3.1 Structure of a mikroC Program

Figure 3.1 shows the simplest structure of a mikroC program. This program flashes an LED connected to port RB0 (bit 0 of PORTB) of a PIC microcontroller in one-second intervals. Do not worry if you don’t understand the operation of the program at this stage, as all will come clear as this chapter progresses. Some of the programming elements in Figure 3.1 are described in detail here.

void main() {
 for(;;) // Endless loop
 {
  TRISB = 0; // Configure PORTB as output
  PORTB.0 = 0; // RB0 = 0
  Delay_Ms(1000); // Wait 1 second
  PORTB.0 = 1; // RB0 = 1
  Delay_Ms(1000); // Wait 1 second
 } // End of loop
}
