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, connected to fuse group B). The display is sold by Sure electronics and is driven by Holtek HT1632C IC's and controlled by an Arduino nano. They also have written a manual

There are several versions of the 3216 bicolor display which all should work with the same library:

The project also uses a modified version of wildstray's ht1632c library which you can find here on github.

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.

Note that the first version was driven by a myAVR kit, since Arduino wasn't that mainstream back at the time.

Here you see a LED christmas tree with the marquee on the background:
