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)
The project also uses a modified version of wildstray's ht1632c library which you can find here. Currently, there is a small bug which draws the space invader bitmaps on its side.
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.
Note that the first version was driven by a myAVR kit, since Arduino wasn't that mainstream back at the time.
