ATMEL ICE and Series 1 Tiny via UPDI issues. At this point, I would suspect driver problems. If you have another PC (preferably one that hasn't had AS7 installed before), try a fresh install of AS7 on it, and then see if the...

Can two Event Generators trigger one Event Channel? It depends on which AVR you are considering.
With the newest addition to the family (AVR128DA), I believe it will be possible to combine your comparator event and GPIO input...

ADC Noise Canceller This idea is completely untested. AVR's always execute one instruction after an interrupt before another interrupt is serviced. IF this also applies to exiting sleep (as I believe...

at90usb1287 - very slow response on PC7 On another note: AVR's usually work more reliably when all power pins are connected. You seem to be missing pins 52, 53 and 63.

Chapter 4.6 is also worth a closer look (Power Supply, Power Routing, and Decoupling Capacitors)
I think this problem just begs for you to use DMA transfer. That'll free up even more cycles for the application.

I know I'm a bit late, but I want in on the action too.
