Apropos the last two words above, I've had a bit of a google for a windoze-free path to the programmed ATmega328 needed for an UPDI interface, but haven't figured that out yet. Does anyone have a link to a Linux-only guide, just using the gnu toolchain & avrdude? I.e. no arduino dev environment hocus pocus. (I have an old Atmel STK500 for programming the interface ATmega) Those "sketch" things are in C++, IIUC, so just grab the source and whack it through avr-g++? Erik
