Hi guys (first post),
I recently connected some ATmega16u2 TQFP chips to a DIP adaptor for breadboarding. I want to make the minimal connections to successfully test the ISP connectivity with avrdude.
I have already tried basically connecting to vcc/avcc, miso/mosi/SCLK, /RESET, gnd. i left unconnected uvcc, ugnd, ucap, d+,d- (i don't have a good understanding of whether these lines need to be connected with other external circuitry). Using these connections alone failed.
My programmer is a USBTiny, I am not sure it guarantees support with ATmega16u2... I can't find much on this chip outside the datasheet, which is why i am here.
I am coming from experience using ATmega8 and ATmega8515..
Thanks in advance for your help,
