Thanks for answer.
I think it could be possible to use EVOK on web based systems, but problem is with embeded solutions.
It means there is no Raspbian but only for ex. Win 10 IoT with static start application which will communicate directly to unipi throught GPIOs.
Do you have any UniPi I2C API description how to communicate with it?
Because I didn't find it in you docs so I assume that is your internal documentation, and the only way for check how it works is reverse engineering evok.
In other way it could be possible to use Evok, and Mono application loaded on afeter bootup raspbian.
