Re: [avr-chat] Do people like the XMEGA?

[Weddington, Eric]

Hi Rick,

By way of an example, here's an open source project that I ran across real 
recently:

TinyG
"The TinyG project is a many-axis motion control system. It is designed for 
small CNC applications and other applications that require highly controllable 
motion control."
It uses an ATxmega192A3 running at 32 Mhz.
http://www.synthetos.com/wiki/index.php?title=Projects:TinyG 
Code is for AVR GCC and is completely open source (GPL).

Now it may not sound like much. Until you see that a TinyG board has been put 
into an Ultimaker desktop 3D printer to control the motors, with some 
impressive results:

I've always liked the XMEGA Event System, and I think it's widely underutilized.

Good luck on your new design! :-)
