Represents an instance of the Microwire/SPI interface for a Microwire/SPI device.
Assembly: Microsoft.SPOT.Hardware (in microsoft.spot.hardware.dll)
public sealed class SPI : IDisposable
The Microwire/SPI interface is a synchronous serial communications protocol in which multiple devices can be connected with one another by means of a single three-wire system. This three-wire system includes the serial data in signal, the serial data out signal, and the serial clock. You must use an additional GPIO pin as a chip select for each device that will communicate on the Microwire/SPI interface.
There are both 8-bit and 16-bit modes of operation using the overloaded read and write methods that have byte (8-bit) arguments or unsigned short (16-bit) arguments. Note that you can configure both 8-bit and 16-bit devices and have them share the SPI interface.
Available in the .NET Micro Framework versions 2.0, 2.5, 3.0, 4.0, 4.1, and 4.2.
