uart_printf : Microchip AVR printf to UART example

This example initialised a UART, redirects stdout to the UART and demonstrates how to print strings stored in program memory and RAM.

File(s):

• arch/avr/examples/printf/main.c

The following modules are exercised:

• px_uart.h : UART peripheral driver
• px_uart_stdio.h : UART stdio redirect module
• px_pgm_P.h : Support for constant data stored in program memory
