Chapter 2: Quick Start Guide

C

• e, then New, then C/C++, and name it Blinky.c.
  PE exactly as shown:

#include <avr/io.h>

#include <avr/delay.h>

int main (void)

{

// set PORTD for output

DDRD = 0xFF;

while(1) {

for(int i = 1; i <= 128; i = i*2)

{

PORTD = i;

_delay_loop_2(30000);

}

for(int i = 128; i > 1; i -= i/2)

;

op_2(30000);

• Open File and again save ‘Blinky.c’ to your Blinky directory

•

•

• lick OK.
  Click Fil


• Save in Blinky directory and CAREFULLY TY

// Blinky.c

{

PORTD = i

_delay_lo

}

}

return 1;

}

• NOTE: YOU MUST ADD THE EXTENSION ‘.c’ TO THE NAME
  Open the file ‘makefile’ in your Blinky directory.
  Change these lines:

MCU = atmega128

# Output format. (can be srec, ihex, binary)

FORMAT = ihex
