[SOLVED] Serial Communication Problem in Atmega32

[Briez]

I Want to communicate PC with atmega32 so i wrote a c code for it and made hardware for it, But communication doesn't work...........

Someone Please help me to sort out this Problem,

I am Providing My Circuit and C code..........

#define F_CPU	8000000UL
#include<avr/io.h>
#include<util/delay.h>
#include"LCD.h"

#define BAUD 9600
#define MYUBRR (((F_CPU / (BAUD* 16UL))) - 1)

void uart_init();
void transmit( unsigned char data );
unsigned int usart_getch();

	uint8_t mybyte;
	unsigned char count=0;
int main(void)

{

	DDRB|=0xFF;
	DDRA|=0xF0;

	lcd_init();	
	uart_init();

while(1)
	{
		mybyte=usart_getch();	// get data from serial port
		lcd_cmd(0xC0);			
		lcd_data1(mybyte);		// write data to LCD
		transmit(mybyte);		// send data back to the PC (HyperTerminal)
	}
return 0;
}
void uart_init()
{
/* Set baud rate */
UBRRH = (uint8_t)(MYUBRR>>8);
UBRRL = (uint8_t)MYUBRR;
/* Enable receiver and transmitter */
UCSRB = (1<<RXEN)|(1<<TXEN);
/* Set frame format: 8data, 2stop bit */
UCSRC = (1<<URSEL)|(1<<USBS)|(1<<UCSZ1)|(1<<UCSZ0);
}

void transmit( unsigned char data )
{
/* Wait for empty transmit buffer */
while ( !( UCSRA & (1<<UDRE)) );
/* Put data into buffer, sends the data */
UDR = data;
}

 
unsigned int usart_getch()
{
	while ((UCSRA & (1 << RXC)) == 0);
				// Do nothing until data have been received and is ready to be read from UDR
	return(UDR); // return the byte
}

Where is your interrupt routine?

Thank you a lot for Reply
But,
My Dear Friend,
I can understand your kind reply but i want to make serial communication without use of Interrupt, the code given above by me was taken from expert website but i am facing problem on that.........
Please give me solution without use of interrupt technique......

Please Reply me fast i want to implement it Urgently.......... Thanks....
