Batch replaced to use new api. User code doesn't need this, but examples should be up to date, and this avoids deprecation warnings.
Simple USART Example -------------------- This example sets up a USART port and provides a few simple character handling functions to that a short interactive program can be demonstrated. It re-uses the clock setup from systick_blink and that means you could do times delays but that aspect isn't used. After this example we do character handling with interrupts.
