I have been playing with the Atmel Product finder all afternoon to try to narrow down a candidate for a new design that needs a USB (Device) interface and lots of Flash/RAM & a couple of UARTS
My brain in swimming with options - I 'shortlisted' 12! candidates which all look like they will do the job - but which to choose?!
Besides the obvious differences in Flash/RAM/EPROM & number of pins - I cannot see any other (substantial) difference to assist in my choice.
Would anyone like to share their experiences with using an ATxmega for a USB device application.
At this stage I think it will be HID but would like to play with CDC (comms port) mode also.
I have seen a few posts regarding the ATmega32U4 etc but I was looking for something with a bit (lot) more Flash/RAM
In particular, I'd appreciate some pros/cons for the following -
ATxmegaXXXA3U (eg ATXmage128A3U) vs ATxmegaXXXB3 vs ATxmegaXXXB3U vs ATxmegaXXXC3
However, any feedback as to your experiences with using ATxmegas in an USB application would be very much appreciated.
