I am using as7 and I did it like this:
Go to ToyKeeper folder and download all hwdef-.h and tk-.h
Then go to spaghetti-monster folder and download all fsm-.h, all fsm-.c and spaghetti-monster.h
Then go to anduril folder and download all cfg-*.h files
Then create new project for attiny85.
ctrl+c all text from anduril.c and ctrl+v into main.c in your new created project (you must, of course, delete what is there).
In as7: file>open>file> tk-attiny.h and add this:
#define ATTINY 85
In main.c chose your cfg-*.h file which you need. Its on the begginig.
And remember about this:
It’s works. For me.
