Hi,
I recieved my AVR programmer device last week so, i wrote my first LED blinking program in C (AVR). I used ATMEGA328P-PU chip. Earlier i have assembled my own arduino board so i used the same board for AVR by erasing the bootloader. below is my code
Please note that my LED is connected on PIN13.
I will be also writing pushbutton code which i will be posting here soon.
Cheers,
Ujjwal Soni

#include <avr/io.h>

/*

Connect a LED between pin 13 and GND.
*/
void delay()
{
unsigned char counter = 0;
while (counter != 50)
{
/* wait (30000 x 4) cycles = wait 120000 cycles */
_delay_loop_2(30000);
counter++;
}
}
int main(void)
{
/* Initialization, set PB5 (arduino digital pin 13) as output */
DDRB |= (1<<PB5);
while (1)
{
PORTB |= (1<<PB5); //arduino digital pin 5 -> 5V
delay();
PORTB &= ~(1<<PB5); //arduino digital pin 5 -> GND
delay();
}
return 0;
}
Please note that my LED is connected on PIN13.
I will be also writing pushbutton code which i will be posting here soon.
