RF-Bitbanger

I have been working a bit with T Andersson, who has written rf-bitbanger. Rf-bitbanger is a device driver for Raspberry Pi that allows writing of pulse sequences to the GPIO-pins. This makes it possible to connect for example a 9€ 433MHz transmitter directly to the RPi and control remote switches without any additional interface components (see picture above).
I have now made a first version of a rf-bitbanger-HomeItem which can transmit all protocols supported by NetHome via a rf-bitbanger port. This means that for only 9€ you can turn RPi into a complete home control system!

    Yes, I also had problems building the rfbb-driver, and I actually ended up asking Mr Andersson for help... But now I think there are good descriptions on the RPi forum. I was considering if I should supply a ready built rfbb-driver with NetHomeServer, but the problem is that the driver has to be compiled for each version of Raspian, so in the end I decided not to do that.

    Great! Tested with Oracle JDK 8 for Raspberry Pi. Seems to work OK!
    Building the rfbb driver depends on kernel headers or source.
    I wrote a small script to aid this process:
