Raspberry PI GPIO communication via sysfs

SysGPIO is a class which encapsulate the reading / writing and interrupt handling to/from GPIO pins of the raspberry pi.

Documentation

The online docs are here: http://berndporr.github.io/gpio-sysfs/

The docs/pdf directory contains the documentation as PDF.

Example program

The demo program gpio-int-test waits for an interrupt for 3secs on a GPIO pin. If an interrupt has happened it prints out "interrupt" otherwise "timeout".

To run it type:

make
sudo ./gpio-int-test 22

which waits then for an interrupt on GPIO pin 22.

How to use it in your program

Just copy gpio-sysfs.cpp and gpio-sysfs.h into your project and include the header gpio-sysfs.h in your program. Alternatively, you could import this git as a subproject and include the header in the subdir.
