Linux Kernel Module to Control 434Mhz RC Outlets – Pi Version

Added a setup-script to cross-compile the Linux kenel module for the RC outlets for the Raspbarry Pi. To be able to cross-compile the module, in brief the following needs to be done: Install ARM cross-gcc On Ubuntu: sudo apt-get install gcc-arm-linux-gnueabi make ncurses-dev Get RasPi Kernel E.g. use Kernel from GIT: git clone https://github.com/raspberrypi/linux.git linux-raspberrypi […]

Tri-State Protocol of the Pollin (and other) 434MHz RC Switches

Made a overview of how the over-air protocol looks for the Pollin RC Switches (see previous article for more details). The length of the pulses is a multible of 350us. The wave-forms where captured with an OpenBench logic sniffer.
