Step2: Select the Standalone option for the project. Pic16F877A MplabX Setup02.png

Step3: Choose the Controller(PIC16f877A) from the device drop down. Pic16F877A MplabX Setup03.png

Step4: Select the required programmer. In this case it is Pickit2 or Pickit3. Pic16F877A MplabX Setup04.png

Step5: Choose the xC8/Hitech compiler which ever is installed. Pic16F877A MplabX Setup05.png

Step6: Provide the project name and project location. Pic16F877A MplabX Setup06.png

Step7: Now the required project is created. Create a new .c/main.c to write the code. Pic16F877A MplabX Setup07.png

Step8: Save the file with C extension. Pic16F877A MplabX Setup08.png

Step9: Type the code or Copy paste the below code snippet and save it

Program:

/* Program By Udaya Prakash Jayaraman */
    #include <pic16f877a.h>
    void delay(unsigned int k)
    {
        unsigned int i,j;
        for(i=0;i<k;i++)
        {
            for(j=0;j<1000;j++);
        }
    }

    int main()
    {
    /* Configure all the ports as Output */
        TRISA = 0x00;
        TRISB = 0x00;
        TRISC = 0x00;
        TRISD = 0x00;

        while(1)
        {
            PORTA = 0xff; /* Turn ON all the leds connected to Ports */
            PORTB = 0xff;
            PORTC = 0xff;
            PORTD = 0xff;
            delay(100);

            PORTA = 0x00; /* Turn OFF all the leds connected to Ports */
            PORTB = 0x00;
            PORTC = 0x00;
            PORTD = 0x00;
            delay(100);
        }
        return (0);
    }

Step10: Build the project and fix the compiler errors/warnings if any.
