AVR Freaks

Put a diagnostic signal on a pin that is present when it is not sleeping.

You should be able to tell from that if it is sleeping or not.

The hex file shrank considerably (46.3% usage to 29.0% usage), so that's a good sign.

What were the -O setting in "Debug" and "Release". It sounds like the Debug mught have been set to the dreaded -O0.

On a related note - what's the difference between "Build solution" and "Build Nixie Clock"? (Nixie Clock is the project name) They seem to do the same thing, unless I'm missing something. And what about "Compile"?

If you only have one project in the solution then yes they do the same thing. When you have more than one project then "Build Solution" means "Build all the projects" while "Build " just builds the one.

This is really an inheritance from VS2010 where AS6 started. In that it's not unusual to have many many projects in a solution. For example I just built something in Visual Studio that said:

========== Build: 1 succeeded, 0 failed, 52 up-to-date, 2 skipped ==========

So that's a solution with 55 projects (mainly libraries/DLLs) in it.

This is a really good argument for using version control, so you could go back and check the differences in the output files.

Not to beat up on you, but you broke an important rule by changing multiple things at once: hardware and tool chain.

I do use version control. I reverted to old code. That's why I'm pretty sure it's AVR Studio doing it.

Then have you loaded the old hex file (not a new hex file built with the old code) into your current hardware and measured the current?

int main (void)
{
    init(); //configure peripherals
	while(1)
    {
		if (CurrentMode & Mode_Battery)
		{
			//switch to power save mode
			SMCR = (1<<SM1) | (1<<SM0) | (1<<SE);
			sleep_cpu();
			
		}
    }
	return(0);
}

int main (void)
{
    init(); //configure peripherals
	while(1)
    {
		PORTC ^= 1<<PORTC0;
		if (CurrentMode & Mode_Battery)
		{
			//switch to power save mode
			SMCR = (1<<SM1) | (1<<SM0) | (1<<SE);
			sleep_cpu();
			
		}			
    }
	return(0);
}
