Simple USART Example
2+
--------------------
3+
4+
This example sets up a USART port and provides a few simple
5+
character handling functions to that a short interactive program
6+
can be demonstrated. It re-uses the clock setup from systick_blink
7+
and that means you could do times delays but that aspect isn't used.
8+
9+
After this example we do character handling with interrupts.
