I hope I am using the terminology correct.

 

I am just learning the Netduino and prgramming, and I read where you can use the following code for a button read:

 

buttonState = !button.Read():

 

and this will invert the input.  I tried using this concept on another line and VS 2012 pro is giving me an error.  I used:

 

led2 = !led1;  (failed) {error message Error 1 Operator '!' cannot be applied to operand of type 'Microsoft.SPOT.Hardware.OutputPort' c:...Blink-shieldProgram.cs 28 24 Blink-shield}

 

and

 

led2 = !led1.Read();  (failed as well) {error message Error 1 Cannot implicitly convert type 'bool' to 'Microsoft.SPOT.Hardware.OutputPort' c:...Blink-shieldProgram.cs 28 24 Blink-shield}

 

Am I trying to use this in a way not designed, or is my syntax wrong?

 

Guys, I know I am throwing a bunch of questions out here, and thank you for all of your help getting me up and going.

Since led2 is an OutputPort, you will have to write

led2.Write(!led1.Read());

led2 and led are instances of the [color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]Microsoft.SPOT.Hardware.OutputPort class; look up the public methods and properties as to what you can do with them.[/color]

That fixed it.  Thank you!

 

Now to continue playing around and see what other randomly useless code I can come up with to learn this new toy.
