the c code for 3 phase brushless DC motor control by using PIC16F877A

[You Wei Lim]

Hi guest , i have face the problem that i need to use the 3 PORT B pin as the input pin from hall sensored from bldc motor, and 6 PORT C pin as my output pin 5V to control the high side and low side of my motor driver the 3-phase BLDC motor by using a C-code programming~~below is my source code ,can compile but dint work~~ ANY SUGGESTION? URGENT!!!!!!!

   void main()
 {
  TRISA = 0xFF;
  TRISB = 0xFF;           // Set PORTB as Input
  TRISC = 0xFF;
  TRISD = 0x00;           // Set PORTD as Input
  PORTA = 0x00;
  PORTB = 0x00;
  PORTC = 0x00;
  PORTD = 0x00;
  CMCON = 0x07;
  ADCON1 = 0b10000110;
  // or
  // ADCON1 = 0b10000111;
while(1)
   {

    if(PORTB =0x14)     // If RA0 is Toggled
     {
       TRISD = 0x00;       // Set PORTB as Output
       PORTD = 0x06;       // Toggle On;

     }
       else  if (PORTB= 0x10)    //0x04 - 100
                        {
                                TRISD = 0x00  ;
                                PORTD= 0x24 ;
                                //hall_state = 5;
                        }
                        else if (PORTB= 0x18)       //0x06 - 110
                        {
                                  TRISD = 0x00 ;
                                PORTD= 0x21  ;
                                //hall_state = 6;
                        }
                        else if (PORTB= 0x08 )        //0x02 - 010
                        {
                                TRISD = 0x00 ;
                                PORTD= 0x09;
                                //hall_state = 1;
                        }
                        else if (PORTB= 0x0C)      //0x03 - 011
                        {
                                 TRISD = 0x00 ;
                                PORTD= 0x18;
                                //hall_state = 2;
                        }
                        else if (PORTB= 0x04)
                               //0x01 - 001
                        {
                                TRISD = 0x00 ;
                                PORTD = 0x12;
                                //hall_state = 3;
                        }
                        else
                        {
                                PORTD= 0x00;
                        }




    }
 }

PLS HELP!!!!!

6 PORT C pin as my output pin

TRISC = 0xFF;

both doesn't have similarities .To configured the any port pin as output its respective TRISCx = 0.

read the datasheet before doing coding and learning the new micro controller that should be basic step for all new programmer for new controller.
