## A word on threads

By default objects in these libraries are **not thread safe**. This means that access to an object must only be from one thread at a time. When using the libraries you must be aware that they will often run other threads internally for monitoring hardware and firing events. If you subscribe to an event, it will be fired from a different thread. It is your responsibility as a user of the library user to control thread access to the object.

## Supported operating systems

`System.Device.Gpio` is supported on any operating system that supports .NET, including most versions of Linux that support ARM/ARM64 and Windows 10 IoT Core.
