- A taco generator is use as a sensor to detect the speed of a rotating motor. The o/p of the tacho is between Ov and 5v where the midrange (2.5v) is equivalent to that the motor is standstill. When motor accelerates CW toward full speed, the tacho o/p will vary from 2.5v to 5v and when the input of tacho varies from 2.5v down to Ov 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.

- • The repetition period of the PWM pulse for servo control is 20 ms. The pulse width is between 1.0 to 2.0 ms, with 1.5 ms setting the servos to the center. • We need a resolution of no less than 1 us (micro second) for the pulse width change. • The timer used for the PWM generation has a 16-bit prescaler and a 16-bit counter. • The clock to the prescaler is 10 MHz. Determine the following (which may not be unique): 1. The range of PSC that satisfies the requirements for resolution and period of the pulses. 2. The value of PSC that can provide us with a PWM resolution, the multiple of which will be 1 us. 3. The PWM resolution for the above choice of PSC. 4. The value of ARR. for the above choice of PSC? 5.
