core13: An Arduino core for the Attiny13 *testers wanted*

It looks (from the fuses) like the default clock speed is 1.2MHz (9.6MHz internal RC clock divided by 8), so 1200000L in place of 128000L will fix that.
I can only speak for my chips and my usbtinyisp, but despite the chip having Attiny13A printed on it avrdude and the usbtinyisp wanted to see attiny13 called.

I've been enjoying myself with this thing so far, thanks again :smiley:

My only project that I actually sell and have to buy chips for requires the attiny85's oddball timer1, but I like the concept of working on efficiency and already have a couple projects in mind that should fit quite nicely and require a MCU for long term deployment.
