3216 Bicolor LED 3mm Dot Matrix Display

synopsis

xopr bought two 32x16 bicolor 3mm dot matrix displays (located in the slackspace running Conway's game of life) The display is driven by Holtek HT1632C IC's and controlled by an Arduino nano.

Here is the link to the Store's item (DE-DP14116)

current implementation

The display has a jumper which allows 3 modes at boot, and 3 modes at run time.

The attached power supply is too weak to have all the leds lit at full brightness. Expect crashing hardware here

Some of the modes (in random order

• display test (led flood)
• display test (noise)
• display test (unknown)
• game of life (slow)
• game of life (normal)
• game of life (fast)
• terminal emulator
• animating space invaders
• season's greetings

old implementation

One of the first electronic devices on the very first day of our physical space, is the display showing ACKspace with a different prefix scrolling in vertically.

Since the video plugin still doesn't work with MOV, here a direct link. You see a christmas LED tree with the marquee on the background here: Media:Christmas_tree_and_message_ticker.mov.
