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

I'll second Eric's vote: AVR XMEGA is good stuff.

I has an instruction set architecture and peripheral mix that isn't completely schizophrenic (I'm looking at you, Microchip).  And the gcc support is excellent, both standalone and via AVR Studio.

I use the AVR Dragon adapter to debugWIRE, but I have played with avrdude and been pretty satisfied too.

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.

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! :-)
