Wiring for 4 digit 7 Segment LED Display

[gggwww]

Hello,

Looks like this Macro is configured as a 4 digit Common Anode multiplexed display.

Im using a 16F887

Should the Anode lines be driven through an NPN transistor - say with a 1K Ohm as Base resistor ?- this would mean that a logic 1 on the base of the NPN 's from the 16F887 would drive the Anodes high. For a Segment to be lit is the Flowcode logic for the Macro driving the segments to ground to enable them - so high on the anode and low on the segment that's supposed to be on.

Can you confirm

Thanks
