History

Uwe Hermann ca53311bfc Use __asm__("nop") in the loop-based delays.

Since we recently switched from -O0 to -Os, an increase in the loop count
as well as the addition of __asm__("nop") is required (so that the loop
doesn't get optimized/removed).
The real fix is to add a proper timer-based delay function, of course.

Also, fix a bunch of cosmetic issues and typos.

This example program sends some characters on USART3 on the ST STM32-based
Olimex STM32-H103 eval board (see http://olimex.com/dev/stm32-h103.html
for details).

The terminal settings for the receiving device/PC are 38400 8n1.

The sending is done in a blocking way in the code, see the usart_irq example
for a more elaborate USART example.
