Digital Pins Debug Window

Hi there,

I have just updated to the latest version of Visual Micro 1512.23.1 in VS2015.  I created a new Ardunio project in VS2015 and entered the following code int he ino file:



int ledPin = 13;                 // LED connected to digital pin 13

void setup()
{
     pinMode(ledPin, OUTPUT);      // sets the digital pin as output
}

void loop()
{
     digitalWrite(ledPin, HIGH);   // sets the LED on
     delay(1000);                  // waits for a second
     digitalWrite(ledPin, LOW);    // sets the LED off
     delay(1000);                  // waits for a second
}



In the project properties I have the following items set to true:
- Report Analogs
- Report Digitals
- Report Free Memory

When I debug and upload the debug windows show as expected, and the Digital Pins window shows with the following values:
Red: 0,1,10,13,14,15
Green: 2,3,4,5,6,7,8,9,11,12

But nothing changes.  I would expect to see pin 13 change from red to green as the pin is set to High and Low in the above code.

Why is it that this does not happen?

Regards,

Scott

Hi,

The auto report runs once each time the loop() is reached. Your example would work if you used a global to determine the state so that each iteration of the loop switch on or off but not both

It's also valid to change pins at any time so there is additional breakpoint WhenHit/expression syntax that you can use to force a refresh of the pins:-

{@ReportDigital}

Other settings are documented here:-
http://www.visualmicro.com/page/User-Guide.aspx?doc=Working-With-Breakpoints-Whe...

If you have not defined a pinMode for a pin then it will be classed as floating by the arduino and it will give different readings at different times. 13 defaults to output.
