This example program echoes data sent in on USART1 on the
ST STM32F429IDISCOVERY eval board. Uses interrupts for that purpose.
The sending is done in a nonblocking way.
Board connections:
------------------
PA9 (USART1_TX) TTL serial output (38400,8,N,1)
PA10 (USART1_RX) TTL serial input (38400,8,N,1)
Notes:
------
You can connect the USART to the stlink by closing the SB11 and SB15 jumpers.
