Code:
char printbuff[100];
double d = 0;
int d1 = d;
usart_init(BAUD_PRESCALE);
usart_pstr("TEST DS18B20 \n" );
//init interrupt
sei();
while(1)
{
d = ds18b20_gettemp();
//printf(printbuff,"%d",d1);
sprintf(printbuff, "%.2f", d);
usart_pstr("Temperature:");
usart_pstr(printbuff);
usart_pstr("\r\n");
_delay_ms(500);
}
