#pragma config PWRTE = ON // Power-Up Timer Enable
#pragma config BOREN = ON // Brown-Out Reset Enable
#pragma config LVP = OFF // Low-Voltage Programming Disable
#define _XTAL_FREQ 8000000 // Define clock frequency (8 MHz)
void main(void) {
TRISB0 = 0; // Set RB0 as output
while (1) {
RB0 = 1; // Turn LED on
__delay_ms(500); // Wait for 500 ms
RB0 = 0; // Turn LED off
__delay_ms(500); // Wait for 500 ms
}
}
