Maker and Rasbery pi & Jetson nano GPIO access

I recommend running the pigpiod daemon and connecting to its socket interface from a long-lived asynchronous thread. The client-side python module for that project looks jython-compatible, but you might want to optimize it. Python’s socket module is notoriously laggy in jython.

If it didn't work for you, an account of your attempt would be helpful to others. If you didn't even try, that's on you.
