    HI everyone,

     

    I am new to PIC and just trying to blink a LED on proteus, but the program is not working.

    can anyone give me some useful suggestion.

     

    my program is ..

     

    void main()
    {
         TRISB=0x00;

         while(1)
           {
                 PORTB=0x00;
                 delay_ms(100);
                 PORTB=0xFFFF;
           }
    }

     

     

     

    and in proteus I have just connected to led to pic.

    void main()
    {
         TRISB=0x00;

         while(1)
           {
                 PORTB=0x00;
                 delay_ms(100);
                 PORTB=0xFF;//its a 8 bit microcntroller

                 delay_ms(100);
           }
    }

     

    still u cant find blinking led increase the value of delay and check.

     

     

    All the best

    hello Syed

     

    I have increased the delay but it is not working. do u think that I have to connect extra circuitry like oscillator, ground,power etc.
