The LM35 from National Semiconductor is a Centigrade temperature sensor with three external connection pins. The pin assignment and circuit connection for converting temperature are shown in Figure E12.14. Use this device to construct a circuit to display the room temperature in Celsius. The temperature range to be converted is from -27°C to 100°C. Describe the circuit connection for a digital thermometer made up of the HCS12 and the LM35, and write a program to display temperature on the LCD.
