I am searching for an INDI driver to guide a EQ5-DualAxis-Handbox with ST4 input, directly with the raspberry PI's GPIO + optocoupler.
Or is it possible to write my own java-driver for it. But i can't find any BASE-Guider-Driver for java only for c++, and i am not so skilled in c++-development. :/

Maybe someone has done this before?
