=== 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)
