Application Example 1:
MCU with a PWM DC motor speed control, reversing switch and brake function, as shown below:

 photo 4_zpsb577e0ab.jpg

Note: If the IO and P, D connection is not strong internal pull-up resistor, you need to add an external pull-up resistor 10K, such as microcontroller 89C51 / 52 series of microcontrollers

Programming notes:
1. system power on initialization, it is recommended with P, D connected I / O are set to high (Vh), namely P -> Vh (high); D -> Vh (high); motor in brake status.
2. motor is transferred to start, we recommend using the command: P -> PWM; motor starts forward, forward the process by adjusting the PWM duty cycle (low time and high time ratio) to change the motor real-time speed. 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:

 photo 5_zpsc475cf5b.jpg

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.

Load test:
1. connect to 2.4 ohm power resistors, power supply 24VDC, PWM control signal frequency 20kHz, 90% duty cycle, the output current of 8.83A, as shown below:

/ ************* Function Description ********************************** ********
This program demonstrates the use of SCM STC15F2K60S2 DC motor drive control board connection module, DC
Reversible motors, brake control;
By doing 16 Timer 0 auto reload, interrupts, IN11 and IN12 output from PWM.
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.
