Your first program can be as simple as toggling an LED on and off. Here’s a basic example of how you can write a C program to achieve that:

#include 

void main(void) {
    TRISAbits.TRISA0 = 0; // Set RA0 as output
    while (1) {
        LATAbits.LATA0 = 1; // Turn ON LED
        __delay_ms(500);
        LATAbits.LATA0 = 0; // Turn OFF LED
        __delay_ms(500);
    }
}

3. Compiling and Uploading

After writing the code, compilation can be done directly from the IDE, which will generate a HEX file for your program.
