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: http://www.youtube.com/watch?v=Om0wTqFA-Dw&feature=youtu.be I've always liked the XMEGA Event System, and I think it's widely underutilized. Good luck on your new design! :-) Eric Weddington > -----Original Message----- > From: [email protected] > [mailto:[email protected]] On > Behalf Of Rick Mann > Sent: Thursday, February 14, 2013 8:45 PM > To: [email protected] > Subject: [avr-chat] Do people like the XMEGA? > > Hi.
