Cpu.Pin Enumeration

Indentifies the General Purpose Input/Output (GPIO) pins.

Namespace: Microsoft.SPOT.Hardware
Assembly: Microsoft.SPOT.Hardware (in microsoft.spot.hardware.dll)


public enum Cpu.Pin


  Member name Description
GPIO_NONE Indicates that no GPIO pin is specified.
GPIO_Pin0 Specifies GPIO pin 0.
GPIO_Pin1 Specifies GPIO pin 1.
GPIO_Pin2 Specifies GPIO pin 2.
GPIO_Pin3 Specifies GPIO pin 3.
GPIO_Pin4 Specifies GPIO pin 4.
GPIO_Pin5 Specifies GPIO pin 5.
GPIO_Pin6 Specifies GPIO pin 6.
GPIO_Pin7 Specifies GPIO pin 7.
GPIO_Pin8 Specifies GPIO pin 8.
GPIO_Pin9 Specifies GPIO pin 9.
GPIO_Pin10 Specifies GPIO pin 10.
GPIO_Pin11 Specifies GPIO pin 11.
GPIO_Pin12 Specifies GPIO pin 12.
GPIO_Pin13 Specifies GPIO pin 13.
GPIO_Pin14 Specifies GPIO pin 14.
GPIO_Pin15 Specifies GPIO pin 15.


Because pin assignments are implementation-specific, this enumeration defines only constant for the first 16 pins and well as GPIO_NONE. When the SDK is ported to a specific hardware platform, it is expected that those who do the port will use this enumeration as the basis of an enumerated type for that platform that defines the GPIO pin assignments. Doing so will enable the platform-specific enumeration to be cast to the type Cpu.Pin. In this way, all SDK methods maintain type safety while still enabling full portability.

To use the correct pin definitions, you probably need to include a using statement in your code. For example, an application that uses the sample Freescale implementation would require the following statement in its .cs files:

using Microsoft.SPOT.Hardware.FreescaleMXSDemo;
