SpiController Class

NuGet: GHIElectronics.TinyCLR.Devices.Spi
Assembly: GHIElectronics.TinyCLR.Devices.Spi
Namespace: GHIElectronics.TinyCLR.Devices.Spi

Represents an SPI bus controller. Obtain one via GetDefault or FromName(string), then create a SpiDevice for each chip on the bus via GetDevice(SpiConnectionSettings).

public class SpiController : IDisposable
