    LED pixels PIC24FJ64GA004 Dynamic Tile Display

    The tiles are based on 2” square 8×8 LED displays. Each pixel in the display has a red and green LED. The LEDs are arranged in a matrix, with the red and green LEDs sharing a common cathode tied to the columns of the matrix, and individual connections for the red and green along the rows of the matrix. The matrix has 24 connections (8 columns, 8 red rows & 8 green rows).

    Underneath each display, a PIC24FJ64GA004 MCU drives the LEDs. This MCU has 35 I/O pins, 24 are used for directly driving the display. Since the MCU can’t quite sink enough current if all of the LEDs in a column are on, the column lines are connected through a ULN2803 Darlington transistor array to provide the necessary current drive.
