…2026) there were no functioning board libraries available, so this is ATTinyCore configured to work again, with DigiSpark example code (only DigiCDC and DigiUSB tested). A package_index.json still needs to be generated and then I think it can be added to the arduino IDE board manager with ease.
Updated README to reflect 2026 working update and added context about fixes and example code.
Added links to Digistump's Digispark repo and DigiUSB helper programs.

Added credit to felias-fogg for his contributions and package_index.json guidance.

Added instructions for adding the board package URL to Arduino IDE preferences.

This core was completely unusable for coding the DigiSpark (Jan 2026) so I made several changes to fix it and get it working with the Arduino IDE. It is probably not up to your standards @SpenceKonde for this project, and thus I expect it won't be merged: but I hope that it will show up in Google search results when other people have problems trying to use a DigiSpark in 2026!

I added some DigiSpark code examples, I only fixed/tested DigiCDC and DigiUSB. I was able to write code to the boards via Micronucleus, as well as ISP, and burning the Micronucleus bootloader through ISP works now. Make sure to set your frequency to 16.5MHz if attempting to do anything with USB!
