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.

The xpcc library main features are:

• efficient object-oriented C++ API,
• support of AVR and ARM Cortex-M based micro-controllers from Atmel, NXP and ST,
• build system based on SCons and Jinja2 template engine,
• cross platform peripheral interfaces: Gpio, Uart, I²C, Spi, Can,
• write once, run anywhere external IC drivers using these interfaces, and
• lightweight, non-blocking workflow using timers and cooperative multitasking.
