...ECET 340 Week 6 HomeWork 6 Purchase here http://devrycourse.com/ecet-340-week-6-homework-6 Product Description 1. What are the four main functions of the HC12 Timer unit? 2. Two input capture events occur at counts 0x1037 and 0xFF20 of the free-running counter. How many counts (in decimal) have transpired between these two events? 3. What is the maximum time possible before the free-running counter overflows when the e MHz? 4. Two input capture events occur at 0x1037 and 0x002A. If the prescaler bits PR[2:1:0] are set to 101 and the e clock is 24 MHz, how much time as transpired between the two events? 5. Calculate the count that should appear in the timer capture register TC0 if a 125 kHz rectangular wave is inputted on timer pin PT0 while TCTL4 is preset for falling edge detection. Assume a 24 MHz e-clock, TMSK2 was programmed with the value $02, and the count of the 1st edge event has already been subtracted off from TC0. 6. Write down the name of the HC12 timer register that should be polled through software to determine whether or not an active input edge has been captured on one of the port T pins. 7. What is the duty cycle of a signal produced by the PWM when and ? a. 28.0% b. 29.8% c. 50.0% d. 72.0% 8. What values are required for period and duty cycle to generate a 6.0 kHz, 95% duty cycle waveform using the PWM function? Assume e-clock frequency is 24 MHz. 9.

...ECET 365 week 1 homework Pgs 454-455 Austin Salankey 5/3/2016 DeVry University 8.9 A stepper motor has 24 North teeth and 24 South teeth. What angle change occurs on each step? If a full step is output every 1 ms (and assuming it doesn’t slip), at what speed does the motor spin? ANSWER: 360°/(4n) = 360°/[4(24)] = 360°/96 = 3.75° Revolutions per Second (4f/N) = 4(1000s)/(96) = 4000/96 = 41.667rps -or- 41.667rps(60sec) = 2500rpm 8.10 Draw a figure similar to Figure 8.80 showing how half stepping works. D8.13) Design an interface for a +24 V, 500 mA geared DC motor. The time constant of the motor is 10 ms. Include software to adjust the delivered power from 0 to 100%. Answer: I chose the TIP120 because it can sink at least 3 X the current needed for this motor. The base current is: I_b=I_coil/h_fe =0.5A/1000= 0.5mA Disired interface resistor = R_(b )≤((V_OH- V_be ))/I_(b ) = 5KΩ Now to make PWM 10 times faster than the 10 mS we go to 1mS; or a frequency of 1kHz // MC912 C32 C // 1 ms PWM on PT0 void PWM_Init (void) { MODRR |= 0x01; // Port T, pin 0 is connected to PWM system PWME |= 0x01; // Enable PWM Channel 0 PWMPOL |= 0x01; // PT0 High then Low PWMCLK |= 0x01: // Clock SA PWMPRCLK = (PWMPRCLK & 0xF8) | 0x04; // A = E/16 PWMSCLA |= 5; //SA = A/10, 0.25*160 = 40 us PWMPER0 = 25; ...
