We are asked to build an embedded system to control an oven. The embedded system receives a digital setting on PORTB between 0 and 7 that determines the desired temperature (as shown below). We will use the LM35 temperature sensor to measure the temperature in the oven. - If the temperature is more than 3 C above the desired temperature, the heating element (connected to RCO) is turned off. Otherwise, the heating element is turned on. The oven temperature should be read every second and the user setting on PORTB should be read every 5 seconds. Vss = 0, VDD = 3V, fosc = 100 KHz Setting Temperature OFF 50 C 70 C 90 C 110 120 C 130C 140 C 1997
