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 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:
- DE-DP14112 3mm 5v, xopr's version (not available anymore)
- DE-DP14211 5mm 5v
- DE-DP14116 3mm 12v, newer version (verified by Krilek, thanks)
The project also uses a modified version of wildstray's ht1632c library which you can find here on github.
current implementation
- The attached power supply is too weak to have all the leds lit at full brightness. Expect crashing hardware here
- The display has a jumper which allows 3 modes at boot, and 3 modes at run time; the mode is determined by first reading the jumper setting on boot, and then run-time

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.
