 Hey guys ,

does Arduino support the ATxmega* microcontroller family?
Thx in advance for every suggestion.

check www.avr-developers.com, see if your chip is listed.

There is a list under the avr-developers domain itself ,but it doesn;t lists any sort of ATxmega if i have gauged into the list rightly!

Then I would say no ATxmega support is currently available.

@ Sir Robert ,Yes unfortunately there is no ATxmega, that is why im now building a USBasp (just ordered all the components to solder it on place  ) and use the AVR IDE to programme them.

 thx guys!
Well it is kind of "bad" that Arduino DO NOT support the ATxmega familly ...
Anyways let see which one would macht up with my project. The fact is that I
really need a microcontroller with at "least 80 free pins" , flash memory is that
importan (64kb is enough for my code).

Doesn't the ATMega2580 have 84 free IO pins?
Mount it on a schmartboard breakout board like this
Crystal, 22 pf caps, (or a resonator), 10K pullup resistor, four 100nF VCC caps could all be mounted on the card,
go to town on your IO.

If you can code upto 32k then you can just extend your pin;s using a Shift Registers and they are darn cheap for any implication and work just fine like any other pins, its just this that you have to first know for what you are using the pin;s whether as outputs or inputs and as per that get the shift register's they cost like less than 50 cents US at my place
