I have the 'paid' version of visual micro with the very cool debugging utilities, but I'm having some trouble with the digital pin state display when working with my Arduino Uno sketch using Visual Studio 2008.

In my setup() function, I set pins 1, 3, and 5 to inputs, and everything else to output.  When I run my sketch using the Virtronics simulator, the digital pins are shown as being set up correctly.  However, when I run the same sketch with Visual Micro with my Uno attached, the digital readout shows 7, 13, and 15 as inputs (I'm assuming here that 'red' is an output, and 'green' is an input).

Any idea why this is happening?

The setup code:

    //Set OUTPUT pins to drive the left wheel motor
    pinMode(LeftMotorSpeedPin,OUTPUT);
    pinMode(LeftMotorDirPin1,OUTPUT);
    pinMode(LeftMotorDirPin2,OUTPUT);

    //Set OUTPUT pins to drive the right wheel motor
    pinMode(RightMotorSpeedPin,OUTPUT);
    pinMode(RightMotorDirPin1,OUTPUT);
    pinMode(RightMotorDirPin2,OUTPUT);

    //Setup forward HC-SRS04 ultrasonic sensor
    pinMode(FrontSensorTrigPin,OUTPUT);
    pinMode(FrontSensorEchoPin,INPUT);

    //Setup forward HC-SRS04 ultrasonic sensor
    pinMode(LeftSensorTrigPin,OUTPUT);
    pinMode(LeftSensorEchoPin,INPUT);

    //Setup forward HC-SRS04 ultrasonic sensor
    pinMode(RightSensorTrigPin,OUTPUT);
    pinMode(RightSensorEchoPin,INPUT);

    //get initial distance readings
    prevfrontdistval = GetDistanceCm(FrontSensorTrigPin, FrontSensorEchoPin);
    prevleftdistval = GetDistanceCm(LeftSensorTrigPin, LeftSensorEchoPin);
    prevrightdistval = GetDistanceCm(RightSensorTrigPin, RightSensorEchoPin);

I have attached two images; one from Virtronics showing its idea of the digital I/O setup, one from the Visual Micro debugger.  both were obtained using the exact same sketch.

Any clues would be appreciated.

Thanks for the quick response - and yes, it does explain what I'm seeing.

I would like to add my vote to the idea of providing I/O as well as LOW/HI visualization.  As I'm sure you are aware, Virtronics does this by physically separating the I/O designations (colored text - red for OUTPUT, green for INPUT) from the LOW/HI designations (white dot for low, red dot for HI) and this is very intuitive.   

Come to think of it, this may be what got me in trouble with your display, as I expected something similar
