Re: [AVR-Chat] Simple casting winavr

You will need to the I/O library
#include <stdio.h>

You will need to link printf to the USART
fdevopen((void*) Usart_Tx, (void*) Usart_Rx);

You will then need to provide the low level "get a byte to/from the USART 
routines (called Usart_Tx and Usart_Rx above)

YOu will also need to init the USART to the correct baud rate.


You might want to get a copy of the AVR Butterfly demo program that was 
ported to WinAVR and look at UART.h and UART.c for examples of Usart_TX, 
Usart_Rx, and the USART init routine.
