Raspberry.IO.GeneralPurpose

The Raspberry.IO.GeneralPurpose assembly provides access to the Raspberry Pi GPIO pins. This project is available under a compiled form under Nuget : see Raspberry.IO.GeneralPurpose Nuget.

Introduction

Raspberry.IO.GeneralPurpose namespace contains classes that provide three different levels of abstraction from the GPIO hardware pins:

• IConnectionDriver interface and implementations provide raw, low-level access to the GPIO hardware.
• GpioConnection classes and related components provide managed access to input/output pins
• PinsBehavior class and inheritors provide a way to group multiple output pins and affect them a common behavior.

Getting Started

Basic access to the Raspberry Pi GPIO is done as follows:

Declare Raspberry.IO.GeneralPurpose namespace

using Raspberry.IO.GeneralPurpose;

Identify pins on your Raspberry Pi board

Following Raspberry Pin Numbering.

Declare the pins

Here, as an output pin for pin P1-11.

var led1 = ConnectorPin.P1Pin11.Output();

Create a connection to the GPIO

Pins are passed as an argument of GpioConnection initializer.

var connection = new GpioConnection(led1);

Use the connection

The following code toggle led status every 250ms.

for(var i = 0; i < 100; i++){
    connection.Toggle(led1);
    System.Threading.Thread.Sleep(250);
}

Close the connection

connection.Close();
