I discovered Xamarin for myself. I already wrote my first cross platform app.
Now I have a special idea. I have a device that I can control via a serial port.
I have already used an Android smartphone and an USB OTG adapter to control the device with an app.
Now I want to write my own app. But I can't find a cross platform library.
Is there a cross platform library?
Or are there several libraries with which this is possible?
(I think the main problem could be iOS)
Thank you very much for your help!
