Wish Are there any plans for support of ATTINY85?

I see that the question has been up before, but it's years ago, so I though't I'd bring it up again.

These boards are tiny, which makes them useful in many situations where size matters more than capabilities. They are also dirt cheap, which makes them useful in some situations. All in all, they fit a niche that other cards can't, and thus are very popular.

Ah, it was that simple...

I just tried to scan, and it didn't find anything. Thanks!

Edit: Now I've tried it, and it appears in the list and I can select it. However, it does not appear as a new entry in Serial port, just the ordinary standard COM1. The Uno and Nano appeared as separate ports.

I selected the correct CPU and tried to run an empty project (the standard "New project in B4R) and it resulted in this:

The at85 has no hardware serial, therefore Serial object is not defined in the at85 definition you added to BoardsManager.

There is probably a SoftwareSerial defined, and you'd have to modify your b4r sketch to use SoftwareSerial.

Well, so I thought, but I even tried to disable serial altogether and comment out that line in the project, and still got that result.

Are you using a Digispark module as you linked to in your first post?
If so look here: http://digistump.com/wiki/digispark/tutorials/connecting.
See it has an additional boards manager URL that's different from the one you are currently trying?
Try the URL from digistump and see if that works.

I had one of these Digispark modules a few years back and never managed to get it working with the Arduino IDE, hope you have more luck.

A Chinese version of the digispark, as linked. Actually, the link is what I ordered from.

I'll give it a try when I get home.

Edit: I apologize for stupid questions. Arduino is a new world to me, I've got a lot to learn...

Tried that link now, didn't get that to work either, though I got a different error. Will try more later.
