Development API documentation

[Mitko Haralanov]

Hi,

I just recently found SimulAVR as part of Klipper's development. I
wanted to use it to test Klipper. What I want to be able to do is
generate async events from the simulation that Klipper will be
responding to. As part of that I would like to write a simulation
script that can set pin state in a user-defined way.

I am searching for documentation on writing simulation scripts.
Tutorials, API documentation, anything. So far, the only things that
I've been able to find are the examples in the repo but those contain
surprisingly little comments/documentation.

Are there any pointers to documentation?

Thank you
