I was writing the firmware for PyPPM 2.0 when I was informed (by the compiler, rather rudely) that the ATmega32U2 doesn't support MULSU, or any multiplication for that matter!
I had no choice but to redesign around the ATmega32U4...
I know the silkscreen logo will get covered by the chip, but I don't care; it just looks too cool not to keep. :)
