Introduction

Welcome on the Raspberry# IO wiki!

Raspberry# IO is a Mono/.NET library enabling use of Raspberry Pi IO features with the Mono/.NET Programming Framework.

It provides the following assemblies:

• Raspberry.IO.GeneralPurpose, providing access to Raspberry Pi GPIO pins.

Raspberry# IO is released under the GPL-2 Licence. It is a project of the Raspberry# Community, aimed at providing tools and information about Mono/.NET programming under Raspberry Pi.

Requirements

Access to GPIO pins requires elevated privileges that may be obtained using sudo command.

Example

Raspberry.IO.GeneralPurpose

A sample console program is available in the GpioTest project. It must be started as follow:

sudo mono GpioTest.exe [-loop] [-roundTrip] [-width ww] [-speed ss] [-driver memory|file]

Pin settings

GpioTest is targeted to run with a revision 2 board having the following pins (as numbered on connector) wired:

• P1-03 : input (button)
• P1-26 : output (led 1)
• P1-24 : output (led 2)
• P1-22 : output (led 3)
• P1-15 : output (led 4)
• P1-13 : output (led 5)
• P1-11 : output (led 6)

Parameters

• loop: if set, chaser movement is made only once. If not, the chaser movement loops indefinitely.
• roundTrip: if set, chaser movement is a roundtrip between first and last led. If not, it runs from led 1 to led 6
• width: the number of leds involved in the chaser
• speed: the chaser movement speed, in milliseconds between two steps
• driver: the connection driver, either memory or file
