Attiny projects?

It's the little chip that can.

;D

I assume you mean the datasheet for the attiny85 on the OSCCAL values?

Yes. Keep the datasheet close at hand. Tiny Tuner provides you with an OSCCAL value. It's up to you to do something with that value.

I installed the cores through links to the site from other posts, I didn't realize that was your site.

I'm trying to keep it from becoming "my site". Anyone want to contribute / help?

Installing it all was a breeze

Excellent!

I'm hoping programming the 85 will be as simple

I think it is. From a software perspective, the core should make working with the 85 very similar to working with a 168 or 328. The big thing lacking are libraries. Most (all?) Arduino libraries will not work as-is on the tiny processors.

Hopefully I'll get the first done soon and I'll post it up!

Please do.

I love the 85, so much so I've built an emulator for it. (CB, got PCBs the other day and have half written a monitor program.)

Nice! Is it the PCB you published in the Hardware / Development section? Did you make any changes from what you published? Did you farm out the PCBs or etch them yourself?
