I'm about to start my first project involving touch sensing, I've noticed that the only non-SAM device that has hardware support for touch is the ATmega328PB (according to Atmel's website). As one might expect it's not the perfect candidate for my application but I can not find a comparison between it and the all-software Qtouch support which is offered for virtually any AVR.
I'm mainly interested in response time, debugging capability through Studio, RAM & code space usage and CPU load.
If someone has some experience or knowledge about these - do share. Thanks!
