Using more than one Arduino pin as LED output

[lesthegrngo]

If I want to drive two different LEDs as a particular warning light, can I assign an LED output to more than one pin?

Yes, you have to declare the pins as output in the setup routine and than just set it High or Low as usual.

I'd have thought you could just assign two LED code lines to different pins and alter the name slightly.

Why don't use the advanced code and talk to more than one output?

Because this is simpler:

DcsBios::LED masterCautionA(0x1012, 0x0800, 2);
DcsBios::LED masterCautionB(0x1012, 0x0800, 3);

than this:

//  In setup routine:
pinMode(2, OUTPUT);
pinMode(3, OUTPUT);

 

void onMasterCautionChange(unsigned int newValue) {
    digitalWrite(2,newValue);
    digitalWrite(3,newValue);
}
DcsBios::IntegerBuffer masterCautionBuffer(0x1012, 0x0800, 11, onMasterCautionChange);

Thanks guys, so different ways to do it. It won't be many instances, so even the longer version would be OK, so it's nice to know the ways
