This talk introduces the xpcc framework for efficient object-oriented programming for micro-controllers. Originally developed by the Roboterclub Aachen e.V. for the Eurobot competition, xpcc became a separate project in 2009 and since then focussed on a new approach to cross target microcontroller libraries. It stands out for its extensive use of static C++ classes and templates which is unusual in this field, but lends itself well to the static nature of embedded development. The main goal of xpcc is to provide a simple API which is efficient enough to be deployed on a small ATtiny, yet powerful enough to make use of advanced capabilities found on 32bit ARM Cortex-M.
