See theRaspberry# IO Wiki for full documentation and samples.

Raspberry# IO is a .NET/Mono IO Library for Raspberry Pi. This project is an initiative of theRaspberry# Community.

Current release is an early public release. Some features may not have been extensively tested.Raspberry# IO currently supports GPIO input/output, and samples with SPI (for MCP3008 ADC or MCP4822 DAC), I2C (for MCP23017 I/O Expander), HD44780 LCD display and HC-SR04 distance sensor are provided.

Support for extended I/O (such as SDI, or PWM for motor control) is planned for future releases.

Programs using Raspberry# IO must be run with elevated privileges, for example the Test.Gpio.Chaser program included in solution:

sudo mono Test.Gpio.Chaser.exe -loop

Raspberry.IO.GeneralPurpose provides a convenient way to use Raspberry Pi GPIO pins, while using .NET concepts, syntax and case.You can easily add a reference to it in your Visual Studio projects using theRaspberry.IO.GeneralPurpose Nuget.

It currently support the following features:

• Access to GPIO pins through memory (native interop inspired fromBCM2835 C Library) or file (except for I2C) drivers
• Addressing throughprocessor pin number or connector pin number
• Giving custom name to pins for more readable code
• Various Raspberry Pi revisions, for nowRaspberry B rev1 and rev2, including rev2 P5 connector
• Easy-to-use, declarative configuration of pins. Ability to revert the polarity (1/0) of pins; ability touse an input pin as a switch button
• Firing ofevents when pin status change (input as well as output), using polling
• High-level behaviors for output pins, includingblink,pattern andchaser
• Controlled use of resources using a IDisposable component
• Support sub-millisecond polling of input pins
• Preliminary support for SPI through Raspberry.IO.SerialPeripheralInterface assembly
• Preliminary support for I2C through Raspberry.IO.InterIntegratedCircuit assembly
• Prelimianry support for various components through Raspberry.IO.Components assembly
• Includes SPI samples for MCP3008 ADC and MCP4822 DAC, I2C sample for MCP23017 I/O expander, as well as samples for HD44780 LCD display and HC-SR04 distance detector
