    Are these some high power blue LEDs? High current and high Vf? Is that the reason you need one pin for each LED? Please tell me what I'm missing :-)

    Yes, I'm using high brightness blue leds (fwd voltage 3.2V, my PSU is 4V) in parallel drawing about 20mA, therefore two = 40ma...too much for one PIC pin...hence wanting to treat two pins as one virtual pin in code. But it's no big deal....thought I'd ask - and as ever there is something that exists that can be brought into play, except that I need to control the pin on/off via TRISC to avoid clicking so I can't personally use it.
