How to control DC motors with PIC16F877A and L293D-(Proteus + MikroC)

It is very easy to control DC-Motors using PIC16F877A and L293D(H-Bridge). By using PWM(Pulse Width Modulation) we can reduce the RPM of the motor. Here is a very simple code in mikroC to control 4 DC-motors void main() { trisc2_bit=0; //set portc-pin 2 as output pin for PWM1 trisb=0x00; //set port b os output port portc=0x00; //reset port c PWM1_Init(5000); //initialise PWM1 at 5KHz PWM1_Start(); //start PWM1 PWM1_Set_Duty(127); //set PWM Duty cycle while(1) // start infinit loop { portb=0x01; //signal to motor 1 forward direction delay_ms(200); portb=0x04; //signal to motor 2 forward direction delay_ms(200); portb=0x10; //signal to motor 3 forward direction delay_ms(200); portb=0x40; //signal to motor 4 forward direction delay_ms(200); portb=0x80; //signal to motor 4 reverse direction delay_ms(200); portb=0x20; //signal to motor 3 reverse direction delay_ms(200); portb=0x08; //signal to motor 2 reverse direction delay_ms(200); portb=0x02; //signal to motor 1 reverse direction delay_ms(200); } //end loop } //end main copy and paste the code in mikroC and try it.........
