Systick Library
===============
This is a general purpose interrupt driven Systick timing library that should work on any STM32Fxxxx.

It has an accurate blocking delay and event timer.

.. note:: Systick must be initialised before use and takes the "1ms-cal-value" as a parameter: "<1ms-cal-value> init.systick"
