I know there is an XMEGA chapter of the Arduino community, but can't seem to find much activity. Does anyone here use XMEGAs, and in particular, has anyone used the TCx0+AWEXx combination in Pattern Generator Mode with Common Waveform Channel Mode? This thing is driving me mad, and driving me to bankruptcy! 
Not me.
I'd ask on AVRFreaks, they have a dedicated xmega board
EDIT: nevermind, looks like you already asked there!
Yep, I posted there first and I've already got more responses here. C'mon you Freaks!
