My Dad has recently given me his old AVR Butterfly and I thought I'd do a little bit of playing around with it. Does anyone know of a decent tool chain that is easy to setup and configure for AVR's on OS X? I've found a few tutorials for building my own cross compiler and associated tool chain but it is really quite difficult to spare the time at the moment faffing about with compiling cross compilers. Is there an alternative to AVR Studio on the Mac or some such? Any help appreciated. I'm completely new to the world of embedded programming so I'm hoping it will provide a little fun and something a bit different. Edit : Hmm just found something that looks promising. Let's hope it actually works.
