= Segemented displays and LEDs =

Common types of segmented displays are

*7 segment displays (many also include a decimal point, therefore they can contain 8 LEDs) 
*alphanumeric (can display numbers 0-9 and letters A-Z)
**these are sometimes called 'starburst' segment displays 
**number of segments depending on type, eg 16 plus decimal dot (Kingbright PSA/PSC 08) 
*dot matrix, eg 5x7 dots (Kingbright TA/TC 07) 
*bargraph, several different types available. (eg. Kingbright DC-10 with 10 LEDS)

Electrically, there are two types of segmented displays:

*common cathode (CC) 
*common anode (CA)

When you buy displays, you'll always see either CC or CA. Most displays can be bought in both variants.

Common cathode type displays seem to be more commonly used than the common anode type. This fact is often mirrored in the prices: CC is usually a bit cheaper than CA.

PHCC can control both types. See below for boards for CC and for CA.

Seven Segment Displays are commonly used in homecockpits in various places:

*MCP/Autopilot for heading, altitude, vertical speed and airspeed/mach 
*radio tuning panels 
*ADF radio 
*INS/IRS on some types 
*fuel qty on some types
