Best Timer Approach for PLL N and A Counters Are you sure about the 125kHz? If I'm understanding your description properly it sounds like your "output" frequency would be more like 12.5kHz.
a<b<c in if I do the same and then, when I go back to it later, I never have to remember/wonder what the intention was.

So just remove two cells from your 4 pack and jumper across the two empty slots. Voila, two cell pack!

No because it does have an effect. It forces an IN instruction to be emitted by...

SPI and optimization? The most you should have to do is:
SPDR;This will force a read and discard the results as the definition of SPDR contains 'volatile'.

UART/USB Google suggests that a EvB 5.1 with ATmega644p has a 16MHz crystal, so try with F_CPU=16000000UL.
My ears are ringing!
No DMA? Bummer.

I have a question about the LEDs in this device. Do they cycle through various colors by themselves?
