+README
+------
+
+This example is the same as fancy_blink except that it uses the
+systick timer to generate time accurate delays. Shows how to set
+up the systick timer to create an interrupt every millisecond and
+how to write a delay routine (msleep) that can then delay for a
+specific number of milliseconds.
