This example using the wrapper (uart.c and uart.h) for the UART-driver from Atmel's application note AVR1307 (usart_driver.c and usart_driver.h) which uses avr_compiler.h.

This example uses the wrapper to receive a byte and to send this byte back in a formatted text string.

Note

With the internal RC-oscillators 2 MHz or 32 MHz, it can be necessary to calibrate this internal clock.
