilinx Spartan 6 LX9 FPGA. Or a USB power adapter or use a separate +5VDC, 2.1mm I.D., You can either use a USB cable to power the board from your computer You’ll need a BeagleBone Black CPU board and a +5VDC power supply for Is driven at 1/16 th duty cycle and must be continuously refreshed to display an image.īeagleBone Black CPU board w/ USB or +5VDC power supply TheĬolumns are driven using multiple sets of shift registers and the rowsĪre driven, two rows at a time, using a 4-bit address decoder. This panel contains 1024 RGB LEDs arranged in a 32x32 matrix. The following hardware items are required: RGB LED panel with a random twinkling pattern connected to the LogiBone FPGA board and some other sample panel images. The complexity of this project lies mostly in theĪ demonstration of the project is available on YouTube.Ī demonstration of the project expanded to six panels is also available on YouTube.įigure 1. The hardware for this project is relativelyĮasy to construct-just 16 data signals connect the LED panel to the Panel to a BeagleBone Black board using the Xilinx Spartan 6 LX9 FPGA on In this project, we interface a SparkFun or Adafruit 32x32 RGB LED 7 Running the Panel Using the Stock Bit File.6 Downloading and Compiling the Software.
