RPIO is an advanced GPIO module for the Raspberry Pi.

• PWM via DMA (up to 1µs resolution)
• GPIO input and output (drop-in replacement for RPi.GPIO)
• GPIO interrupts (callbacks when events occur on input gpios)
• TCP socket interrupts (callbacks when tcp socket clients send data)
• Command-line tools rpio and rpio-curses
• Well documented, fast source code with minimal CPU usage
• Open source (LGPLv3+)

Visit pythonhosted.org/RPIO for the documentation.

The easiest way to install/update RPIO on a Raspberry Pi is with either easy_install or pip:

$ sudo apt-get install python-setuptools
$ sudo easy_install -U RPIO

After the installation you can use import RPIO as well as the command-line tools rpio and rpio-curses.

Debian packages are available at metachris.github.com/rpio/download.

You can find lots of examples inside the documentation, as well as in the /examples/ source directory.
