Is the port functional?
I don't think macsimski ever published a core. At least I could never find one.
The core from saposoft (Alessandro Saporetti) works well with a few limitions: I think the analog read is commented-out. There's no Serial. Two PWM pins are supported but three could be. How to use it and a link to the core are here...
I'm about finished getting his core Arduino 0019 compatible (meaning Serial, tone, and analog read are available). When it's ready, I'll post to the Exhibition forum and publish the source code here...
I was just under the impression that it was only available in surface mount.
Nope. For a while this Summer the DIPs were plentiful. For small applications, the '85 and '84 processors are a nice alternative to the '168 / '328 processor.
Well, I presume its not using the official bootloader. Which one is it then? Hmm...here I come Google.
I don't know if anyone finished a bootloader for it. SuperCow was working on one but I don't know if he's published. In my case, I'm using a Pololu USB AVR Programmer. I know at least one person uses a high-voltage programmer with the '85 processor.
