Thermometer using DS1621 and Nokia 3310 LCD interfaced with ATmega8

I am presenting one application with the Nokia 3310 LCD: Designing a thermometer using DS1621 temperature sensor IC. DS1621 is 8-pin sensor from Maxim, with temp range of -55 to +125 degree C, which can be interfaced with microcontroller over two-wire serial i2c bus. It has operating voltage range from 2.7 to 5.5v. I'm operating it here at 3.3v, same as the one driving the LCD and ATmega8. DS1621 doesn't re ...
