Hardware abstraction library (HAL) implemented in C++ as a wrapper for Standard Peripheral Library (SPL) aka Standard Firmware Library provided by ST. The purpose is to provide simple and self-descriptive interface for peripherals and make it possible to start using it without reading manuals.

The library has static resource allocation and small footprint.

Interface is loosely similar to mbed Microcontroller Library.
