MinimOSD + Arduino

Hello everyone

I am working in my thesis in a project that i had to work with an MinimOSD, so forgive me for bothering. I need to connect an MinimOSD to an Arduino board to get some sensor value over an FBV camera. So i am trying to find what protocol does MinimOSD work with but i did not found alot of info about this topic could anyone help me. Here is a schematic that i have made for the project.

Best Regards
