This is a demo that uses the System Tick counter in the STM32F4
as a way of creating accurately timed delays. A simple 'msleep'
is implemented by watching the system clock to wait a certain
number of milleseconds before it returns. Its a bit more accurate
than a for loop, although it really shines when your running multiple
threads.
