Note: PWM pulse width either less than 30us. 3. motor is -> reverse switch, you must first stop the motor brakes that use instruction, P -> Vh (high); D -> Vh (high); brake stops the motor, then 100ms delay so, then perform reverse startup command D-> PWM; motor began to reverse, reverse the course of the motor speed can be adjusted by the PWM duty cycle permits jump (low time and high time ratio). Note: PWM pulse width not less than 30us. 4. motor back -> forward switching, you must first stop the motor brake that, P -> Vh (high); D -> Vh (high); brake stops the motor, then the delay is about 10ms, then run forward startup command P -> PWM; motor begins to move forward. 5. Motor emergency stop (braking), perform a combination of instruction: P -> Vh (high); -; no other instructions between the two instructions after the order can not be reversed, and D> Vh (high). Application Example 2: Button realized by a simple DC motor reversing switch and brake function, as shown below: Do gymnastics Description: K1 start button for the motor is transferred, K2 for motor reversal start button, K3 brakes for motor forward button. K1 button is pressed, the motor runs forward at this time, lift buttons K1, the motor coasts to stop running. K2 button is pressed, the motor reverse run, this time, the lift button K2, the motor coasts to stop running. When the motor is in forward or reverse, press K3 direct button, the motor is braking, immediately stop running.

Achieved through an external interrupt 0 keys KEY1, KEY2 collection and response; PWM can be any range. However, due to reinstall the software needs a little time, so a minimum PWM duty cycle 32T / cycle, maximum (cycle -32T) / cycle, T is the clock cycle. PWM frequency is reciprocal of the period. If the period of 2400 to use 24MHZ frequency, the PWM frequency is 10kHZ. ************************************************** ******************** / #include <reg52.h> # defineMAIN_Fosc24000000UL // definition master clock # definePWM_DUTY2400 // definition PWM cycle, the value is the number of clock cycles, use 24MHZ frequency, the value is 2400, PWM frequency is 10kHZ. # definePWM_HIGH_MIN32 // limit minimum duty cycle of the PWM output.
