AVR128DB48 Usart

This is my code, and I want to get the "Hello World" in my terminal window (Termite or Putty) :

#define F_CPU (4000000UL) #define USART3_BAUD_RATE(BAUD_RATE) ((float)(F_CPU*64/(16 *(float)BAUD_RATE)) + 0.5) #include #include #include

void USART3_init(void); void USART3_sendChar(char c); void USART3_sendString(char *str); void USART3_init(void) { PORTC.DIR &= ~PIN1_bm; PORTC.DIR |= PIN0_bm; USART3.BAUD = (uint16_t)USART3_BAUD_RATE(9600); USART3.CTRLB |= USART_TXEN_bm; } void USART3_sendChar(char c) { while (!(USART3.STATUS & USART_DREIF_bm)) { ; } USART3.TXDATAL = c; } void USART3_sendString(char *str) { for(size_t i = 0; i

But this is what I get...

How do I connect to the Terminal? How do I wire the AVR?
