PIC blinked - standard

q10 family - pic18f
  • MPLAB X - v6.35
  • Proteus - v8.16

The example below demonstrates how to configure the microcontroller to turn on an LED when a user button is pressed. To achieve this, the user needs to identify the pins of the microcontroller routed to the user LED and to the user button.

VSM

  • RC5
    LED
  • RC7
    Button

code

#include <xc.h>
void main(void)
{
    /* setting pin RC5 as output (LED) */
    TRISCbits.TRISC5 = 0;
    /* setting pin RC7 as input (button) */
    TRISCbits.TRISC7 = 1;
    /* enable digital input buffer for pin RC7 (button) */
    ANSELCbits.ANSELC7 = 0;
    /* enable internal pull-up for pin RC7 (button) */
    WPUCbits.WPUC7 = 1;

    while(1)
    {
        if(PORTCbits.RC7) {
            LATC &= ~_LATC_LATC5_MASK;
        }
        else {
            LATC |= _LATC_LATC5_MASK;
        }
    }
}
