A simple C# wrapper for Gordon's WiringPi library.

WiringPi.Net

A simple C# wrapper for Gordon's WiringPi library, also on GitHub. Please note this was only tested with the hardfloat version of Raspbian using CrashOverrides mono build which can be found here: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=34&t=37174&hilit=c%23+experimental

Simply install Gordon's WiringPi library on your Raspberry Pi and create the shared libraries as follows:

cc -shared wiringPi.o -o libwiringPi.so

cc -shared wiringPiI2C.o -o libwiringPiI2C.so

cc -shared wiringPiSPI.o -o libwiringPiSPI.so

Compile the project in Visual Studio 2010 and copy to your RasPi via FileZilla or some other SFTP client. Then run with: sudo mono SPITest.exe With nothing connected to the GPIO header you should see:

SPI init completed, using channel 0 at 32MHz for loopback testing All zeros read back

If you short the MISO and MOSI pins together you should see:

SPI init completed, using channel 0 at 32MHz for loopback testing Loopback is connected!

This is a different project to another .Net io library in that the SPI is hardware based and not software driven, the same with the I2C interface.

All praise should really go to Gordon@drogon for his great library which exposes all the required interfaces making my life and others that much easier. Cheers Gordon!!
