I am working on my first project with XMEGA (atxmega16a4u) which is a USB PC peripheral that implements a serial port and a HID mouse. I'd like to use the serial to control the gadget which will then emulate mouse clicks (to be sent back via the mouse endpoint).

 

I have experience with the non-USB ATMEGAs.

 

Please give me pointers on how to get started. I synced LUFA, but the samples there seem to not support the XMEGA architecture, only AVR8. Since I am new the USB, too, I am hesitant to proceed without a working sample.

 

Thanks.

This topic has a solution.

Your best bet is probably Atmel Start!??

Thanks. I went there and entered my XMEGA MCU, but USB didn't show up as a peripheral. Then I went back and selected the USB checkbox in the very first page (where you select chips) and it filtered out all MEGA and XMEGA MCUs from the list.

 

Am I missing something or this tool doesn't support USB for the 8bit MCUs?

Thanks, this is useful. I'll study ASF. So far, I've programmed everything from scratch armed with only the manual and the compiler. (It takes long, but I understand everything)

IIRC, ASF3 is in one USB XMEGA bootloader and some have done the "clean room" approach you mentioned (sometimes that's better wrt licensing)
