Auto-calibrating Display using Unconstrained Layouts of Individually-addressable LEDs

Hardware Used

• AMD Spartan-7 FPGA
• WS2812b LED strands: sequentially addressed LEDs used to display content.
• OV5640 Camera Module: used both for calibration and input data for displaying on the LED display.
• HW-221 level shifter: drives the 5V logic from the 3.3v logic of the Urbana board.
