Represents a Microwire/Serial Peripheral Interface (SPI) interface for a Microwire/SPI device.

Namespace: Gadgeteer.Interfaces
Assembly: Gadgeteer (in Gadgeteer.dll) Version: (2.41.500.0)


public class SPI


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 the input 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.
