fyi - nifty project from Glen Akins for those that are fans of blinky pixels:
Expanding the BeagleBone Black and FPGA to Drive 6 (or more) Panels
After completing my first BeagleBone Black + FPGA project and tutorial where I drove a single 32×32 RGB LED matrix, I decided it was time to go bigger. The result is the project shown below—a 3 x 2 matrix of 32×32 RGB LED panels. That’s 6,144 RGB LEDs or 18,432 LED chips—each of which can be controlled with 12-bit color at a refresh rate of 200Hz. Let’s take a closer look at the steps required to move from driving one panel to driving six panels.
He also has a great tutorial:
In this project, we interface a SparkFun or Adafruit 32x32 RGB LED panel to a BeagleBone Black board using the Xilinx Spartan 6 LX9 FPGA on the LogiBone FPGA board. The hardware for this project is relatively easy to construct—just 16 data signals connect the LED panel to the LogiBone FPGA board. The complexity of this project lies mostly in the RTL and software.
