Attiny2313 flashing LED examnple
This was one of the first Attint chips that I looked at, so I decided to create a simple DIY development board (more on that later) and create some basic examples to play around with
Not a very exciting example, just the usual flashing LED example with a couple of LEDs connected to our attiny, lets look at the schematic.

Code
We wrote this example in Atmel Studio. Fairly basic stuff here, set PORT D as outputs, switch on the LED connected to PD0, then the PD1 LED on, both LEDS on, then switch them off.
#define F_CPU 1000000UL // 1 MHz
#include <avr/io.h>
#include <util/delay.h>
//
int main(void)
{
// LEDs are on portD 0 and 1
DDRD = 0xff;
while(1)
{
PORTD = 0x01;
_delay_ms(500);
PORTD = 0x02;
_delay_ms(500);
PORTD = 0x03;
_delay_ms(500);
PORTD = 0x00;
_delay_ms(500);
}
}
