attiny2313 serial communication

[eray81]

Hi,
I want to send data with attiny2313 to atmega32 mc. I use code below, but it doesnt work. when attiny2313 sends data to atmega32 , i cant see the right data on LCD connected to atmega32. what may the problem be?

#include <avr/io.h>  

  #include <avr/interrupt.h>  

  #include <util/delay.h>  
#define F_CPU 4000000
  //#define BAUDRATE 9600
//#define BAUD_CALC ((F_CPU/(BAUDRATE*16))-1) 
#define BAUD_CALC 25
 int main (void)  

 {  

   unsigned char data=0;  

                UBRRH = (unsigned char)(BAUD_CALC>>8);//Set baud rate
                UBRRL = (unsigned char)BAUD_CALC;//Set baud rate
                UCSRB = _BV(TXEN) | _BV(RXEN) | _BV(RXCIE);
                UCSRC = (0<<USBS)|(1<<UCSZ0)|(1<<UCSZ1)|(0<<UCSZ2)|(0<<UMSEL);//Set frame format

   for (;;){
	  USARTWriteChar(0x01);
	  _delay_ms(1000);
	    USARTWriteChar(0x02);
	  _delay_ms(1000);
	   USARTWriteChar(0x03);
	  _delay_ms(1000);
   }  

   

 }  
 
 void USARTWriteChar(char data)
{
   //Wait until the transmitter is ready
   while(!(UCSRA & (1<<UDRE)))
   {
      //Do nothing
   }
   //Now write the data to USART buffer
   UDR=data;
}

Try

USARTWriteChar(0x31)

instead of

USARTWriteChar(0x01)

.
