AVR Freaks

I have drivers for each USART, same code as above but changing the USART name ie

xm_usartc0_s.c, xm_usartd0_s.c, xm_usarte0_s.c

// USARTE0 driver

#include "xm_usarte0_s.h"

// Make  sure that the TX pin is an output in the init sequence
void USARTE0_init(void)
{
	PORTE_DIR |= (1<<PIN3_bp);		//Set TX pin for output

	USARTE0.BAUDCTRLB = (uint8_t) ((F_CPU / (16UL * baud_USARTE0)) - 1) >>8;	// baud register high
	USARTE0.BAUDCTRLA = (uint8_t) (F_CPU / (16UL * baud_USARTE0)) - 1;			// baud register low	
  	USARTE0.CTRLB = (1<<USART_RXEN_bp | 1<<USART_TXEN_bp ); 					// enable receive and transmit 
}

int USARTE0_putchar(char c, FILE *stream)
{   
	while (!(USARTE0.STATUS & (1 << USART_DREIF_bp)));
	USARTE0.DATA = c;
	return 0;
}

int USARTE0_getchar (FILE *stream)
{
	while(! (USARTE0.STATUS & (1 << USART_RXCIF_bp)));  // wait for data
	return USARTE0.DATA;
}

int	USARTE0_unbuffered_getchar(FILE *stream)
{
	uint8_t c = 0;	//Default return value if no char received

	if (USARTE0.STATUS & (1<<USART_RXCIF_bp))
		{
		c = USARTE0.DATA;
		}
	return c;
}
