Threading

Parallel programming in Meadow.OS is essentially the same as any other .NET enabled platform. Meadow fully supports System.Threading and System.Threading.Tasks as well as the underlying Task Parallel Library methods.

For example code using these technologies, see the following samples in the Meadow.Core.Samples repo:

BeginInvokeOnMainThread​

The MeadowOS class has a BeginInvokeOnMainThread method that enables code to be put into a queue to be executed on the main thread:

Task.Run(() => {
    MeadowOS.BeginInvokeOnMainThread(() => {
        ...
    });
});

Reduce sensor polling threads​

While C# makes developing code to read sensors asynchronously simple, it can be very easy to create threads for each polling sensor. On low-resource platforms like Meadow, too many threads can restrict your performance as the CPU must cycle between contexts. To help with this, Meadow provides the SensorService, which provides a shared sensor polling thread that can be used to read values from all polling sensors at a regular interval.
