Hi,

I have a small problem with Visual Micro - or I may do something wrong.

So far all went really fine. I use Visual Micro and the debugger since a while and it is of great help.

With my new robot I use encoders. Just for testing I output the encoder counter values in the main loop.

Important code:

//declarations
volatile unsigned long encRight = 0;
volatile unsigned long encLeft = 0;

//Setup
pinMode(2, INPUT_PULLUP); attachInterrupt(0, encLeftInterrupt, CHANGE);
pinMode(3, INPUT_PULLUP); attachInterrupt(1, encRightInterrupt, CHANGE);

//Loop
Serial.print(encRight);
Serial.print("-");
Serial.println(encLeft);

//Interruput functions
void encRightInterrupt() {
	encRight = encRight+1;
}

void encLeftInterrupt() {
	encLeft = encLeft+1;
} 

When I compile and upload my sketch with the Arduino GUI, I see the counter for the interrupts raise in the serial output.
When I compile it with Visual Micro the values stay 0.

May it be that the volatile declaration is ignored by the compiler?

I'll give it a try this weekend.

Thanks for the update. 

Things to watch out for, if sharing the serial port with the debugger. 

Do not  put breakpoints on your own manual serial statements. 

Do try to limit your own serial to a reasonable rate. It can overflow the arduino serial buffer and cause confusing displays.

If you are using the debugger, where possible use breakpoint messages instead of manual serial.print messages. Normally this consumes less memory because vm does not store the debug strings on the arduino chip, it also simplifies the serial output and leads to less problems.

Best of luck
