Description: * PWM controlled DC motor speed:
* Be sure to find out the principles of the experiment, the experiment used two timer interrupts
* In the forward output T0 interrupt output low, T1 output high, T0 time
* Is scheduled to die, that is the output square wave length is constant, T1 given time
* T0 interrupt program is determined, T1 time is always less than or equal to T0
* Time, T0 so that the output low fixed time intervals, T1, the output is high.
* Reverse principle, similar
* Fosc = 6M
* Use a timer to control the duty cycle of the PWM wave variable
* Press K1, PWM value increases, the duty cycle increases, the motor rotates faster
* Press K2, PWM value decreases, the duty cycle decreases, the motor rotates slowly.
* When the PWM value to maximum (255), or reduced to a minimum (1), the buzzer alarm.
* Wiring: P10: K1 P11: K2 P30: 74LS02 5,6 feet 74LS02 4 feet to 3 feet
* 74LS02 1 feet to DJ DC: J4 Speaker: J5 P31: SIN
