Question
I have project in microprocessor class that I need to turn on and turn off led of tap light by the button I need an explanation of that please How to do it please and I need the code for that .I will use MBLAB X program to do that project

Explanation / Answer
#define _XTAL_FREQ 8000000
#include <xc.h>
// BEGIN CONFIG
#pragma config FOSC = HS// Oscillator Selection bits (HS oscillator) #pragma config WDTE = ON // Watchdog Timer Enable bit (WDT enabled)
#pragma config PWRTE = OFF // Power-up Timer Enable bit (PWRT disabled)
#pragma config BOREN = ON // Brown-out Reset Enable bit (BOR enabled)
#pragma config LVP = OFF // Low-Voltage (Single-Supply) In-Circuit Serial Programming Enable bit (RB3 is digital I/O, HV on MCLR must be used for programming)
#pragma config CPD = OFF // Data EEPROM Memory Code Protection bit (Data EEPROM code protection off)
#pragma config WRT = OFF // Flash Program Memory Write Enable bits (Write protection off; all program memory may be written to by EECON control)
#pragma config CP = OFF // Flash Program Memory Code Protection bit (Code protection off)
//END CONFIG
int main()
{
TRISB0 = 0; //RB0 as Output PIN
while(1) {
RB0 = 1; // LED ON
__delay_ms(1000); // 1 Second Delay
RB0 = 0; // LED OFF
__delay_ms(1000); // 1 Second Delay
}
return 0;
}
First statement #define _XTAL_FREQ 8000000defines the clock frequency of the microcontroller which is used to calculate delays in __delay_ms()function. Second statement #include <xc.h>includes the header file xc.h which contains the definition of __delay_ms() function and TRIS, PORT registers.
Next is #pragma config directives, which is used to tell the compiler to set Configuration Bits of PIC Microcontroller. You can generate it using the MPLAB IDE.
