I had a doubt regarding serial communication of Atmega 162
Can any one help please??
I have initialized the USART by setting bits in UCSRB and UCSRC and passed a value in UDR register..but not able to see anything on Serial port of my PC
I am using 8 bit frame with 1 stop bit.
I have written a simple code shown below.
Please help

#include <avr/io.h>
#include <util/delay.h>

#define F_CPU 10000000
#define BAUD 9600
#define UBRR ((F_CPU/16UL/BAUD)-1)

int main(void)

UBRR0H = (UBRR >>8);
UCSR0B = (0<<UCSZ02) | (1<<TXEN0);
UCSR0C = (1<<UCSZ01) | (1<<UCSZ00) | (1<<URSEL0) | (0<<UMSEL0) | (0<<USBS0);
UDR0 = 0X55;
