Ataco generator is use as a sensor to detect the speed of a rotating motor. The op of the tacho is between Ov and 54 where the midrange (25) is equivalent to that the motor is standstil When motor accelerates CW toward full speed, the tacho al will vary from 25v to 5v and when the input of tacho varies from 2.5 down to Oy means the motor is accelerating towards CCW The Scenario is to reflect the equivalent speed on two SSDs which one will read the equivalent speed of reading 5 for maximum CW (5v) and the other will also read 5 for maximum CCW (Ov) equivalent speed in the reverse direction Taco generator input is connected to PA4, the CW SSD on PORTB and the CCW SSD on PORTO Write ATmega16 program sketch to follow the above scenario REFS1 REFSO Voltage Reference Selection AREF, Internal Vref turned off AVCC with external capacitor at AREFN Reserved Internal 2.5 Voltage Reference with external capacitor at AREF pin ADPS2 ADPS1 ADP50 Division Factor 0 0 0 2 0 1 2 1 0 4 0 0 0 1 1 0 1 1 0 0 0 1 1 8 + 0 0 16 1 0 1 32 1 1 0 64 1 1 1 128
