DOA_7seg (Rev.1)

Jumper selectable to either

  • common cathode
  • common anode

Along with the Jumper selection via JP1, the suitable driver chip has to be used for IC4 and IC5.

Features

  • select common cathode or anode via JP1 and IC4/IC5
  • 32 displays per board or 256 LEDs or any combination
  • small boardsize: 80x100mm or 1/2 Euro size.
  • dimming possible
  • no ghosting
  • hi current displays supported (25mA max. per segment)
  • all segments individually controllable
    • ie. the dot
    • allows you to create certain characters, like a capital 'A' or 'C', a lower case 'd',...
    • individual segments fully controllable by host software
  • of course, instead of 7segment displays you can also use LEDs (8 LEDs instead of one display, 16 instead of two,...)
  • controlled via the PHCC DOA bus with the AP2P Protocol.
    • multiple display controllers can be connected to the DOA bus...
    • along with other DOA bus devices (up to 256 devices currently)
